This Delrin motor pinion is an aftermarket replacement intended for Kyosho Mini Inferno models requiring a like-for-like motor pinion swap. The unit is supplied as a single 13T pinion for the motor position and is specified here as an upgrade part for routine maintenance and light tuning.
Delrin provides lower surface friction versus harder plastics and typically results in quieter gear engagement, aiding diagnostic checks and setup refinement. During installation, verify correct gear mesh and shaft alignment, confirm free manual rotation of the motor, and perform a controlled power test to validate smooth operation.
Recommended for hobbyists seeking a reliable, low-noise pinion option for Mini Inferno gearsets, this Delrin 13T helps preserve predictable engagement and supports basic drivetrain upkeep.
