Fine Tune the Viper 988E with a 21T Pinion

The Serpent SER904176 21T pinion is intended as a maintenance or upgrade item for the Viper 988E. Its profile is crafted to sit correctly in the Viper drivetrain and support consistent power transfer during use.

Accurate Tooth Profile for Better Response

With an engineered tooth profile, this 21T pinion helps maintain predictable throttle feel in electric Viper 988E setups. Regular checks keep the mesh steady and the drive smooth.

Fitment Tips and Routine Checks

Installation is straightforward on the Viper 988E when you verify shaft fit and alignment. After fitting, confirm gear mesh and secure fastenings to avoid movement under load.

Will this change my gearing feel?

Using the Serpent SER904176 21T keeps the same tooth count on the pinion; changes in feel come from spur size or motor tuning. As a like-for-like part, it should maintain the expected drive characteristics.

Do I need special tools to fit it?

Basic hand tools are sufficient: hex drivers and a small spanner to secure the motor. A clear view of the mesh and a marker for checking wear are helpful during setup.

How do I check for correct mesh?

Push the gear into position, rotate the spur by hand and look for slight clearance between mating teeth. Adjust until the teeth seat properly but are not binding, then retighten and test at low speed.
