Honda Grom Stage 3 | DHM Piston, ECU Reflash, and Camshaft

Shocked!!

An absolute must have for any mini moto rider that was to squeeze more safe power out of the 125cc grom motor!! I can honestly say my grom is a whole different beast!! When they say is keeps pulling and pulling all the way to red line they are NOT joking !! Another great great bundle from DHM !!

The way it should be from factory

This is hands down a requirement for the Grom. I paired this with a new cylinder, ported head, light oil spinner and 5 speed, and it's like a new bike. No longer do I struggle going up hills. The bike absolutely rips and pulls hard to the redline.

Stage 3

Significant gain in power.. easy to install and most importantly absolutley stellar customer service! Best bang for the buck, would highly reccomend!
