The key is the center line of the swingarm pivot relative to countershaft sprocket, and the distance between the two. I haven't seen many Aprilia RS250s that have been converted, but remember those Cup bikes are lacking compared to full-on purpose-built GP bikes.

Rising Sun Cycles?

I agree the TZ is the way to go. I wanted to build an all Honda bike but I don't think that's realistic after doing some research. I have ran across several Aprilias but I would rather go with the full out GP chassis. I want to give Trey the best package I can.

I don't know about the Aprilia 250 either but i'll bet you can find them cheap. Ive ridden a few of the 125s at the track and they handle extremely well and are easy to ride. give Ashley Peterson a call too. We were chatting awhile back and he was mentioning a guy with an RS Honda chassis if you go that direction.

The Aprilia 250s are fantastic, but long in the tooth now and parts are $$$.

like i said. get with Dean on the bike's whereabouts. There's a lot to the swap, its pretty complicated and requires quite a bit of custom work, machined parts, etc. If you can find my old bike, that'd be the way to go.

this place specializes in TZ250/thumper swaps, mainly big Rotax's, but they might have some rollers or know the best place to find them if you still want to build your own. JD's bike sure looks nice though!

I remember that bike! Last time I saw it we were loading you in a helicopter. Or maybe I dreamed that?
