The Renthal 490U-525-44P-HA is an Ultralight aluminum rear chainwheel designed for road, road racing, offroad, and kart applications. Precision CNC machined from specially enhanced 7075 T6 aluminum alloy, this sprocket delivers unmatched accuracy of fit, tooth profile, and concentricity for maximum power transfer and long service life.

Key Features:

• 525 pitch, 44-tooth rear sprocket — fits a wide range of sport and performance motorcycles
• CNC machined to extremely tight tolerances for precise fitment, concentricity, and optimal load dispersion
• Ultralight design — 66% lighter than steel — minimizes unsprung revolving mass at the rear wheel for improved handling and maximum power transfer
• Advanced tooth profile allows the chain to roll smoothly on and off the sprocket, reducing wear and noise while improving efficiency
• Machined self-cleaning grooves at each tooth help increase wear resistance
• Hard anodized finish — an integral surface coating that significantly increases surface hardness and wear resistance for extended longevity
• Suitable for road, road racing, offroad, and kart use

Renthal Ultralight chainwheels are trusted by factory race teams across World Superbike, National Superbike, Motocross, and Supercross paddocks worldwide. The combination of high-strength 7075 T6 alloy and hard anodizing delivers a rear sprocket that is both race-proven and durable enough for street and track day use.
