Whats everybody had their Buell XB up too? I have a 2003 Buell XB9R and I was able to hit 135 mph before I ran out of road. I think I could have got a few more mph until I hit the Rev Limiter. Buell (http://www.buellxb.com)

Is the 5th gear the same on 900 and 1200? 150 160 seems a little high.

I haven't had my first oil change yet so I'm still stayin unger 5g's but on my zx11 ninja 194mph clocked by radar. My foot fell off passenger peg and was flapping in the wind like old glory. It took alot just to put it back on the peg.

O5 xb12R,

Unless you've done some final drive/transmission mods, I HIGHLY doubt-- it's impossible that you've gotten to 150-160, WITHOUT blowing up the motor. Also, I don't think the firebolt would be very stable at 150-160, being that it's a semi naked bike, and it's short axle to axle. I know this is a new forum, but I wasn't born last night. Your top speed wouldn't impress me anyway, you passing me in the twisties would. Enjoy.

- I've bounced my 12R of the rev-limiter around 136-138, which is about all the twin can put out. a Sixth gear would be nice for cruising at highway speeds (lower rpm/fuel consumption), but I don't think it would make much of a performance gain since you're still operating with 2 power pulses per rev, as opposed to 4. Also the Buell wasn't designed for blistering speed, it was designed for bottom end, seat of your pants torque, and easy flick-ability. Sorry guys, the production 12's won't be setting any speed records...

azsnow

Other mods that reduce the rpms or alter the rev limiter would have to be done. I don't care if you are pumping out 1000 hp at the rear wheels, the spark is designed to cut out at a certain rpm. Oh, and BTW are you sure you were reading mph, not kph?

It helps when you post numbers and stats that you post everything included. Where are the final drive ratios? Let me guess, next thing you are going to say is that this Firebolt was purchased from the dealer, a race kit was added, then you ventured out to Wendover and ran it...Yeah right! BTW, I have ran at the Salt Flats before, and they don't allow stockers on the course without passing a tech test.

Firebolt, I'm not saying it CAN'T be done.

Engine modifications alone don't increase the top speed. I have an XB12R 2005 just so happens.. and I've been to the rev limiter, on both stock/race ecms. Unless he's changed the rev limiter via re-mapping (which if you did, who did it? - I'd like to know), his rev limiter would be the same as mine. I've mentioned it tops at 136-138 clocked by an r1.

Now, an XB9 however could run that fast since it redlines at about 7300 rpm instead of 6900.

05xb12r-

Theres not much you can say to me, to prove it. and for videos, I care nothing about. Show me a dyno chart with a top speed of 150-160 with an XB12R attached from a reputable shop, then I'll believe you. The final drive ratio, and the maximum "safe" rpm of the motor wouldn't get you above 140
Sorry man, just don't see it happening.

Sorry i didn't take the time to look them up, if you care that much i encourage you to do so. But there's something to be said about a "production class motorcycle".

Yes they can, and they often do. Unfortunately i never topped my bike out before I added my race kit, but i can tell you for damn sure that before I piped my YFZ450 it topped out at 70-72 mph and after it topped out at 80-82. No REV limiter modifications. Same principle.

thats because you never could hit the limiter in top gear with the old pipe ,,,,,motor stoped pulling...changed pipe and pull a little more up top

No kidding,

Basically what they are saying is.. the More horsepower you have, the faster the crankshaft/primary/tranny input shaft/output shaft/Rear sprocket will turn, without the engine turning more Revolutions in same amount of time. If that were the case, I should be able to put 100 hp nitrous kit on the buell, and get one good solid run of say 190mph.. *contemplates*
This thread doesn't merit my response after this statement...

I really thought Buell riders were above all of this. Sounds like the same old pissing contests you find at the rice-rocket forums.
I wonder; if you take an XB12s, replace the ecm with a flux-capacitor, fill the tires with helium, and wore a really spiffy high performance leather leotard, would it make Oprah Winfrey less offensive?

you know mezap its funny you say that, because there is this trend going around now with people filling their tires with Nitrogen saying that it helps with mileage and such. [confused] I dont know about that...

