My favorite sprocket ratio thus far!

Running a stage 2 2025 Grom with 14T front and 37T rear sprocket. Very happy with the results. Able to hold speed from 4th to 5th gear (60MPH) and slowly climb up in speed after. Only installed it last weekend and haven’t driven too much but so far so very good!

Nice and quiet

Lightweight and holes fit my 24 grom. Red looks sweet with a gold chain
