The 2009 XB12 X platform better in all regards than the 2005-2007 X platform.
I bought a pair of Ulysses a while back. A runner '06 (40k miles) and an '07 with a bad crank. Both are clean. I've been riding the '06 until the fuel pump went out. Parts are here but I haven't had time to replace them. I love the bike.
I bought a running but aesthetically beat (theft recovery) '06 XB12SS to supply a low mileage (15k) good motor for the '07 Uly. I'll be able to use the '06 throttle body etc and should be able to bypass the '07 issues in one fell swoop (crank, unavailable TB, TB butterfly pin breaking, etc), which will mechanically turn the '07 into an '06 Uly.
I picked up a clean '09 Uly yesterday (25k miles). Needs some TLC but I have high expectations for it. I also picked up a wrecked '09 XB12R a few weeks ago. So now I have spare engine / driveline parts for an '08-'09 bike as well.
I'm going to do some mix and matching and put together a "keeper" bike. I'll probably end up selling the 2 other Ulys once I've gone through them and made sure they're in good mechanical condition. I'll be selling one for sure, anyway. Then I'll part out the donor bikes (06 12SS and 09 12R) and the '07 engine.
Having these options in hand...I'm curious. What are thoughts on the two platforms (06 vs 09) as it relates to long term parts availability, keeping on the road, etc? If you had the ability to choose either (assuming comparable mechanical condition), which would you choose? I have an ex-Buell tech friend who likes the '06. He states there's more parts cross-over available (back to the '03 if needed) than the later, 3 year only 08/09/10 generation. For that reason he likes the pre '08 models. I understand that the more the lineage matured, the further they got from their Sportster based roots, with the 8/9/10s being the furthest from them all. However he also left Harley world right before the 8/9/10 generation, so he doesn't have hands-on wrenching time with them. That may be part of his bias.
Maybe it's a largely academic question, but now that I have the options in front of me I'm curious for input from those who know them better than I do. I've got until the spring to tinker with them and figure it out.

Build the best bike.
There are no parts supply issues. Don't put Sportster parts on any of them please. Every time a Buell part gets scarce some people panic that the sky is falling and buy all the ones they can find, most people do nothing until they actually need it and so far the aftermarket and worldwide enthusiasts have filled the small gaps very effectively.
Nothing wrong with the pre-'07 bikes and they'll run perfectly fine with the slightest attention and care.
The biggest change for the '08-up bikes was a better Fuel Injection system (better resolution and IAC, CPS), and also oiling/crank upgrades that resolved a very small amount of issues with the early ones.
Inspect and take the oil pump and drive gear from the 07 to the 06 (if they are in good shape).
I used to think that too, the City-X kept the small brake too so IDK?
Either way EZ R&R swap on to the bike you want to keep. Don't forget to also swap the brake master.
Thanks for that info. I’ll do so. Any other parts from the 07 engine that should stay on the 07? I planned to do a full “drop and swap” with the engine, intake, etc. I plan on ordering another set of intake gaskets and doing the “engine rotation” maintenance items during the swap as well. Rocker box gaskets, intake gaskets, vent valves and O rings, plugs, etc.
