Renthal Ultralight Hard Anodised Rear Sprocket 520 - Kawasaki

Upgrade to championship-proven performance with the Renthal Ultralight Hard Anodised Rear Sprocket - precision-engineered for road and road racing applications on Kawasaki motorcycles. Trusted by riders across New Zealand who demand the perfect balance of lightweight performance and exceptional durability, this premium sprocket combines race-winning technology with extended service life.

Why Choose Renthal Hard Anodised Sprockets?

Renthal hard anodised sprockets are specifically designed for road and road racing applications, featuring all the benefits of Renthal's legendary off-road aluminium rear sprockets but with significantly increased longevity from the hard anodising process. Hard anodising is an integral surface coating that dramatically increases the hardness and wear resistance of the chainwheel surface, delivering the durability you need for New Zealand's demanding riding conditions.

Premium Construction and Engineering

Precision CNC manufactured to extremely high tolerances, Renthal hard anodised rear sprockets are crafted from high-strength 7075 T6 aluminium alloy - the same aerospace-grade material used in aircraft construction. The ultra-hardwearing hard anodised finish provides extreme mileage capability while maintaining the lightweight performance advantages that Renthal is famous for.

Performance Benefits

The computer-aided design delivers maximum reduction of unsprung weight at the rear wheel, ensuring optimal power transfer and improved handling response. At 33% lighter than steel, the Renthal rear sprocket reduces rotational mass for quicker acceleration and more responsive braking. The self-cleaning mud grooves prevent dirt buildup and help keep the sprocket clean, extending both chain and sprocket life.

Hard Anodising Technology

The hard anodising process creates an integral surface coating that significantly increases hardness and wear resistance. Unlike standard anodising, hard anodising penetrates deep into the aluminium surface, creating a durable, wear-resistant layer that extends sprocket life far beyond standard aluminium sprockets while maintaining the lightweight performance advantage.
