Introducing the Motorex MO3150638, a premium quality all-carb sprocket specifically designed for Yamaha SL, SR, GP, and GS motorcycles manufactured between 1971 and 1976. This sprocket is an essential component of the drive system, responsible for transmitting power from the engine to the rear wheel.

Crafted from high-strength steel, this Motorex sprocket boasts exceptional durability and resistance to wear and tear. Its precise machining ensures a perfect fitment and smooth running, reducing the risk of vibrations and undue stress on other components.

This sprocket is also meticulously finished with a durable, corrosion-resistant coating. This coating not only provides an aesthetically pleasing appearance but also protects the sprocket from the elements, ensuring that it maintains its functionality and longevity even in harsh conditions.

When it comes to replacing your motorcycle's drive sprocket, trust Motorex to deliver a top-tier component that not only meets but exceeds your expectations in terms of quality, fitment, and performance. The Motorex MO3150638 is your reliable partner for ensuring the optimal functioning of your classic Yamaha SL, SR, GP, or GS motorcycle.
