Good to know

Always use a master link with the same pitch and from the same series as the chain (same width, same seals). A master link goes on new: never reuse a clip that has already been taken off.

Fitting tips

1. Check that the master link pitch matches that of the chain.
2. On a sealed chain, place the supplied O-rings or X-rings on each side.
3. Clip-type link: fit the clip with its open end facing away from the chain's direction of rotation. Rivet-type link: rivet it with a suitable tool, without crushing the seals.
4. Spin the wheel and check that the link isn't stiff.

Why RENTHAL?

The Fatbar is made exclusively in the Renthal factory, from the brand's own 7010-T6 alloy: 28.6 mm at the clamps, 22.2 mm at the ends so you keep standard controls, and no crossbar. Its variable wall thickness saves weight and its shot-peened surface improves fatigue resistance, which counts when you're landing jump after jump.

Frequently asked questions

Clip or rivet?
A clip-type link is easy to fit and remove, ideal for motocross. A rivet-type link is more secure on big bikes and on heavily loaded sealed chains.
