    Anyone else on the forum with chain conversion? I need to replace my sprockets and chain and curious what products you have on your bike.

    I have vortex 520 on the rear, with an RK chain, and not sure what kind of front. I haven't taken it off yet to see who makes it.

    Just curious to see what else is available to Buells. I'm not finding much. Options are extremely limited!!

    that gates part is not correct. this info has been floating for 5 years and it keeps coming back.. lol
    get the idler and spacer from EBR. I get my idler sprockets from EBR and the spacer.

    mount in your current arm and make the upper bolt slotted to allow adjustment. then get either 520 or 530 parts. PBI makes the 520 parts and is what I recommend IMO...PBI277X is the main part number then followed by tooth count get a 21 front.

    front

    http://shop.pbisprockets.com/product...2&categoryId=3Direct bolt on no mods needed.

    rear

    https://www.vortexracing.com/shop/sprocket/111/ This fits from 2003 to 2010 Buells disregard the year they are all the same on this part.

    Idler spacer

    then get any 520 chain you like.

    This is a real kit that works and not a Jerry rigged mess...

    Hope this solves all issues. I have been supplying these to people for years as per request for racing and its what we use on our race and street bikes...

    This guy is a Crew Chief on a Championship Buell running multiple classes. Plus I support a few other teams whom have championships now riding Buells. I can assure you that gates plastic part will not hold up...

    lucky him on the gates part. But, I cant recommend the Gates part.Its made from:

    Material: Thermoplastic
    Outside Diameter (mm): 76

    It is a great belt replacement pulley but not a chain sprocket.Intended use is Belt/sprocket not a chain sprocket.

    A little off the subject but why is there an 1125r conversion kit? Is this the only way to use a chain? Can you not just change the idler wheel and rear sprocket?

    Xoptimizedrsx, anrkizm, and turboraven thanks for the quick responses. I didnt even think to look on EBR site for the idler.

    Anrkizm, do yu know if this is a sealed chain? Talked with RK Excel today and they recommended a sealed chain.

    Any thoughts or opinions on these chains? I don't want to buy some POS and it break loose while riding.

    Xoptimized, that link takes me to the vortex site, but not the specific item. Is it the 827?

    And how big of a difference would it make adding or reducing a few teeth?