FrAuStY12r
04-13-2007, 10:03 PM
Nitrogen atoms are larger than oxygen atoms.. Since the air you breathe is roughly 70% nitrogen, the other 30% made up of other gasses i.e. oxygen/CO2/Methane/etc. Since nitrogen's pressure/temp correlation is more stable than that of oxygen/other gasses, they're not prone to increasing pressure at high temps, and dropping pressure at low temps (Think filling tire to 36psi "cold" on a day it's 100* outside, then check that tire when its 25* outside, and it will be lower pressure since the oxygen/gasses lose pressure)

Nitrogen- the pressure between hot/cold is hardly measurable, and it doesn't "leak" out of the microscopic pores/tubes in the rubber as oxygen will do.

maybebuell
04-13-2007, 11:12 PM
so i can get better gas milage over time because of proper inflation of tires...will a under inflated tire in 5th gear going 5000 rpm be the same mph with the correct air pressure

We could squeak a couple more mph's on the top end with the proper tire inflation! Just kidding I couldn't help myself. This thread needs to go away.

I'll bet he has flat spots in the middle of both tires because it sounds like he's more into straight lines than twisties. If you are that worried about top end go buy a busa.

Ha, I love a good rumble. I hate forums that try to cut posts, delete, or ban members that get into it a little. As long as you can't shoot some one on a forum than my forum will allow most anything that relates to Buells. I still say that settling issues is best worked out by playing 'spank the monkey' on www.goarcade.us. The high score wins. All bullsh!t aside I've cruised at about 150 mph in my '94 police package camaro for almost 20 minutes before. I was on I65 northbound at 2am. No traffic, and thankfully no cops. I had my Honda CBR 600 F4 up to 110 mph and I thought I was going to sh!t my pants. The Honda had full fairings. I would never go over 80 mph on my Buell XB 12Scg Lightning. The wind might rip me off the bike.

04-14-2007, 11:31 PM
Yeah BuellPartsGuy, I heard something about that as well, but it seems it would wind up being a thorn in the side eventually, once the $$ potential started being exploited. While you can still find free air in a few places, I bet free nitrogen will be impossible to find. I don't mind spending a few bucks here and there, but after a while it gets old, being nickel and dimed to death. Still, its cool to see people being so smart about things. It takes a really bright person to think of things like that!
I wonder if its any more resistant to small punctures? I would freaking love to see someone produce an affordable 10 thousand mile motorcycle tire that would still grip! (hey, if your going to dream, dream BIG! lol)

did 150 once on a honda vf1000r ....can say i remember mush about except looking at the speedo...after 120 mph it all felt the same....watch the vidios on youtube of busa.s doing 170 mph getting up to that speed in no time at all.....just like a strong pull from 70 to 100 now....do the buells pull from 70 to 100 in 5th gear fast I would think that would be one of the strong spots on a buell 12

MrOrange
04-15-2007, 03:18 AM
I had my XB9s at 110 or so today going down I40. I was surprised at how well the bike behaved at that speed. BTW I think it was around 6000 revs, I did not look down at that speed but I remember in the low 5000 range at 90 or so.

do the buells pull from 70 to 100 in 5th gear fast
My XB9 has no problem in 5th gear in that range, I don't think that 4th would have enough revs for 100 especially on a XB12.

maybebuell: What a coincidence. I traded a Honda VFR800 for my XB12! I took that bike up to 130 a time or two, but your right, after 100 or so it all starts to look the same. The thing is, at that speed you are allowed NO mistakes, not even an error in judgement. The bike weighed 580 lbs, so as far as the ride goes that one has probably the best at those speeds, but like Erik Buell says, "How often does the average person go 140 or 150?" That was one of the points he made that sold me on the Buell, and I haven't had ANY regrets. I have so much fun on that bike it blows my mind. If she turns out to be reliable, she can stay forever. (I personally consider the 50,000 mile mark my yardstick, general maintenance excluded) So far its been a great ride. I don't miss going in excess of three digits, didn't do it that much before the buell anyway. 100 mph will get you a ride in a police car, probably a damaged bike when they tow it away, and insurance will become unobtainable. It just ain't worth it, plain and simple. I think if I had to go that fast, I would invest in a track only bike and go to every track day I could afford.

maybebuell
04-15-2007, 03:24 PM
high mph days are over here also...strong pull from 70 to 100 does it for me....love looking at the faces of the metric riders after a strong pull...most dont believe it just happened and the distance you can pull between those speeds can seem like a mile when your behind....i had guys start in 4th gear.. I stay in fifth and still PULL them pretty good....thats whats nice about vtwin power low rpm pulling power

I just bought an 07 XB12R and I also ordered the D&D Exhaust. I want to make sure I don't need an ECM right now when the exhaust gets here and I try and put it on. I want to make sure it's going to run properly, I'm not worried about perfmormance gains what so ever. Just sound and regular stock performance. I will eventually get an ECM in a couple months. Please let me know if the bike will run with the D&D and no new ECM.

