Manufacturer reference: 4692 51 C45
The PBR ultra-light steel C45 4692 sprocket in 520 pitch is designed for motocross riders who want a reliable transmission without adding weight to the rear of the machine. Designed to fit a 520 chain, this 51-tooth sprocket features a steel construction (black finish) and a lightweight design intended to withstand the demands of off-road riding while minimizing unsprung mass.
Ideal for motocross, this sprocket naturally fits machines like the KAWASAKI KX 450 (2026), the SUZUKI RM-Z 250 (2006), or the KAWASAKI KX 450 X (2024). It is used as a standard replacement to achieve neutral engine behavior or to fine-tune the final ratio according to the terrain and riding style. Easy installation, standard maintenance (tension and lubrication of the chain): the PBR 4692 sprocket focuses on robustness and compactness, designed to withstand shocks, mud, and intensive track sessions.
