Product Description
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 Sidewinder 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.
This specific helix is Dalton model # YSR 37/35
