KTM 450XC-F 2020 - 2021 Renthal Silver Twinring 52t Rear Sprocket Aluminium/Steel Combo

Renthal Twinring Rear Sprockets

• Renthal Twinring benefit from over 50 years of motocross rear sprocket manufacturing expertise and the help of the 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 degrees 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.
• 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 degrees 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.
