Serpent 903199 Centax Flyweights PTFE .21 Race-Focused Set  [SER903199]

Machined Flyweights for Predictable Clutch Performance

The Serpent 903199 Centax Flyweights are tailored for .21 powerplants and produced with precision machining. Switching from injection molded parts to these machined weights yields more uniform behaviour lap after lap.

Engineered Hardness and Density

By machining from solid material and using carbon and graphite elements, these flyweights achieve a greater hardness and density than molded alternatives. That toughness helps them resist wear and keeps engagement consistent under race conditions.

Customisable Clutch Bite

These flyweights are designed to drive outward for a crisper clutch pickup. Each weight includes an extra hole for fitting a grub screw so drivers can dial in the level of clutch aggression to suit track and tyre grip.
