RK 520SO O-Ring Standard Duty Chains

RK 520SO  is a classic! The best choice if you are looking for an economical chain for motorcycle from 250cc to 400cc.

RK utilizes Nitrite Butadiene O-Rings to seal in lubrication and deliver smooth power with minimal loss of horsepower.

RK’s sealed-ring chains received the spotlight back in 1978 during Suzuka 8 hours endurance racing. While it was common for riders to change their non-sealed chains at least three times during the race. Racers riding with RK’s sealed chains achieved the win with only ONE chain!

Developed with Polaris ATV with Special Heat Treatment for Off-road Usage.
