EK 520RRSM

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’.
