AFAM offers this 520XRR3 chain kit in a 13-49 configuration, designed for off-road riding where the reliability of your BETA RR 300cc’s drivetrain is essential. It is intended for riders seeking a balance between responsive acceleration and mechanical durability on demanding terrain. The reinforced X-Ring chain ensures excellent internal lubrication retention, which reduces wear and maintains performance over time. The steel sprocket and ultra-light aluminum chainring reduce rotating mass while maintaining the strength required for the demands of motocross and enduro. The sprocket’s anti-mud coating helps shed dirt, ensuring a cleaner and smoother power delivery even in difficult conditions. Together, these features help optimize engine response and extend the kit’s service life under intensive use.
