RK 420MRU U-Ring Chain

The 420MRU U-Ring Chain is meticulously engineered for Honda Monkey and Grom motorcycles, incorporating RK's exclusive Ultra Thin Seal U-Rings.

This innovation not only trims down the weight but significantly extends the lifespan of the chain, promising up to four times the durability of similar non-sealed chains. With reduced maintenance and fewer adjustments needed, riders enjoy more time cruising and less time tinkering in the garage.

Features:

  • RK's exclusive Ultra Thin Seal U-Ring design
  • Seal thickness is less than 50% of the most common O-ring seal
  • Lightweight for small displacement applications
  • Includes clip type master link
