Am in the process of building a 1998 M2 and am fitting X1 forks. Wondering if anyone knows why M2 and X1 Buell's ran a 17mm front axle with spacers to fit the standard 20mm wheel bearings instead of just using a 20mm axle shaft?
I measured the right hand axle hole (22mm)so would think a 20mm axle would be easy to make, getting rid of the spacers and help reducing any fork flex. Has anyone tried this?
Have also heard about the Banke Big Axle Conversion. Anyone using it? Have tried contacting them but have had no reply.
Thanks

Different suppliers, different available parts.

"should we have Showa make custom forks for us?"

"should we have timken make custom bearings for us?"

"should we make spacers, to be able to use readily-available forks and bearings?"

Which would YOU have gone with?

Ratbuell has a point. Suspect the speedo drive on earlier Buells was the limiting factor.
Maybe Buell could not source a 20mm inside diameter drive at the time so they added spacers and a 17mm axle to what they could get.
When they changed to the gearbox speedo drive sensor on later bikes, it was probably cheaper to just add a spacer where the drive used to be.

or plain lazy on HD's part ( I like to blame HD for things like this) there must be a spindle (axle) out there that will fit.the end thread is an absolute eye sore as well.

Yes but if they used a larger axle...they'd have had to source different forks, with larger holes or have them custom made with the new axle diameter.

Which was my point.
