Chain EK RRSM

Narrow Racing Chain
EK’s Road Race / Supermoto chain is the most narrow 520 pitch chain on the market. When you’re serious about racing, this chain provides the lightest weight possible without compromising strength and dependability. Also available unsealed in 415 pitch for smaller applications.

EK’s SX-Ring is an even slimmer profile racing specified seal utlising the same ‘X’ style design that provides 40% less friction than a normal O-ring seal. Combining this with the extra low profile allows this seal to achieve the best wear to use ratio of any QX-Ring option. This seal is exclusive to EK’s narrow racing chain line ‘RR/RRSM’.

JT Self-Cleaning Steel Front Sprocket

MX-series steel front sprockets are manufactured to exacting tolerances and designed with special self-cleaning grooves for added life and performance. Made from the best chromoly steel and fully heat-treated for maximum durability, the MX range of front sprockets are designed for champions.

Supersprox Stealth Rear Sprocket

Supersprox Stealth Bi-Metal Rear Sprockets feature a patented combination of steel teeth and an aluminum core. This design delivers 3× the lifespan of aluminum sprockets while being up to 30% lighter than all-steel alternatives. By reducing friction, they extend chain kit longevity, enhance bike performance and appearance, and are available in various colors to fit 99% of street and off-road motorcycles.
