Primary Drive Clutch
All new design for the New 4 Cylinder Engines
The design is similar to our HD clutches from other machines that offer a spread cam arm pin diameter. This allows for more leverage through the cam arms.
This clutch also incorporates a lager diameter 2 way bearing design for longer lifespan through use and smoother take off.
With a mild tune on a 4 seat machine we have seen top end speeds 118+ MPH with both STM primary and secondary together
Secondary Driven Clutch
This is an allbillet construction and capable of using compression springs with different spring rate options available. We havemanyhelix angles seemenu for available options. We can also provide custom helix angles if you desire for an additional fee.
Comes with bolt for installation.
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.
Choose a helix angle– The most popular helix is the 35/40ºP. It is a good all-around helix. We found that is worked the best for the average to aggressive trail rider.
Choose a spring– The most popular spring is the KSS8 lime green. This spring works well for most average to aggressive trail/dune riders.
KEEP IN MIND WE CAN ONLY GET YOU CLOSE WITH SET UP.Everyone’s riding style is different so it’s up to the customer to do the fine tuning!
