What part of it? xr motor in a cr frame, or cr suspension on a xr frame and motor?

Ask the TMGP guys. Billy Weise did a nice XR100 motor in a cr85 chassis with RS125 roadrace wheels. It was stupid good.

Denny rides one in TMGP endurance, oops I think his is a cr85 frame.
Steve had a cr85 frame with an xr motor and rs125 wheels, but I think he sold it.
I bought a cr85 intending to put a xr motor in it but have never started on the project... the closest i came was putting a kx85 front end on my crf100.
There is a frame conversion kit available on line for the conversion or you can send them your frame and they will convert it for you.

Putting the xr motor in a cr frame, I know tk racing makes some conversion parts, but I would rather put the xr motor in the cr frame

Is this for dirt or a motard? I've had both and if you're going to flat track or ride it on asphalt the XR frame with a brace, better fork and shock will be just as good with a lot less work. The CR frame is beefier if you need all the suspension travel, but it's also heavier.

Here's a link to my old bike with pics. BBR did the frame mods...this bike was supposed to be their test mule for the aluminum frame they made. It was really clean and well done. The rear motor mount is the key to getting it right. I never got the chance to tear down the bike and measure that part, but Robin Reeves bought it from me and still has it I think.

I never quite understood the point of slapping a xr100 motor in a CR80 frame other than maybe a cool factor. You're just replacing a fast engine with a slower engine and taking alot of work to do so. Just my opinion.
