2024 Honda Grom SP: LOOK LIKE A ROCKSTAR.
Introducing the 2024 Honda Grom SP…
It’s hard to believe that Honda’s little Grom is already 10 years old. In the model’s first decade, it has already spawned a vibrant subculture of fun-seekers—from new riders attracted to its low seat height and unintimidating approachability, to experienced enthusiasts who like its modular styling and peppy performance. In both cases, the Grom often serves as a customization platform for those looking for an amusing project, which has helped to establish the Grom as one of the powersports industry’s most popular motorcycle 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.
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.
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.
ACCESSORY GRAPHICS KITS
A Grom is all about self expression and freedom of choice. And a great way to embrace both is with one of our Honda Accessories graphics kits. They make personalizing your Grom fun and easy!
LED HEADLIGHT
The Grom’s LED projector-style headlight not only looks great and is a major styling element, but it also provides excellent illumination.
FIVE-SPEED TRANSMISSION
The Grom features a five-speed transmission. You still get all the durability, control and efficiency of a conventional motorcycle, but the five gears help increase top speed for highway cruising.
LED TAILLIGHT
Forget about big, bulky taillights—the Grom’s LED lamp is bright and clear.
MULTI-FUNCTION DIGITAL INSTRUMENT DISPLAY
The instrument display features speedometer, odometer, tachometer, gear position indicator, A&B trip meters, fuel gauge, clock, and indicator for low/high beam.
OPTIONAL ABS
Our Honda Anti-Lock Braking System (ABS) is available on the Grom, which helps you make confident stops under less-than-ideal conditions.
HANDLING
12-INCH CAST WHEELS
Tough and strong, these cast wheels and wide tires are just what the urban rider needs.
INVERTED FORK SUSPENSION
Just like a top-of-the-line sportbike, the Grom features an inverted hydraulic fork front suspension for control and road feel.
SINGLE REAR SHOCK
Thanks to the Grom’s single hydraulic rear shock, you get a plush ride, even over choppy pavement.
2024 Honda Grom SP Totalmotorcycle.com Features and Benefits
DESIGN / STYLING
Currently in its third iteration, the Grom sports pared-down styling with straight lines, a small subframe and thick seat padding (seat height is a low 30 inches). Best of all, the four main body panels quickly attach/detach, facilitating customization—a hallmark of Grom culture that is welcomed by customers eager to personalize their rides. The Grom’s minimalist 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 disc, and a single-piston rear caliper with 190mm disc. Wheels are a 12-inch cast design—a signature feature of the Grom—with a five-spoke pattern.
Of special note, the available ABS system operates through an IMU (inertial measurement unit) that gives precise front-to-rear distribution of braking operation, depending on vehicle behavior.
