FAQs
Does changing to a 51T sprocket affect my top speed?
Yes, increasing the tooth count on a rear sprocket typically improves acceleration but will result in a lower top speed and higher engine RPMs at highway speeds.
Do I need to replace my chain when installing this sprocket?
If you are changing the gear ratio (changing the tooth count significantly), it is highly recommended to check if your current chain length is adequate or if a new chain is required.
How often should I inspect the sprocket teeth?
Inspect for wear every time you perform routine chain maintenance or at least every 500-1,000 miles, looking for hooked or sharpened teeth.
Can I use this sprocket on both off-road and street bikes?
Yes, the JT Steel Sprocket is designed to handle the stresses of both environments due to its durable heat-treated construction.
Is any special hardware required for installation?
No, it is designed to fit your motorcycle's OEM mounting points, but it is always good practice to use thread-locking compound on the sprocket bolts.
Troubleshooting
Increased noise during operation
Check chain tension and ensure the chain is properly lubricated; also verify that the sprocket is aligned correctly with the front sprocket.
Chain slipping or jumping teeth
This is often a sign of an excessively worn chain; replace both the sprocket and the chain as a set.
Vibration at high speeds
Confirm that all mounting bolts are tightened to the correct manufacturer torque specifications and that the sprocket is seated flush against the hub.
Pros and Cons
Pros
- Superior wear resistance compared to aluminum alternatives
- Computer-optimized design minimizes weight without sacrificing strength
- Excellent value for money regarding longevity
- Heat-treated for maximum tooth durability
Cons
- Heavier than aluminum or specialized alloy sprockets
- Higher tooth count may require a longer drive chain
- Changes in gear ratio can alter speedometer accuracy
Setup, Compatibility & Care
Before installation, ensure your motorcycle's chain is in good condition; pairing a new sprocket with a worn chain can result in premature wear for both components. To install, remove the rear wheel and old sprocket, ensuring the hub contact surface is clean of debris and old grease. Align the new sprocket with the mounting holes and tighten the bolts in a cross-pattern to ensure even distribution of pressure. After mounting, always check the chain tension according to your motorcycle owner's manual specifications. For maintenance, clean the sprocket periodically to remove road grit or track dirt, and apply a high-quality motorcycle chain lubricant regularly to ensure the chain teeth interface remains smooth and efficient.
