About this product
Upgrade your motorcycle's drivetrain with the Sunstar Works Z Steel Rear Sprocket. This high-performance sprocket is engineered for superior durability, strength, and self-cleaning capabilities, ensuring a longer lifespan for your entire chain drive system. Ideal for off-road enthusiasts and professional riders alike, the Works Z sprocket provides unmatched reliability in even the most challenging conditions.
Description
The Sunstar Works Z Steel Rear Sprocket is constructed from the highest-quality stainless steel and undergoes a 100% heat-treating process. This provides the ultimate combination of strength and durability. The electro-less nickel plating not only provides a stylish brushed/natural stainless steel appearance, but also enhances corrosion resistance without compromising performance. Its unique offset tooth design offers exceptional self-cleaning capabilities, efficiently removing mud and dirt to extend the life of your chain drive. Up to 50% lighter than OEM steel sprockets (depending on the application and number of teeth), this sprocket offers improved performance without sacrificing strength. Boasting twice the hardness of standard steel and 20% greater lateral strength, it provides up to three times the overall life. Compared to aluminum, it delivers five times the hardness and durability, offering up to 10 times the overall life. This sprocket is trusted and used by top teams and riders in GNCC, WORCS, and motocross.
