DALTON DALTON REVERSE HELIX FOR YAMAHA 472YSR3539 YSR 35_39

2017+ Yamaha Sidewinder Roller Secondary – YSR Series

The 2017+ Yamaha Sidewinder model comes with a roller secondary. The roller secondary clutch is different than other previous Yamaha models with button secondary, and uses a different helix. We have a wide selection of angles available for tuning. The stock helix when with the stock secondary spring on a Sidewider is close to coil bind (very close to being stacked coil to coil when at full shift of the clutches). Dalton helixes now have more relief depth in the spring pocket for those concerned with that.

Dalton helixes feature solid billet construction, accurate machining and angles the same as Yamaha.

All Dalton roller helixes for this clutch use the “YSR” designation. A single number indicates a straight angle; multiple numbers identify the curve from the start angle to the finish angle, e.g. (YSR-32 / 36).
