Improve Acceleration with Serpent 903645

Designed with racers in mind, the Serpent 903645 Aluminium 25T Centax Pinion Gear delivers consistent engagement and lower rotating mass. It pairs with Centax clutch systems to help sharpen throttle response and improve lap consistency.

Engineered Aluminium Advantage

Aluminium construction reduces inertia while keeping strength where it matters, supporting quicker acceleration and efficient top speed. The 25-tooth option provides a useful range for tuning gear ratios to suit different circuit conditions.

Built for Competitive Setups

Ideal for club and championship runners, the Serpent 903645 offers reliable meshing and straightforward installation with Centax clutch components. Use it when you want predictable drivetrain behavior under race loads.

Do I need to change my clutch to fit this pinion?

No clutch swap is usually necessary if your clutch is a Centax system; verify shaft and bell fitment before installation to be safe.

How does a 25T pinion affect gearing compared to 24T?

A single tooth change shifts the final drive noticeably; 25T will raise top speed slightly while altering acceleration characteristics, so test on track for best results.

Any tips for setting gear mesh?

Set a close but free mesh with minimal backlash, check under load, and recheck after a few runs as parts bed in to avoid premature tooth wear.

Should I lubricate the pinion?

Light protection like a dry film or small amount of gear grease on the spur interface can reduce wear, but avoid excess that attracts dirt.
