Sport bike chain
High quality replacement chain for most sport bikes 400cc and lower. Great application for a 250cc or 300cc sport bike. Installed into 2020 Yamaha r3.

A Superior Upgrade
This RK Racing Chain is an excellent product from a top-tier brand. Unlike the original equipment manufacturer (OEM) chain on my motorcycle, which stretched and required frequent adjustments, this chain has held up perfectly. The 520-SO series uses traditional O-rings to seal in lubricant, which keeps the chain running smoothly and significantly reduces maintenance. The result is a much safer and more effective chain with very little slack or wear, even after extensive use. I am absolutely pleased with this chain and its performance. It’s a durable, long-lasting product that makes a noticeable difference and provides peace of mind on the road.

Great Products- Great Value
RK Racing speaks for itself at any level. They've stood the test of time and still offer significant value. Chains and sprockets are their main game and have been for decades. I got a great deal on this chain! It's stood the test on my RMZ250 through the peak heat of a southern Summer beating.
