EVO Powersports Kawasaki Teryx H2 TAPP Secondary Clutch
Kawasaki gave the SXS community a great vehicle with a mediocre secondary clutch with many inherent problems that translate into poor performance and very high belt temperatures. The EVP TAPP secondary solves all the issues present in the OEM clutch!
The OEM secondary clutch uses an extremely steep helix with a massive spring to control belt tension. The EVP TAPP secondary uses the proper dual angle helix along with an adjustable torsional/compression style spring. The helix ramps are easily replaced to fine tune the clutch shift characteristics if needed, whereas the OEM clutch has no provision for changing the helix angle.
The OEM secondary has no cooling fins whatsoever and has an enclosed steel helix/shaft that builds heat and transfers it to the belt. TAPP has cooling fins machined into the sheaves along with an open helix/spring combination made from aluminum, which efficiently dissipates heat and keeps the belt cooler.
Lastly, the OEM secondary contains grease inside of the spring/helix assembly. This leaks out and is flung onto the belt/primary clutch and clutch cover when hot. Grease and CVT systems are not compatible.
The EVP TAPP secondary clutch, alone with no other changes, demonstrated a vast improvement in shift characteristics, belt temperature, and life over stock. EVP TAPP secondary, EVP primary clutch weight kit, and the EVP Worlds Best Belt are the ultimate in shift characteristics, getting power to the ground and extending belt life.
Features
- Oversize Helix Diameter: Maximizes the clamping force on the belt. One of the largest issues with existing designs is that a small hub limits both the spring coil diameter as well as the maximum force the helix can apply to the belt. Big horsepower cars no longer have to run a double spring.
- Larger Helix Surface: Allows the use of wider rollers that can better distribute the tremendous loads they experience. This is especially true under drag race conditions. We are happy to report that we have put hundreds of runs on a set of rollers with full on 5000 RPM high boost launches. These drag race launches will damage or destroy all other clutch rollers within a few runs.
- Replaceable Helix Ramps: TAPP engineered an elegant solution so only parts of the helix ramps need to be changed when you want to change helix angles.
- Torsionally Adjustable Spring Tension: The design utilizes a torsional style helix cap with adjustable slots which allow the spring torsional tension to be used as a tuning feature.
- Unmatched Performance: All of these design features add up to power, performance and longer belt life. At the 400 wheel horsepower level, just by changing to the TAPP secondary we were able to get another 15-20 horsepower to the wheels. Whether you are trail riding, dunning or racing, belt life will be extended when using a properly calibrated TAPP Clutch.
