Notes: Prices listed are to install stroker kit parts in good condition engine. Should your engine need rebuild parts there will be additional charges. We will call for approval before we install any parts that will have additional charges. (example: main bearings, main seals, trans parts)
Notes: The CR280 is a great all over power improvement. It adds tons of bottom and mid but also revs out on top. This package can be used in so many different applications that there is really nothing it can't do. MX, Woods, hill shooter, dunes, and desert, it does it all well. We can even change the porting a touch for Kart applications. We love this kit and you will too.
It is the real deal and the best engine option available for the CR250 hands down.
