RK Chain

Sealed chain solution for vintage motorcycles 


­The RK 530UWR chain is specifically designed for vintage motorcycles that originally came equipped with narrow-clearance, non-sealed 530-size chains. 


Leveraging RK's exclusive ultra-thin seal (UW-Ring) technology, the 530UWR achieves the durability of a sealed chain while maintaining a width comparable to a standard non-sealed chain - "making it the perfect upgrade without compromising fitment". 

Ideal for classic British bikes like Norton and Triumph, as well as Japanese vintage motorcycles from the 1970s and 1980s, the RK 530UWR is the "go-to choice for riders looking to enhance reliability while preserving authenticity." 


The chain features a silver coating on the inner and outer plates, pins, and rollers, offering excellent protection against rust and corrosion. 

By upgrading from a non-sealed to a sealed chain, riders can expect at least four times the chain life, along with significantly reduced adjustment requirements after the initial stretch of the chain.
