The NEW TRIPLE roller option with a 1.25 diameter roller creates a very consistent smooth up shift and backshift with improved roller wear. This latest design creates a huge improvement in engine braking compared to our dual roller tuner. All billet construction capable of using compression springs with different spring rate options. We have many helix angles see menu below. We can also provide custom helix angles if you desire for an additional fee.
2015-2016 XP1000 comes with required clutch housing spacer kit part# 2001006.
We also offer the option of a encapsulated helix design that keeps the driven from unloading, opening and going into high gear during breaking and jumping which some racers require.
Can be used along with the stock primary or the STM primary. Best results are acquired when running both the STM primary and STM tuner together.

Number of shims – The amount of shims we install will determine your belt deflection or how tight the belt will be between your primary and driven clutch, keep in mind we are setting the deflection for a stock belt, for an XP1000 choose 3 shims. Keep in mind the more shims you add the looser the belt-less shims tighter belt. NOTE: You want to have your belt as tight as possible without the bike creeping forward while in gear at idle.
