■ Note
If you use other than the stock sprocket (15T), there will be a discrepancy between the displays of the speedometer.
In order to fix this problem, it is necessary to purchase our speed sensor kit for stock speedometer.
For replacing the mission, it would be required the flywheel puller tool, lock nut wrench, rotor holder, etc. for GROM/MSX125.
Flywheel puller (for GROM/MSX125/Monkey125) 00-01-1671
Rotor holder 00-01-1001
Lock nut wrench 00-01-1681
