4-speed Close Ratio Transmission Gear Set for GROM/MSX125

This "4-speed close-ratio gear set" allows you to achieve close ratios at a low cost by utilizing parts from the normal 4-speed transmission.
Developed for big bore kits, it primarily reduces the drop in RPMs from 3rd to 4th gear.
When installed simultaneously with a Takegawa big bore kit, it allows you to utilize the engine's power band smoothly and effectively.
It can also be used with a normal engine.
If you install the 4-speed close-ratio gear and use the normal sprocket size (15 teeth), a speed sensor kit is not required.
If you use a sprocket size other than the normal 15 teeth, there will be an error in the speedometer reading.
To correct this, a separate purchase of Takegawa's speed sensor kit for normal speedometers is required.
When replacing the transmission, tools such as a flywheel puller, locknut wrench, and rotor holder compatible with the GROM/MSX125 will be necessary.
Compatible models:
: GROM (JC61-1000001)
: MSX125 (MLHJC618_D5000001)
