This JT Sprockets Rubber Cushioned Steel Front Motorcycle Sprocket (MPN: 404.17RB, 17T) is for motorcycle riders seeking a smoother, quieter ride and extended drivetrain component life. Its key benefit is reducing noise and vibration through OEM-grade rubber cushioning, which also protects other parts and supports smoother gear shifts. A potential caveat is that it's designed to meet OEM specifications, so advanced performance tuning might require different gearing. This sprocket is precision machined from high-quality, heat-treated steel for durability and consistent performance, meeting or exceeding OEM standards.

The primary benefit is the reduction of noise and vibration by absorbing shock loads from chain movement. This also helps to protect drivetrain components and leads to smoother gear transitions.
This specific sprocket (MPN: 404.17RB) uses a 525 chain pitch and has 17 teeth. It is designed to meet OEM specifications for many Japanese motorcycles from the 1990s onwards. Always verify your motorcycle's original equipment specifications for chain pitch and tooth count before purchasing.
Front sprockets typically need replacement every 15,000-30,000 miles, but this can vary greatly depending on riding conditions, maintenance, and the quality of the sprocket. It's often recommended to replace the chain and rear sprocket at the same time for optimal performance and wear.
This sprocket is made from high-quality, heat-treated Japanese SCM420 chromoly steel alloy, known for its high wear resistance and durability.
No, this sprocket is designed to meet original equipment specifications and should serve as a direct replacement for your stock front sprocket without requiring modifications.
Clean the sprocket using a mild degreaser and brush. While the rubber is bonded, avoid harsh chemicals or high-pressure washing directly on the rubber inserts. Inspect the rubber for signs of damage or separation during regular maintenance.
A non-cushioned sprocket transmits power directly without any dampening. A rubber-cushioned sprocket incorporates rubber inserts to absorb shock, reducing noise, vibration, and wear on the drivetrain for a smoother, quieter ride.
Ensure the sprocket is correctly installed and tightened. Check that the chain is properly aligned and tensioned according to your motorcycle's service manual. Inspect the chain and other sprockets for wear, as worn components can cause noise even with a new front sprocket.
Verify that the sprocket is securely mounted and balanced. Check for any damage to the rubber cushioning. Ensure the chain is clean, lubricated, and correctly tensioned.
Confirm you are using the correct chain pitch (525 in this case) and that the chain is properly lubricated and maintained. Inspect for any foreign objects or debris that may be causing abrasion.
Ensure you are following the correct installation procedure for your specific motorcycle model. Double-check that the sprocket is oriented correctly and that no modifications are needed, as this sprocket is designed for OEM fitment.
Setup: This sprocket is designed to be a direct replacement for your motorcycle's stock front sprocket. Ensure your motorcycle is safely supported on a stand before beginning. Remove the chain guard and the countershaft sprocket nut. Slide off the old sprocket and install the new JT Sprockets sprocket, ensuring it is oriented correctly. Reinstall the countershaft sprocket nut and tighten it to the manufacturer's specified torque. Reinstall the chain guard. It is highly recommended to replace your chain and rear sprocket when replacing the front sprocket to ensure optimal performance and longevity of the new parts.
Compatibility: This specific sprocket (MPN: 404.17RB) is designed to fit motorcycle models using a 525 pitch chain and a 17-tooth front sprocket configuration, meeting OEM specifications for many Japanese motorcycle brands since the 1990s. Always confirm your motorcycle's original equipment specifications for chain pitch and tooth count before purchase.
Care: Regularly clean the sprocket with a mild degreaser and a brush to remove dirt and debris. Inspect the sprocket teeth for wear, and check the rubber cushioning for any signs of damage or separation. Lubricate your chain regularly according to your motorcycle manufacturer's recommendations. Proper chain maintenance will help maximize the life of the sprocket and the entire drivetrain.
