CBR600 RR4 Dyno Graph

A selection of our cbr engines starting with a stock motor at 105 bhp all the way to 135bhp.

This 125 bhp spec of engine is extremely fast whilst maintaining a great deal of reliability. A hard club racing season is not a problem, requiring no expensive maintenance. The spec of these engines varies quite a bit so call to discuss.

Note (Nov 2006) :- We have now developed a tuning package for this engine using standard cams to maintain reliability and reduce service intervals. This package is making 127bhp with stock headers and modified stock bellmouths and 131bhp with full system and cbc bellmouths. Call or email for further details.
