RK BL420MRU SEALED LIGHTWEIGHT PERFORMANCE CHAIN
Lightweight, low friction, sealed, U-Ring 420 pitch chain perfect for Honda® Monkey and Honda® Grom.
MRU features RK’s proprietary Ultra Thin Seal, U-Rings, where the thickness of the seal is less than 50% of the most common O-ring seal. This allows RK to design a Sealed Chain with the weight of a Non-Sealed Chain. MRU will feature 4 times longer chain life than comparable non-sealed 420 chains and will require less chain adjustments compared to non-sealed 420 chains.
