FAQs
Is the Renthal Ultralight Sprocket suitable for all riding conditions?
The Ultralight sprocket is designed for performance in motocross and enduro. While durable, it may experience faster wear in extremely abrasive conditions (e.g., heavy mud, sand) compared to a steel sprocket. For purely longevity-focused applications in such environments, a steel sprocket might be considered.
How much weight does this sprocket save?
The Renthal Ultralight Rear Sprocket offers approximately a 66% weight saving compared to conventional steel sprockets.
What is the material used for this sprocket?
It is precision CNC machined from high strength 7075 T651 aluminium alloy.
Does this sprocket come with a chain?
No, this product is for the rear sprocket only. A compatible chain and front sprocket are required separately.
How often should I clean and lubricate my chain and sprockets?
For optimal performance and longevity, clean and lubricate your chain and sprockets after every ride, especially if exposed to dirt, mud, or water.
Can I mix and match Renthal sprockets with other brands?
While technically possible, it is highly recommended to use a complete Renthal drivetrain system (front and rear sprockets with a Renthal chain) for guaranteed compatibility, optimal performance, and maximum lifespan.
What does the '51T' in the product name refer to?
'51T' refers to the number of teeth on the sprocket, which is 51 in this case. This tooth count affects the gear ratio and can be chosen to optimize acceleration or top speed.
Troubleshooting
Chain skipping on sprocket
Check chain tension and sprocket wear. Ensure the sprocket is correctly aligned and securely fastened. Replace worn chain or sprocket.
Premature wear
Ensure proper chain lubrication and alignment. Riding conditions (e.g., excessive mud, sand) can accelerate wear. Consider using a steel sprocket for extreme conditions if longevity is paramount.
Noise from drivetrain
Inspect chain and sprockets for wear or damage. Ensure proper chain tension and lubrication. Check for any foreign objects interfering with the drivetrain.
