If you’re looking to squeeze more power from your Grom Bore Kit, TBparts has the solution. This kit includes a bigger bore, camshaft, and rings. The cylinder is ceramic coated which cuts down on friction and makes the engine run cooler. Plus, it’s pump 91+ octane gas friendly. This is a quality kit that’s simple to install, just bolt it on and tune it.

Ten years ago, Honda all but started the modern minimoto craze with its diminutive Grom. It’s a cute little get-about that can do all kinds of fun things, from zipping to class in the city to pounding a backcountry trail or local race track. But it’s also one of the most approachable motorcycles on the market, thanks to a low seat height and no-thank-you helpings of horsepower that inspire youthful exuberance.

Grom Bore Kit: Boost Your Bike’s Power

The Grom’s success has inspired a lot of competition, including the Kawasaki Z125 Pro ($3,649-$3,849), which has a slightly larger bore and shorter stroke. Both bikes are designed to be nimble, reliable, and cheap to own and operate, and they’re backed by a wide dealer network.

Getting more performance out of your Grom requires less work from the engine, which can be accomplished by decreasing component weight. Adding a lighter seat, sprocket, or chain will increase both low-end torque and top-end speed. You can even make the Grom more nimble by going up or down in rear sprocket tooth count, which will increase or decrease your top-end power while adjusting your overall gearing.
