About the Chain:
Featuring RK's Ultra Thin Seal technology, the seal thickness of the MXU series UW-rings are less than 50% of the common seal. Made for professional enduro/motocross racers. The UW-rings significantly improve chain life by lowering friction over your conventional heavy duty chain, while the ultra thin seals reduce weight compared to a O or X-ring chain.
