315R Aftermarket Sprockets
Posted 04 May 2012 - 11:36 AM
I had similar problems finding a rear sprocket for an old XR but found a 02 YZ that uses the same sprocket. rocket
Any suggestions, crossreference to other bikes, or links would help.

Other than that you might check other trials bikes or maybe a cr125 of that era. When I rebuilt mine, there were a few small engine parts shared with cr125s and 250s... If that doesn't work you could try having one made, I know there is a place around here that does water jet cutting and they say they have a program for gears and sprockets. I've never asked about having a motorcycle sprocket cut though.

I'll pull the both sprocket this weekend and measure them. The front sprocket looks like a XR200, and the rear uses 6 bolts in a 2 x 3 pattern.
