Race-Ready Pinion from Serpent

The Serpent 903801 Centax 20-tooth gear-pinion is an aluminium upgrade matched to the XLI Gen2 clutch system. Its construction focuses on reliable tooth engagement and reduced rotating mass, giving smoother drivetrain response. Suited to track use, it provides a dependable replacement for worn or stock pinions.

How does a 20T pinion affect gearing?

Tooth count alters final ratio versus the spur gear. Swapping to a 20T will change rev response and top speed depending on your spur and tyre size.

Is aluminium better than steel for pinions?

Aluminium saves weight and resists corrosion, though it can show wear faster than hardened steel. For many racers the balance of weight and durability is worth it.

Any setup advice for XLI Gen2 installs?

Check shaft alignment, confirm spur clearance, and run a short test at low load to verify smooth engagement before racing.
