I have a Rotax FR125 for sale. The engine had a new cylinder and piston done at the beginning of last season by J3 Competition and it has maybe four hours of club racing on it since. Previous owner did the metal gear update, but the engine has the old style clutch. The pipe has a couple dings in it but otherwise the engine is in great condition. Comes with basically everything but a motor mount, including a bunch of spares and tools: extra exhaust matting, jets, clutch driver jig, power valve bellows removal tool, fuel pump rebuild kit..
Engine is sealed and includes passport.
Photos of the engine can be seen at http://www.flickr.com/photos/craigdrabik/sets/72157635439965776/
