Nobody in North America has built more Triumph Daytona motors than we have! We have built countless versions of the 675 including 711cc, 750cc, and 765cc versions. The big bore versions are trackday favorites and will smash everything that the track including S1000RR's and 2015 R1's!


The R6 continues to dominate the field in middleweight road racing. We have sponsored and support multiple riders that lead the field in WERA and CCS competition. We build many variants of the R6 ranging from rulebook compliant high compression race gas motors to pump gas 636cc trackday motors.

GSXR's, CBR's, & Ninja's

We love these guys too! We actually had the pleasure of going on a private shop tour of the original Yoshimura race shop in Japan with Fujio Yoshimura, (the son of Pop Yoshimura).

Each engine is personally built by Jamie Hanshaw. Contact Jamie for more information.
