The Serpent 120167 Motor-pinion uses solid aluminum construction to provide a reliable, low-mass gear for demanding use. The 48P 29T layout is aimed at riders who need dependable engagement across varied surfaces.
Aluminum reduces rotating inertia while offering good resistance to impact and wear. That helps the pinion keep a steady mesh even when driving on rough or loose terrain.
The 48 pitch with 29 teeth matches compatible spur gears precisely, which minimises uneven wear and keeps the drivetrain running efficiently under load.
This pinion suits a broad selection of 1/10 scale electric models, so it is useful for replacing worn parts or testing alternate gear ratios to tune acceleration and top speed.
