The Honda CBR600RR was the first 600cc engine to utilize a dual injection system in its stock formation. Dual injection offers substantially increased mid-range power over single injection or carburetors. This engine also touts an impressive rev limit of 15,300 RPM. Our Guhl Motors alcohol fuel injection conversion kit features a low profile design and properly sized injectors while still being the lightest CBR600RR conversion available on the market. This is also a member of our brand new LIGHTWEIGHT series of fuel injection systems.