WOW!! Bench racing at its finest. Reality is as simple as math and purely dichotomous - right or wrong. Fact: maximum engine rpm (the speed where it hits the rev limiter) divided by primary ratio divided by transmission ratios (secondary ratios), divided by the final ratio (countershaft and rear wheel sprocket) equals rear wheel speed in rpm. Rear wheel circumference of a 180/55/17 tire when new is 77.896 inches, meaning that it travels 77.896" per rotation. Using the required data (primary, secondary, final, and overall ratios) published by Buell (factory service manual), for an '04 XB12S (which is the same for '05 XB12S & XB12R) the following is the maximum speed for all gears for this application.

1st 55.463 mph
2nd 80.647 mph
3rd 104.333 mph
4th 126.438 mph
5th 149.196 mph

The assumptions are that it hits the rev limiter in all gears at 6800 rpm, uses stock gearing, and the rear tire is brand new with no wear. If the tire's tread has worn 3/16" off, it will top out at 148.478 mph. Tire swell is virtually neglible and isn't considered.

Engine mods do nothing to increase top speed IF you are currently hitting the rev limiter in high gear. It will only get you there faster. If you went faster than this, you either - increased the rev limiter speed set point, changed the final drive to a higher ratio (numerically lower), or put a taller tire on the drive axle.

maybebuell
04-23-2007, 03:11 AM
on the highway in 5th you wont pull redline... so that mph will be down...the higher rev will allow faster or quicker 1/4 mile time ..thats probably only in first three gears

First off I live in new york state I travel to and from cohoes to brooklyn new york. The ny thru way I87 I took my bike up to at least 145mph. I had a go down last july ,a cager turned in front of me causing me to believe I was in peril.( I made the mistake of killing all my time braking points and distance) after the bike was (fixed!) meaning k&n air cleaner,race ecm which is not installed by the way.the bike needless to say goes 150mph exactly at the same time the rev limiter kicks in, for real. Just my two cents. oh going 145mph feels alot like free falling out of a plane it also means that the similarity doesnt end there you cant control any other variable except the speed quotient. meaning back off the throttle before some thing runs in front of your bike LIKE A DEER!

138.4 TOP-SPEED. From the dyno at the harley shop I work at. It looks like 140 on the speedo but your full of crap if you think your bike goes 160-170. If you want top speed get a Busa. Otherwise enjoy your bike for what it is, a great handling STREET bike.

Another time I was sprinting past (dead spots) in traffic on the thru-way I passed a car and went on to the next rest stop. This guy walks up and says hey guy how fast were you going back there, I go" look officer"... getting ready to tell him that I got a bad case of the runs,the guy says he's not a cop I say "like 100-120" he goes more like 140-150 cause you passed me like I was standing still. I ask how fast were you going he said 100-110 we both kind smiled at each other like the uneasy smile when you almost get caught screwin your neighbors hot wife, dive out the back window only to land next to the twenty-something year old kid who's banging out the twenty-something year old daughter.

FOR ANYONE WHO THINKS THEIR BIKE GOES 140+!! You are so full of it. Your last bike (probably a ex250) did stand-up wheelies at 110 mph because you have it on tape. I wish my bike was faster but if you want top speed don't ride a air-cooled pushrod motor. The only bragging rights a Buell has it it is a fun street bike that always puts a smile on your face when you ride it. I don't know if you will have time to read this because you are probably busy pulling away from Rossi in the straights but you need to pull your head out!!!

first off there is fudge factor- every speedo even digital has it. at 100mph most are off by 5+ mph.
i had a zx10r and it read 105mph in first gear- radar clocked 101 mph. wide open speed runs showed me 188 mph and i hit the governor, radar checked it was only 174mph. so dont believe what your reading off your speedo.

i must be getting old, that high speed flying low stuff just doenst hold my interest anymore. I am happy putting along at around highway speeds (+ 5-10) I just cant see the need(desire) to do 130+ on a bike with a 52 inch wheelbase. Maybe on a custom bike with a L-O-N-G wheelbase it would be ok, but the Buells are twisty bikes not designed for balls to the walls straight shots, but then a 'busa wont corner like a buell or stop like one either.

