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.

While this package is more money than a bore-only engine it  is the real deal and the best engine option available for the CR250 hands down.
