Renthal Twinring Rear Sprocket Honda CRF450R / RX / WE
The Renthal Twinring Rear Sprocket is a durable off-road sprocket developed and tested over five years. Its flat-face two-piece design keeps weight low, maintains a narrow profile and improves long-term durability. The outer steel ring is expanded at 200°C, then fitted to the aluminum inner before cooling. This creates a permanent bond while flat socket set screws prevent lateral movement between the rings. Renthal chainwheels are used by more factory motocross and supercross teams than any other brand on the market. Each sprocket is CNC machined for excellent concentricity and an optimal tooth profile for extended service life in extreme conditions. This process allows Renthal to produce a lightweight rear sprocket that reduces rotating unsprung weight and helps transfer power efficiently to the rear wheel. The Renthal Twinring Rear Sprocket is built for serious MX and off-road riders who want durability and performance.
Features:
- Each Twinring sprocket that leaves Renthal's engineering facilities are individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit
- Inner ring of the Twinring is engineered from Ultralight 7075 T6 Aluminium which helps keep weight to a minimum
- Outer ring is constructed from electroless nickel coated steel which ensures an ultra long service life
- Mud grooves prevent build up of mud, helping to increase the working life of the sprocket
Note: Images are for reference only, actual sprocket will vary based on make and model.
