Renthal TwinRing Rear Sprocket Pitch Tooth Sprockets

The Renthal TwinRing rear sprocket is a two-piece dirt bike and off-road motorcycle rear sprocket (chainwheel). Renthal developed it for motocross and enduro riders who want long service life without the weight of a full steel sprocket.

Key Features:

• Dual-material construction: a lightweight Ultralight 7075 T6 aluminum inner ring is paired with an electroless nickel coated steel outer ring.
• Permanent bond: the steel outer ring is heated to 200°C and fitted over the aluminum inner. The interference fit forms a lasting bond, and flat socket head screws help prevent movement between the rings.
• Long wear life: the steel tooth section is built for durability. Renthal states it outlasts a standard aluminum sprocket several times over, at a much lower weight than an all-steel sprocket.
• Flat-face, narrow profile: the design keeps weight down and stays about as narrow as a conventional sprocket. The flat socket head screws also help protect against side impacts.
• Self-cleaning mud grooves: grooves between the teeth help prevent dirt and mud build-up, which reduces chain and sprocket wear.
• Precision CNC machined: each sprocket is machined to tight tolerances for an accurate fit.
• Made in the UK by Renthal, which has more than 50 years of experience making motocross sprockets.

It is a direct replacement for the stock rear sprocket. Several tooth counts and finishes are available, so choose the option that matches your gearing needs.
