Renthal Twinring™ Rear Sprocket 1540-520-49GPBK - Honda 1984-2026
Product Description
Maximize your Honda's final drive durability without adding unnecessary weight with the Renthal Twinring™ Rear Sprocket. Engineered for riders who demand longevity from their drivetrain, this 49-tooth black sprocket combines a lightweight aluminum core with a hardened outer steel ring to withstand the harshest track and trail environments.
Utilizing an innovative dual-material construction, the inner ring features high-strength Ultralight™ 7075 T-6 aluminum to reduce unsprung mass, while the electro-less nickel-coated steel outer ring offers ultimate wear resistance against high-torque loads.
Top Features: Renthal Twinring Rear Sprocket
- Inner ring is crafted from high-strength Ultralight™ 7075 T-6 aluminum to match standard Renthal weight-saving specs
- Outer ring features an electro-less nickel-coated steel build designed with minimal material to keep rotating weight down
- Permanent interference fit created by expanding the outer ring at 200°C over the inner ring with a wave pattern
- Flat socket head screws provide additional structural strength during severe side impacts and eliminate chain guide contact
- Self-cleaning mud grooves integrated between each tooth prevent dirt buildup to reduce wear and weight

Frequently Asked Questions
Q: What materials are used to construct this Twinring sprocket?
A: It uses an inner ring made of Ultralight 7075 T-6 aluminum paired with an outer ring made of electro-less nickel-coated steel.
Q: How long does a Twinring sprocket last compared to standard aluminum options?
A: It is designed to outlast a standard all-aluminum sprocket by up to 3 times while remaining much lighter than a full steel rear sprocket.
Expert Pro-Tip: When installing the Renthal Twinring sprocket, ensure the flat socket head screws are torqued evenly to specification. The high-interference thermal fit creates a permanent bond, so keeping your chain properly aligned and adjusted will maximize the lifespan of both the outer steel teeth and your drive chain.
