Stage 5 is the superlative of Stage 4 ! Of course all parts of Stage 4 but now with the S&S roller rocker kit (S&S Top End Guardian Kit)  and a special Star Racing custom camshaft.  

​

The costs of Stage 5 are 9250 euros.

(including assembly and adjustment and dyno proof)

​

This kit can also be combined with a Thundermax instead of Diag4Bike for 800 extra. (Recommended)

​

The kit can also be expanded with machining the head with larger valves and seats.

​

Larger Throttle body, a Screaming Eagle head, call for the possibilities........
