Wow that pretty damn impressive for a 250 4 stroke. I wonder what kind of HP the 1998 CR 250 2 stroke I just picked up makes on a dyno. The book says 56 peak which is funny cause my buddies 2011 crf450 only made 52 on a dyno. Kinda makes you wonder why they would go backwards in the hp department. Though I'm sure he makes way more torque than I do.

Wow thats good power and the newer (2010 and up) are suposed to be alot more reliable.
FWIW my sons 08 made right at 40HP but it took a ported head by Chapman,fmf exhaust,high comp piston,Crower cam and race gas.
Seeing this makes me want to get my son back on 250s.:D