years ago i used to work on airplanes, and i find the sticker comment funny. some of the plane designers came up with small stick on vortex generators, which acually disrupted the airflow and gave you an extra few knots of air speed. I say stickers, but i think they were actually stuck inplace then either rivited or bonded on the wing some other way, either way they made the plane look faster and they actually improved the aircraft top speed and made it look kinda cool too.

the vortex generators were 'stuck on' because that was the only way the stc would pass. riveting would compromise structural integrity. - been around a bit also;)

Top on my '03XB9S was 135- cold, clear, night, 3 mile dead run.
Fully loaded into a 30mph wind just outsida Ft.Davis, Tx, I held 120 for over 30 miles.
I was SOOO proud of her that day.

I know my buds on their mildly modified XB12s have topped 142.
150 doesn't seem too impractical under the right circumstances.

u r more then welcome to come run with the big dogs partener.

Sweet..maybe if we ride side by side we can get our bikes up to 320mph....I mean if theres 2 of us going 160 well 160 x 2 = 320mph [cool]

Recorded by a Florida trooper a little over 1 week ago during Daytona Bike Week 2009, on a completely stock Xb9r I did 115mph. The bike was perfectly straight, no wobble no nothing, i was completely tucked looking through my Wiley X's no helmet, no jacket. The bike had plenty more to go. An hour later when the cop caught up to me and the rest of the boys at Pinups, he asked me where do I get one of those? Gave me a fine and walked away. A 6th gear would be pointless, more weight and i would probably never use it.

im 5 ft 11.

it got to 130 fairly fast. 130 to 138 took about ten seconds. Im thinking 138 was more realistic, cause I was looking at the road and just glancing at the speedo.

Ive done about 190 on a built r1. Top speed is not what im into. I like dragging knee going 100, which the buell Is pretty good at.

zoedogg1
03-24-2009, 06:02 AM
I cant believe this thread still exsists. lol.

Just for record: I GPS my top speed at 138 mph. It was a very long straight of way, and it seemed to take at least 3 minutes to get there once getting on it. Im sure it was much less, which is why I say "seemed". 140? Maybe..what 2 mph anyhow? But 150 to even 160? Not without new gearing, etc. For those of us who know better, we actually get a kick out of those higher numbers and how stupid they sound. What gets me after all this time, is that there has never been even one video link of proof.
Anyhow, I hope this link just disappears into a dark void of nothingness...unless someone is willing to post video proof of Buell speeds equal to or greater than 140 mph. Excluding 1125's of course.[smirk]

Unless we are talking about hundreds of pounds difference, minor weight changes would be nearly impossible to notice for any non-pro racer, which is what catagory most likely 100% of the people on this site fall into. Actually, a 200 lb rider would probably feel more comfortable pushing a bike to its limit than a 130 lb rider (nothing personal, just the fact of being able to manhandle a bike at those speeds). Just my input, and I have personally done ~130 on my '03 xb9s with OEM race kit and there was room to grow. I am 180 lbs and 6'3. So most likely my bike would top out at ~140 to 150.

Anyone claiming higher than the manufacturer stated top speed of something like 150 mph does not undestand engine mechanics and gear ratios. One could have 600 hp but extremely small gears and top out at 40 mph. Its called physics/mathmatics.

1001yos
03-29-2009, 05:30 AM
Physically speaking

Ek = ((1/2)m)v^2

Ek = kinetic energy (joules)
m = mass in kilograms (rider + bike)
v = velocity in meters per second

adding or taking away weight won't contribute to any substantial acceleration or top speed since the Ek is proportional to half of the weight. What makes the major difference is the velocity since it is an arithmatic progression (exponential progression) The key is to reduce the speed of the wind (tucking in creates shorter path of wind) or increase the top speed of the pistons (blow your motor)

Top speed is like Limbo. A nice place to visit, but a place you never want to stay at.

I havent read through all of these posts. Did anyone mention "true speed" versus "indicated speed"

Theres no doubt in my mind that if a Buell can reach a true speed of 135 mph that the speedometer may ACTUALLY read 150+mph.

There is sooo much error in motorcycle speedometers at higher speeds its ridiculous. Especially with variables like tire wear.... 10% error in speedometers on bikes is actually low

driftingswiftly

1001yos, you were close with your lecture on the physics of a buell, but not quite right. This system has nothing to do with energy. Yes, it has kinetic energy, but kinematics and dynamics are what determine the potential for top speed. In short, drag is the dominant force to be overcome.

