Product Info

If you’re pushing real power through your drivetrain or absolutely thrashing your bike on a moto track, the last thing you want is a weak link hiding behind your sprocket. This billet cover might look like a cosmetic upgrade... It’s not.

Designed with integrated cooling fins to help manage gearbox fluid temps and slightly increase oil capacity, this cover adds real function where it counts. But the real story is strength.

During load testing, this cover withstood over 13,000 lbs of force before reaching distortion. For reference, a typical 520 chain has an ultimate tensile strength of around 6,000–9,000 lbs, and its real-world fatigue limit is much lower.

Translation:
If something gives under extreme load, the chain likely fails before this cover even thinks about bending.

In real riding, shock loads from hard landings and aggressive throttle spikes push the chain closer to its snap point. This cover stays below its bending threshold. Exactly how it should be.
