2025 Honda Grom Features & Benefits

Small in stature, but huge in popularity and fun, the Honda Grom is back with a fresh new look for the 2025 model year. Marking the fourth generation of the immensely popular pint-sized model, this update brings redesigned bodywork for an aggressive new look. Popular in part for its customization potential, the Grom can be customized via a full range of new Honda Accessories, including both storage and style upgrades. Appealing to riders of all backgrounds, thanks to its approachable, peppy and smile-inducing character, the Grom continues to be one of the powersports industry's top-selling models—and the undisputed emperor of the miniMOTO world.

HISTORY

Since its 2014 model-year introduction, the Grom has always been about enjoyment, serving as an inspiration and focal point for riding clubs and social-media groups, while also supporting a healthy aftermarket of accessory and performance parts. Eliciting laughs from those who ride it, thumbs-ups from fellow motorists and traffic-light smiles from pedestrians, the Grom is also a motorcycling evangelist, spreading positive powersports vibes wherever it goes. For the 2017 model year, the model underwent a comprehensive redesign for a sharper, more aggressive look.

The Grom's current iteration (introduced for the 2022 model year) features striking bodywork that facilitates customization, plus a peppy engine with a fifth gear. As always, the model boasts amazing gas mileage, low operating and maintenance costs, attention to detail and Honda's legendary reliability.

For the 2025 model year, the Grom receives refreshed styling with all new bodywork and an available host of new, innovative accessories that elevate the miniMOTO experience.

Importantly, the Grom's success has also served as the springboard for a trio of retro-themed miniMOTO siblings: the Monkey and Super Cub in model-year 2019 and the Trail125 for model-year 2021.

DESIGN / STYLING

The fourth-generation Grom is outfitted with almost entirely new bodywork, giving the miniMOTO icon a fresh look. From the headlight cover to the shrouds, tank cover and side covers, each component has been carefully redesigned, offering aggressive style, while prioritizing rider comfort. The four main body panels quickly attach and detach, facilitating customization—a hallmark of Grom culture that is welcomed by customers eager to personalize their rides. The Grom's sleek aesthetic is enhanced by its blacked-out engine, exhaust, wheels and swingarm.

Practical features include an ample fuel capacity of 1.59 gallons, and the LCD digital dash has a gear-position indicator, alongside the speedometer, tachometer, twin trip meters, fuel gauge and clock.

ENGINE / DRIVETRAIN

The Grom's appeal is more than skin deep. The engine is a modern design that includes a fifth gear for comfortable cruising. The gear ratios provide not only peppy acceleration from low speeds, but good top speed as well.

The 125cc two-valve, overhead-cam, air-cooled engine has a compression ratio of 10:1. This is achieved via an undersquare design, with a narrow bore and long stroke—specifically 50.0mm and 63.1mm, respectively.

State-of-the-art PGM-FI fuel injection assures optimal fuel delivery and highly efficient combustion. A large, 2.5-liter airbox houses a panel-type, wet-paper filter with a 10,000-mile life in normal riding conditions. Many Grom owners prefer to do their own maintenance, so the replaceable oil filter is a welcome feature.

Do-it-yourselfers also appreciate the exhaust downpipe and muffler, which are two separate parts to simplify replacement.

CHASSIS / SUSPENSION

The suspension comprises a 31mm inverted fork and a single shock. The brakes feature a dual-piston front caliper with 220mm rotor, and a single-piston rear caliper with 190mm rotor. Wheels are a 12-inch cast design—a signature feature of the Grom—with a five-spoke pattern.

Of special note, the available front ABS system operates through an IMU (inertial measurement unit) to reduce the possibility of front-wheel lockup and to keep the rear wheel down during aggressive braking.

ACCESSORIES

For 2025, a range of new accessories are available for the Grom. The Knuckle Visors, Meter Visor and Under Cowl offer both style and function while the Cloth Seat Bag, Rear Carrier and Cloth Saddlebags bring a new level of utility. The Grom SP is outfitted with the Under Cowl as standard equipment.

Transferable one-year limited warranty; extended coverage available with a HondaCare Protection Plan
