RK Sprockets and Chains are the best in the world.We have dyno tested every sprocket brand and chain on the market and the RK is the best chains in the World, and the best sprocket. Some brands of sprockets last 1-5 hours on the dyno. The RK sprockets last at least 20 hours. Don’t take our word for it. Just ask all the numerous World Champions who use them as well.

O-Ring chains should be used in Junior and Senior classes only. Some individuals will say that RK O-Ring chains cause too much resistance. But this is untrue and we have dyno tests to prove it. In fact at high RPM’s the O-ring chain actually loses less power because we believe it is flexing less then a gold chain.
