Great motor for the money! Was pretty much a direct swap in for my 1984 Honda ATC200X. Now we have electric start and way more power than the stock motor had. It's taken a beating for months now and hasn't missed a beat.

    • I fit it in a crf230f with minor modifications.

Perfectly packaged with bubble wrap for shipping protection. Another review mention a crf230f as a direct drop-in but be prepared to do modifications. Once I successfully installed it & after a few heat & cooling cycles, I changed the shipping oil to 10w40 conventional. I gently ran it through some gears to run it in within the same day I received it from UPS. Seems like a good engine with easy clutch pull & standard 1 down 4 up shift pattern. Sleek engine that looks good in the bike. ... show more

    • Great little engine for a Honda XR250R.
I mounted this engine onto a 2002 Honda XR 250 R. With some slight modification to the motorcycle frame this engine fits well for that application. Once I hooked everything up, the air engine started right up and seems to be very reliable.
