Twinring®

Renthal Twinring benefit from over 50 years of motocross rear sprocket manufacturing expertise and the help of our top Off-Road and Enduro factory race teams, Renthal has developed the ultimate dirt bike rear sprocket for those looking to ride more and work less.

The unique, dual-material design combines a hardened steel outer chain ring that is heated to 200°C before being perminantly fitted to our Ultralight aluminum inner, creating a permanent bond for the life of the sprocket. The result is a lightweight, long-wearing rear sprocket fit to tackle any condition you can find, without adding unnecessary unsprung weight and compromising power delivery.

For the best way to find the correct chainwheel for your motorcycle, use our Fit My Bike Parts Finder.

Installation Instructions

The inner ring of the unique Renthal® Twinring® is engineered from Ultralight 7075 T6 Aluminium. This keeps the weight of the Twinring® to a minimum.

Renthal® Twinring® feature a Electroless Nickel Plated steel. This ensures an ultra long service life of the chainwheel, providing you with maximum power transfer longer than ever.

Each Twinring® that leaves Renthal's engineering facilities in the UK is individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit.

The Outer ring is expanded to 200°C to be fitted to the inner ring. Cooling creates a permenant bond. Flat socket set screws prevent lateral movement between the rings in high velocity impacts.

Twinring® feature Renthal's self cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components.

Twinring is available in 6 colours to help you personalise your setup.

The available colours are Black, Blue, Red, Green, Orange and Tanium.

The anodised surface finish provides an integral coating preventing corrosion. A 15 step process is carefully carried on on each chainwheel individually.
