High quality compression spring 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 different types of riding. The stronger the spring the higher the engine will rev before launching out of the hole.
