Renthal UltraLight Alloy Moto Rear Sprocket

The Renthal UltraLight Rear Sprocket is engineered to deliver maximum performance with minimum weight. Manufactured from high-strength 7075 T6 aluminium and CNC machined, it provides precise fitment, outstanding strength and efficient power transfer.

Maximum weight saving: Renthal UltraLight rear sprockets are up to 66% lighter than steel alternatives. This reduces both unsprung and rotating mass, helping to improve efficiency and power transfer.

CNC Machined for Maximum Precision

Each UltraLight rear sprocket is individually CNC machined at Renthal's engineering facilities in Manchester, UK. Extremely tight manufacturing tolerances ensure accurate and reliable fitment.

High-Strength 7075 T6 Aluminium

Renthal uses a specially enhanced 7075 T6 aluminium alloy that combines low weight with high strength and durability. The result is a lightweight rear sprocket capable of handling demanding motorcycle and racing applications.

Computer-Engineered Design

The sprocket geometry is computer engineered and tested to ensure precise fitment, excellent concentricity and effective load dispersion. The optimised tooth profile is designed to provide maximum and reliable power transfer.

Self-Cleaning Mud Grooves

UltraLight rear sprockets feature Renthal's self-cleaning Mud Grooves. This design helps prevent mud build-up between the teeth, reducing the conditions that can lead to accelerated wear of the chain and sprocket.
