2025 Honda® Grom

GO GROM!

You know that old saying about good things coming in small packages—well when you’re talking about a Honda Grom it’s never been more true. Except, you better make that great things. Awesome things. Über-cool things. Because the Grom is such a blast to ride just about everywhere you need to go. And this year it’s better than ever, because we have three trims to choose from: the standard Grom, the Grom ABS with front-wheel anti-lock brakes, and the Grom SP, with a unique graphics treatment. And every Grom features plug-and-play body panels that are easy to remove if you want to add some custom graphics of your own—it’s like a blank canvas that you can ride. So get out and enjoy the ride—once you go Grom, there’s no going back.

Features may include:

PERFORMANCE

124cc FUEL-INJECTED ENGINE

Nobody can match our reputation for engines, and even though the Grom may be compact, it’s a giant in terms of performance and reliability.

COMFORT

LOW SEAT HEIGHT

At just 30 inches the Grom makes it easy to flat-foot it in parking lots or at stop lights. Plus, the seat features thick padding so it’s comfortable, especially for taller riders.

ENGINEERING

HYDRAULIC DISC BRAKES

The Grom features 220mm front and 190mm rear single disc brakes for excellent stopping power.

STYLE

UNIQUE BODYWORK

Part of the fun of owning and riding a Grom is the way it looks. Plus, its unique bodywork is easy to remove if you want to customize it even further. In addition, the engine, exhaust, wheels and swingarm are all blacked out for an edgy look.