Drag = - .5*roe*Cd*A*v^2 where roe is the density of air, Cd is the scalar coefficient of drag, A is the reference crossectional area, and v is the true velocity of your XB.

Weight has NOTHING to do with top speed, only acceleration. Given a long enough straight away, and identical conditions, every person on this forum will eventually reach the same speed. Tucking (reducing the crossectional area) is the only thing that you can to do actively alter a given bike's top speed.

Of course there are a myriad of minor affects that weight will come into play for, but these are a difference of 1 or 2 mph, not the decades you are all talking about.

In short, this should be modeled with force balances, not energy balances, and accordingly, weight plays no role in the dominant contributions.

Hey drifting swiftly, what about friction between tire and road or are you assuming it's in the same for all bikes in this case. Also wouldn't you have to concider wind resistence, or is that part of the coefficient of drag?

driftingswiftly
03-30-2009, 08:03 PM
Wind resistance is part of the true velocity. It is not taken with respect to the ground, but the surrounding air. And friction b/w the road and tire does not affect it b/c they are not moving with respect to each other (that is the point of contact of the tire with the road).

onelogue
03-30-2009, 08:23 PM
Velocity = distance/time. In your equation, velocity is just standard (ignoring wind resistance) wind resistence has to come into place somewhere.

Ya'll keep in mind that there is a substantial HP/TQ difference FROM THE FACTORY. In cars it has been found to have been as much as 5-15 hp differences. So in a bike it could be similar. Thus accounting for some of the discrepencies found here. Also keep in mind that not all Speedometers are as accurate as they should be. Once again, this occurs most often FROM THE FACTORY..

Stevenc150
04-09-2009, 01:58 AM
They've beat this subject to death, it's not about HP/Tq, like Dan said WAY back
No matter what you do to the motor you won't get it to go any faster than 140 unless you change the final drive ratio lower so it can gain top speed.

driftingswiftly
04-09-2009, 02:14 AM
Fidosols right. There are factory differences in all vehicles.
Stevenc150 simple physics shows that there are MANY ways to make something cut through the atmosphere better. Gearing will make you go faster, but that is by no means the only way.

by the way I weight 175lb. end of discussion.

go out and ride and enjoy this beast. its not a BUSA its a BUELL.

Fido said it already. Speedos can be off from the factory. Some as much as 10%, at 140mph, thats 14 mph in either direction! You could actually be going only 126mph!

I DON"T CARE WHAT YOUR SPEEDO SAYS! Pic's of the radar gun or it didn't happen!

There is also spedo error. My Kawasaki ZRX1200R spedo read 170 but my GPS was reading 150.1 MPH. That was PLENTY fast for me. I doubt once I do get my XB12R I will ever take it to top end but I will try my best to wear down the peg feelers though:) Oh also my Triumph Thruxton 900 jetted and piped hit 125 but I was tucked in tight for that run. Also noted you run out of gas real fast at that speed! (Dont ask me how I know please)

Damn I was so close. My buddy rode my bike while I was in Iraq ( I let him only because he has the money to replace it and a bike for me to hold onto until he does) and he proceeded to tell me how much fun it was ( he rides an HD ultra classic) despite it being a dinky goofy looking bike. He also informed me of hitting around 167 on a very steep downhill stretch. He's my best friend and I couldn't bring myself to call him out on his bull****. I've been trying to convince him to buy a Buell. He says he would never but he sure has no complaints when he hops off after a ride.

138MPH on the GPS. 143MPH indicated. That means 138MPH. Stock REV limit on XB12, pretty sure the XB9 tops out the same.

Tachometer on an xb is analog,although not perfect,its more accurate the the speedo.An xb12 w/ stock gearing and 180/55 17 tire,does the following speeds at the given rpms in 5th gear:3000=61.3,6000=122.6,6400=130.8,6500=132.8,66 00=134.9,6700=136.9,6800=139.0,6900=141.0,7000=143 .0,7100=145.1 if you really want to know actual.this is as close as youll get without a calibrated digital speedo.

How do you figure a MORE naked bike has LESS wind resistance? Also both bikes have the same engine and complete drive train. Make sense of that.

So a big wide pick-up truck would have less wind resistance then a small car with no body panels?

01-15-2010, 01:43 AM
I thought you brought up air drag. Have you ever seen a wind tunnel? Know anything about streamlining?

