30+ Years of Track Experience with World Records to back it up
Grand River Racing has been leading research and development of competition two stroke engines since 1996. We have built engines, exhaust pipes, and chassis for machines that hold many World Records, track records, and class records. Not only have we led the Banshee racing game for over 25 years, we will continue to do so with new technology including CAD, data aqusition, and lightweight materials. Grand River Racing builds any competition two stroke engine including outboard boats, snowmobile drag and oval, karts, motocross, hill climb, ice oval, Hot Saw, Pikes Peak, and even Bonneville land speed records. We build complete engines, exhaust pipes, cut heads, cylinder porting, auto transmissions, chassis fabrication, crankshaft stroking and rebuilding.
