AFAM offers this 520XRR3 chain kit in a 14-48 configuration designed for off-road riding, where the drive ratio must remain constant despite the extreme stresses yourBETA RR 300cc endures. It is designed for riders seeking a more responsive engine thanks to a gear ratio that enhances acceleration and responsiveness at low RPMs. The reinforced X-Ring chain ensures excellent internal sealing and minimizes lubrication loss, which helps reduce wear over the long term. The steel sprocket guarantees high resistance to impacts and the heavy stresses associated with repeated acceleration. The ultra-light, mud-resistant aluminum sprocket reduces rotating mass while limiting dirt buildup in challenging conditions. The set offers a smoother, lighter, and more durable drivetrain, ideal for optimizing performance under heavy use.
