High quality shift springs with a special hi-efficiency coating to resist heat build up
and keep spring tension consistent from the start of a moto all the way to the finish line.
Springs with just the standard coating will build up heat and the spring tension will change
causing erratic shift patterns.
Different spring tensions are available for matching your clutch to your pipe and other
engine modifications.
The heavier the spring tension the higher your RPMs will be before shifting.
