Here's the ratios from the Monkey service manual. The Grom/Super Cub and the new CT-125 use the same internal ratios and the primary ratio is almost the same between the manual and auto clutch versions. Only the final drive ratio varies between the small wheeled bikes and the Super Cub. The CT will have three more teeth on the rear for off-road use.

The biggest reason for the taller gearing on the Monkey (lower numerically) is it's 12" wheels.

1st 2.500
2nd 1.550
3rd 1.150
4th .923

Pri. 3.350
Fin. 2.266
