125 National Titles and counting!

All Storm Motor Packages have undergone extensive dyno and race testing. We have spent countless hours at the dyno testing every area possible. Porting configurations, cylinder head shapes, case volume changes, reed modifications, carburetors, compression, fuels, pipes, silencers, we have tried it all.
We specialize in ONLY Cobra 50cc motors. We don’t know a little about lots of motors, we know a lot about this one. The results speak for themselves!
