The Serpent 904103 19T pinion is produced to enhance drivetrain stability on the 966-E chassis. Its accurate tooth form promotes consistent engagement and helps reduce premature wear during regular running.
The 19T layout gives a practical mix of torque and top-end speed, making it suitable for drivers who need controllable acceleration across mixed surfaces.
This pinion is compatible with standard 966-E configurations, offering an easy swap for maintenance or gearing adjustments. Always verify mesh spacing and motor clearance after installation.
