## Customer Reviews

### ⭐⭐⭐⭐⭐ Fits 2018 Grom
*by M***A on October 2, 2018*

Bought this (16T) hoping it would lower my rpms and increase top speed. It lowered my rpms but on flat ground it never reached above 55mph. Probably be better on hills versus flat surface. Everything is stock on my grom besides this sprocket.

### ⭐⭐⭐⭐⭐ Nice, inexpensive upgrade
*by B***H on August 30, 2016*

Looks well made. Fit and performed as described. My Grom accelerated a bit quicker and is more driveable around town. Nice, inexpensive upgrade.

### ⭐⭐⭐⭐⭐ Made riding higher speeds nice by bringing the rpms
*by A***R on June 27, 2017*

Fit perfectly. Made riding higher speeds nice by bringing the rpms down
