2014 - 20 Honda Grom Light Weight Rear Sprockets

EVERY OUNCE COUNTS. EVERY POUND MATTERS.

When you're building a Honda Grom for performance, weight matters—and on a Mini Moto, even small reductions can make a difference.

The MotoBros Lightweight Honda Grom Sprocket is precision-made from 6061 aluminum, giving you an excellent combination of light weight, strength, and durability for your performance Grom build.

Why does that matter?

Because a sprocket isn't just weight sitting on the motorcycle—it's part of the rotating mass of the rear wheel assembly. Reducing weight here helps create a lighter, more responsive setup.

On a 400+ pound motorcycle, saving a pound might not sound like much.

On a Mini Moto, EVERY POUND COUNTS.

The Grom doesn't have massive horsepower to overcome unnecessary weight, which is exactly why we focus on making the entire motorcycle work better. Lightweight sprockets, wheels, exhaust components, and other performance parts all add up.

BUILT FOR PERFORMANCE 6061 Aluminum Construction Significantly Lighter Than Traditional Steel Sprockets Reduces Rotating & Unsprung Mass Strong, Lightweight Performance Design Sharper, More Responsive Feel Perfect for Street, Track & Mini Moto Racing Designed for the Honda Grom

We don't believe building a fast Grom is only about adding horsepower.

It's about making the horsepower you already have work harder.

LOSE THE WEIGHT. SHARPEN THE BIKE. BUILD IT BETTER.

LIGHTER. FASTER. STRONGER.
