Bikeman Performance Goldstar Adjustable Clutch Weights for Yamaha Nytro and Viper 2008-2018 05-GSW-6070

Clutch weight tuning is one of the most effective ways to dial in your snowmobile's acceleration and mid-range responsiveness, but traditional fixed weights lock you into a single performance profile. The Bikeman Performance Goldstar Adjustable Clutch Weights give you the flexibility to fine-tune your primary clutch across a 60g–70g range without breaking out special tools or dealing with thread lock mess. Whether you're chasing better sled hook on hardpack or smoother engagement in variable snow conditions, these magnetically-retained weights let you optimize performance on the fly.

Built with an advanced ramp profile engineered for efficient power delivery, these weights transfer engine output to the track with measurable improvements in throttle response and acceleration feel. The integrated magnets handle all the holding force, so setup and adjustment become genuinely quick tasks—ideal for riders who like to experiment with different tune-ups between rides.
