Serpent 903199 Centax Flyweights PTFE .21 Off-Road Upgrade  [SER903199]

Upgraded Centax Flyweights for Stronger Clutch Pickup

These Serpent 903199 Centax Flyweights are machined for use with .21 engines and replace standard molded weights. The precision process and composite materials provide a tougher, more stable flyweight option.

Built from Denser Composite Material

Machining from solid stock and incorporating carbon and graphite yields a denser, harder component than injection molded parts. That extra hardness helps reduce wear and maintains steady performance across runs.

Adjustable and More Aggressive Engagement

The profile of the weights promotes outward movement for a sharper clutch engagement. A secondary hole is provided for a grub screw so you can tweak the engagement level to match tyre, track and engine characteristics.
