Moturo chain tensioner 15mm blue for dirt bike

Moturo CNC Chain Adjuster 15mm blue for Dirt Bike

The Moturo CNC chain adjuster 15mm blue for your dirt bike, pit bike or mini bike — a component that should be replaced when changing the chain. CNC machined, 15 mm axle dimension, ready to install.

The chain adjuster sits on the rear swingarm of your dirt bike or pit bike and adjusts the chain tension via the 15 mm axle dimension. CNC machined, blue, with markings for reproducible tensioning on both sides of the swingarm. Universal design for common swingarms with 15 mm axle diameter and standard adjuster guides.

Important before installation: Measure the axle diameter on your own bike — 15 mm must be a match. Also compare the swingarm design and the hole pattern of the adjuster guide slot.

Replacement takes about half an hour with a socket wrench set and torque wrench.