Air drag is exponential. A ball twice the size of a box will have less air drag.

Oh, by the way Air drag doesn't have any thing to do with the Buells top speed. Last time I checked it still beats the rev limiter in 5th will I'm sitting up in the 140mph wind blast.

Trojan make good products, but you have to remember that their principal market is the UK, where the Buells that got shipped there and to Europe got European gearing, different than US gearing. One of the top mods over there is to switch to US gearing.

1SexyBuell
01-15-2010, 02:49 PM
if the lightnings had better wind resistance then why didnt they use those to race with? because you dont tuck down as much as you would on a firebolt you'd have more wind resistance caused by your body... the front end of the firebolt was aerodynamically made for cutting through the wind

so lost in all the tales of speed I didn't find out what the top speed of a xb12r actually is. I'm gonna guess 135. I'm also thinking this: if you guys are on public roads probing the upper speed limits of the bike you're crazy (call me a boring nutless wonder if you like). I routinely ride in that 85-90mph-zone to allow unchallenged travel in the carpool lane...but riding way up in triple digits is just nuts to me.--should anything go awry bye bye life as you once knew it...or should a cop catch you during your speedracer adventure good bye bike hello jail cell. Someone made the comment about the twisties which I totally agree with. Anyone can blast down the interstate at twice the legal limit, its the dude (or dudette) who can zip through the twisties fast that impresses me.

I had my new 2010 xb9 up to 151.37 mph. It only has 100 miles on the odometer and I was using a my super secret fuel mixture. I wont give the ratios i use but involves nail polish remover, bacardi 151, liquid nitrogen and betty white. Notice the relationship between top speed and bacardi 151

driftingswiftly
05-18-2010, 10:37 PM
I'd be impressed if it was bacardi 151.37. Great way to break in your motor. You should try adding paint thinner and root beer to the mix and see where that gets you. Once I put a laptop in my fuel tank. It didn't do anything.

I'd guess that the .37 mph over 151 flat was due to either a tail wind or me urging it on via telepathic connection.

I just did a top speed on my '07 Firebolt 12R yesterday. I borrowed the GPS off of my '08 Yamaha R1 and I got 139mph indicated but GPS said 124. Funny though, on my R1 the digital speedo stops at 187mph but GPS said 192mph (the Yamaha is far from stock and that was without the nitrous on)....but the Buell is a lot more fun on the streets.

06-23-2010, 05:49 PM
OK well, wow I have laughed ALOT reading all these pages and so far I get that the 12R has gearing for about 140ish.

drag has nothing to do with top speed.
At very low speeds, the effects of aerodynamic drag are minimal. At the same time, the engine can exert a very large force at low speeds, meaning that the acceleration force will be high. At higher speeds, the drag builds up, and the engine's force decreases. Eventually, the drag force and engine force will become equal, leaving no force left for acceleration. It is at this speed that the vehicle is said to have reached its drag-limited top speed.

But I could be wrong, wouldn't be the first time.

I have an '06 Lightning XB12Scg stock, hit 126mph on a long downhill streight. I was WOT in fifth gear but might have shifted to 5th a little early. I noticed that i was crouched down as low as possible at that point, so i decided to pick up my head a bit and immediatly lost approx 5 mph due to the wind resistance. I do believe the top speed is limited to wind drag and wonder if getting a wind screen mod like the 1125 "nose cone" would help this.

My answer to rice riders when they ask me how fast it is... Fast enough to kill you in first gear.

I don't think Aerodynamics has a play in the top speed of the Buells. The rev limiter comes in at about 7000 IIRC, limiting top speed to 146 indicated on my 04 XB12R. If drag where the limiting factor, then the bike would reach it's drag-limited speed before it reached the rev limter. A change in gearing and a change in max RPMs for the Buells might make this happen, but not now.

Alfatango1
02-27-2011, 06:49 PM
I don't think Aerodynamics has a play in the top speed of the Buells.
Got a point here, gearing and rpm limit Buell's to about 135. I've hit an indicated 142 tucked down and 135 recently semi tucked. The later was most likely off by about 10 mph or so. Aero drag may not occur before our Buell's hit their gear limited top speed.

'07 XB12Stt here, 124mph at redline in 5th for about 70 miles from Schenectady, NY to Oneonta, NY in perfect 80 degree weather with zero wind and 70% humidity. If you sit up, you bounce back down to 115 without a thought and almost instantly.

I would love a 6th in this bike, only drawback.
