Rear wheel widths
Howdy,
I've posted a snippet of my introduction I was told you folks could probably answer.
On the bike, It now has a KK frame with Buell M2 wheels front and rear and X1 inverted forks. Which leads me to the question that has drawn me out of lurk mode. Is the hub width and centerline of the Buell 5.0 wheel (170/60-17) the same as the 5.5 (180/55-17)? I'm to the point of buying sprockets, and have the narrower of the two, and won't need the 5.5 until I start on the rear fender.
Any money saved buying another wheel right now may be better spent on just getting it drivable again!
Thanks in advance,
-DH

The way I would go about it is, put the wheel you have on the bike, and center it. When you have it centered you can use the parts you have to get an idea where you need to be. Do you need a sprocket, or can you space the wheel pulley? Need more info to help you more.

I have a 170/60-17 wheel &tire mounted. As I recall, the centerline of the hub is offset a quarter inch. Due to frame width, I'll have to run chain drive. I see later model Buells with a 180/55-17 rear tire and want to know if the hub geometry was changed when the rim width was increased the half inch. Fabbing new aluminum spacers for centering isn't so much my concern as the potential difference in the relationship to the drive sprocket.
I hope that was clearer. I have a a rolling bike minus drive and wire. At $75 and plenty of elbow grease, I don't want to change front sprockets too often!

As long as the wheel and tire are centered, it wont matter about the hub offset. Vulcan works is where I get the pulley spacers, best price. Hope I have answered you questions.

That'll work! I think I'll send PBI some money for sprockets. I wanted to set the rear fender up to run a 180 rear. That way I can use the 170 later if need be. I made my own spacers on a CNC lathe at work, so swapping them is just an issue of getting a couple minutes to spare. I'll probaby turn the drive spacer/s as well.
