Product OverviewOEM Verified Specifications

Precision-machined 520-50T rear sprocket engineered for the 2026 Ducati Desmo450 MX platform. This silver-finished component utilizes a grooved tooth profile specifically designed to maximize chain engagement and minimize lateral slippage during high-torque acceleration phases. As a critical drivetrain element for the Desmo450, the 50-tooth configuration is calibrated to optimize the final drive ratio, ensuring that the motorcycle’s power delivery remains linear and responsive across the entire RPM band required for competitive motocross racing. The silver finish indicates a robust surface treatment that resists corrosion and wear, maintaining the structural integrity of the teeth even under the abrasive conditions of off-road competition.

Optimized tooth geometry for superior chain tracking and reduced drivetrain friction. The specific contouring of the grooves ensures that the 520-series chain seats perfectly within the sprocket’s pitch, reducing the risk of chain jump and premature wear on both the chain rollers and the sprocket teeth. This precise alignment is vital for maintaining consistent power transfer from the engine to the rear wheel, allowing the rider to modulate throttle inputs with absolute confidence. By minimizing mechanical losses in the final drive, this sprocket contributes to a more direct and immediate response to rider inputs, enhancing the overall control feel of the Desmo450 during technical cornering and rapid direction changes.

Rugged construction designed to withstand the extreme impact loads and debris exposure of professional motocross. The rear sprocket is built to endure the constant shock loads generated by landing from jumps and navigating rough terrain, where the drivetrain is subjected to sudden torque spikes and reverse forces. Its durable material composition ensures resistance to deformation and cracking, providing a reliable interface between the chain and the rear axle. This component is essential for maintaining the structural coherence of the rear end, ensuring that the drive system remains secure and functional throughout the rigors of a full race day, thereby supporting the overall durability and performance consistency of the motorcycle.
