Moturo 15mm CNC Chain Tensioners for Pit Bike, Dirt Bike, and ATV

The Moturo 15mm CNC chain tensioners for your dirt bike, pit bike, or ATV — the standard components for perfect tension at the rear wheel after every chain change. CNC-machined aluminum, ready to install.

The tensioners sit on the swingarm and set the exact distance to the sprocket. Both are guided via the swingarm axle and clamped with the axle nut.

CNC-machined aluminum, chain alignment adjustable in increments. The geometry follows the standard used on most pit bike, dirt bike, and ATV swingarms.

Replacement takes about half an hour with an Allen key set and a socket wrench for the axle nut.
