Optimize Your Gearing with Sunstar

The Sunstar 43T-520 Aluminum Rear Sprocket is the perfect choice for riders looking to improve their motorcycle's acceleration and overall drivetrain efficiency. By utilizing a 43-tooth configuration, this sprocket allows for a shorter gear ratio, providing quicker off-the-line performance and improved mid-range pull. Crafted from premium-grade aluminum, it offers the ideal balance of strength and weight reduction, making it a staple for both competitive racing and performance-oriented street riding.

Performance Advantages

  • Enhanced Acceleration: The 43T count is ideal for riders seeking improved torque and throttle response.
  • Durable Aluminum Alloy: Engineered for maximum durability without the heavy weight of steel alternatives.
  • Precision Machining: CNC-cut teeth ensure smooth power delivery and reduced chain noise.
  • Universal Fitment: Designed for seamless integration with various Suzuki and Yamaha models using a 520 chain setup.

Every Sunstar sprocket undergoes rigorous quality control to ensure it meets the demands of high-speed racing environments.
