Yamaha Team Secondary Clutch

 Mountain Performance and Team Industries joined together to offer this exciting new TSS-98 Snowmobile Secondary Clutch for Yamaha application. The TEAM® Rapid Reaction™ clutch eliminates binding observed in other clutches by the separation of the alignment function from the activation function. Close tolerance machining and select materials provide a secondary clutch that runs cooler and more efficient. The clutch is built with tighter clearances yielding longer life. This new technology has been successful in the racing and performance markets, and is superior at delivering power. Features include Twin enclosed rollers and a Twin Trax™helix; the helix is actually two helixes in one. Each helix includes two different angle combinations. Select a steeper angle for those hard pack days and a shallower angle for the deep powder days. The features result in 1) Smooth, consistent up shift and back shift, 2) proved efficiency, performance, and durability, 3) Tunable with cam angles and springs, and 4) Extended belt life. All the tuning has been done. MPI spent last year tuning this clutch system for optimum Yamaha performance through all conditions imaginable. The result is a tailored setup to fit your exact needs. 

To match the unique design, a new type of multi-angle helix has been developed: The 1/2 progressive: Example a 50/40 1/2 progressive starts at 50deg and falls to 40deg; but unlike other multi-angle helixes is hits its finish angle 1/2 way through the shift and them acts like a straight angle through the remainder of he shift. Over 100 Helix Angles Already Exist. That's 50 helixes with 2 cuts on each helix - most popular listed:
