FAQs
What is the chain pitch for this sprocket?
This Renthal Ultralight Rear Sprocket is designed for a 520 chain pitch.
How do I know if this sprocket fits my bike?
Refer to the 'Compatibility' section in the product description for a list of compatible Husqvarna, Gas-Gas, Sherco, and Beta models. Always double-check your motorcycle's specific make, model, and year.
What does 'Ultralight' mean for performance?
The 'Ultralight' designation refers to a significantly reduced weight compared to standard sprockets. This lessens rotational mass, which can improve acceleration and make the bike feel more agile.
Is this sprocket suitable for street use?
This sprocket is primarily designed and recommended for motocross and enduro (off-road) applications. Its gearing and design may not be optimal or durable for street riding.
How often should I replace my rear sprocket?
Sprocket replacement intervals vary based on riding conditions, maintenance, and material. Inspect your sprocket regularly for hooked or uneven teeth. A common recommendation is to replace the sprocket and chain together when either shows significant wear.
Can I mix this sprocket with a different brand of chain?
While it's possible, it's generally recommended to use a chain that is designed to work with the sprocket's pitch (520) and is of good quality. Using mismatched components can sometimes lead to faster wear or suboptimal performance.
What is the warranty on Renthal sprockets?
Renthal typically offers a limited warranty against manufacturing defects. Specific warranty details should be confirmed with the retailer or Renthal directly, as it pertains to material and workmanship, not normal wear and tear.
Troubleshooting
Chain skipping or noisy operation
Check chain tension – it should be neither too tight nor too loose as per your motorcycle's manual. Inspect chain and sprocket for excessive wear or damage. Ensure the sprocket is correctly installed and all mounting bolts are tight.
Sprocket does not fit hub correctly
Verify that you have the correct sprocket model and tooth count for your specific motorcycle model. Ensure no debris is present on the hub or sprocket mounting surface.
Premature wear on sprocket or chain
Ensure proper chain lubrication and regular cleaning. Check for alignment issues between the front and rear sprockets. Avoid aggressive riding without proper drivetrain maintenance.

Setup, Compatibility & Care
Compatibility: This sprocket uses a 520 chain pitch and is designed for specific Husqvarna, Gas-Gas, Sherco, and Beta models listed in the product details. Always verify your motorcycle's make, model, and year against the compatibility list before purchasing.
Setup: Installation requires removing the rear wheel and old sprocket. The new sprocket should be mounted using the appropriate hardware, ensuring it is seated correctly against the hub. It is crucial to use a new or properly inspected chain and to set the chain tension according to your motorcycle manufacturer's specifications. Professional installation is recommended if you are unfamiliar with drivetrain maintenance.
Care: Regularly clean the sprocket and chain with a suitable degreaser and brush. Inspect the sprocket teeth for wear patterns (hooking or unevenness) and the chain for stretching. Lubricate the chain after cleaning and before each ride. A clean, well-lubricated, and properly tensioned drivetrain will maximize the life of the sprocket and ensure optimal performance.
