The ESJOT 46-tooth rear sprocket is designed for owners of QJMOTOR SRT 700 X and Benelli TRK 702 motorcycles who require a high-durability, precision-engineered replacement part for their drivetrain. This sprocket offers exceptional reliability through strict adherence to OEM manufacturing standards, though users must ensure their current chain pitch is compatible with the 520 specification before installation.

No, the package includes the sprocket only. It is recommended to use your existing high-quality hardware or replace with new OEM-specified bolts.
No, this sprocket is designed exclusively for a 520 pitch chain. Attempting to use it with a different pitch will lead to premature wear and potential mechanical failure.
Generally, sprockets should be inspected at every oil change and replaced when the teeth show significant signs of 'hooking' or wear.
If you have basic mechanical knowledge and the necessary tools like a torque wrench and motorcycle stand, it is a straightforward installation. If you are uncertain, consult a certified technician.
The internal diameter is 125 mm.
Verify that the rear wheel alignment is correct and that the chain tension is adjusted to factory specifications.
Ensure that the internal diameter matches your carrier hub and that all mounting bolts are tightened to the correct torque pattern.
Before installing this sprocket, ensure your motorcycle is securely placed on a paddock stand or center stand. Verify that your chain and front sprocket are in good condition; it is highly recommended to replace the entire drivetrain (chain, front, and rear sprocket) as a set. For installation, clean the sprocket carrier area thoroughly to remove old grease and road grit. Apply a light coating of anti-seize to the mounting bolts and torque them to the manufacturer's recommended settings. Regular maintenance involves cleaning the chain with an approved lubricant and checking sprocket teeth for signs of uneven wear every 500 to 1,000 miles.
