Review: 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.
Review: 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.
