Ups

• Save the planet. Ride a Grom. Honda claims it achieves 166.5 mpg.
• Light weight, low seat height, and less than 10 hp make it Neverland’s moto of choice.
• At $3,599, you can afford it from cash earned on your summer paper route.

Downs

• The lighthearted Grom may pressure you into acting like a kid.
• It’s not the only minimoto on the block anymore.

Verdict

The little Grom is a big deal. It sells in huge numbers, it’s cheap, and gets, like, three times better gas mileage than a Toyota Prius. Plus, it’s so fun to ride that it appeals to every demographic.

Overview

Ten years ago, Honda all but started the modern minimoto phenomenon with the introduction of the Grom, a cutesy get-about with 12-inch wheels, a sub-10 hp single-cylinder engine, and ergos designed to fit an adult. You’d think that would be a recipe for a niche product if ever there was one…but no. Between its introduction in 2014 and its most recent update in 2022, Honda sold more than 750,000 of them worldwide.

If one were to identify the most significant trends in motorcycling of the last decade, the proliferation of minimotos would definitely make the list. By tapping into the unserious side of motorcycling, the Grom resonates with a broad demographic. It’s as easy to imagine a college student rushing to class on one as it is a bunch of retired boomers spending their wintry weekends racing them in a homegrown ice racing championship.

The Grom is as approachable as any motorcycle currently on the market. But in the case of the Grom, “approachable” is a euphemism for rowdy. Seriously, it’s so, ahem, “approachable” it may turn you into a subversive hooligan. That’s because light weight, a low seat height, and a no-thank-you helping of horsepower inspire youthful exuberance.

If altruism is more your bag, Honda claims the Grom achieves 166.5 mpg. So, yeah. Save the planet. Ride a Grom. And then do burnouts in front of Al Gore’s earthship.

Updates for 2024

The third-generation Grom, introduced in 2022, is unchanged for 2024.

Pricing and Variants

The Grom is available in three versions. The base model ($3,599) is available in three colors: Blue Raspberry, Pearl White, and Nitric Orange. For $100 more, the Grom SP includes a special graphics package. The Grom ABS ($3,799) includes ABS, but is only available in Pearl White.

Honda also offers a series of accessory graphics kits, including a Grom-ish riff on HRC livery.

Competition

The Grom’s success has inspired lots of competition, chief among them the Kawasaki Z125 Pro ($3,649–$3,849). There’s not a lot between them, but the Honda does have a lower seat height (30.0 inches compared to 31.7 inches), and a five-speed transmission (the Kawasaki has a four-speed box). Compared to the Honda, the Kawasaki’s 125cc engine is oversquare (larger bore, shorter stroke), but performance figures are very close between both bikes. The Z125 Pro is currently not available with ABS.

CFMoto brings two 126cc minimotos to the party. The Papio CL ($3,299) is a scrambler version complete with 12-inch knobby-ish tires, while the Papio SS ($3,299) is a retro-sport version that has some serious 1985 GSX-R750 vibes. Both bikes have six-speed transmissions, but at 251 pounds (claimed), they’re roughly 27 pounds heavier than the Grom, though part of that is down to the 0.3 gallon of extra fuel sloshing around in the larger fuel tank. ABS comes standard.

The Benelli TNT 135 ($3,199–$3,269) is the brute of the minimoto world with a 134.7cc engine, producing a claimed 11.3 hp and 7.4 lb.-ft. of torque. While the quoted torque figure is about the same as the competition, the horsepower number is 1.3 more than the Honda’s. There’s no replacement for displacement, even in the minimoto realm. Including a full 1.9-gallon fuel tank, the Benelli weighs a claimed 255 pounds. Benelli, an iconic Italian marque, though now owned by China’s SSR Motorsports, gives the TNT 135 its own style with a trellis frame and upswept exhaust.

The Grom faces serious competition from within its own ranks. Honda has expanded its minimoto lineup to include the Z50A-styled Monkey ($4,299); the Super Cub C125 ($3,899), the latest version of the highest-selling motor vehicle of all time; and the nostalgic Trail125 ($4,099), all of which are powered by the Grom’s 124cc SOHC engine. The Monkey, however, is the only one that shares the Grom’s shrink-wrapped style and 12-inch wheels (after all, it’s basically a restyled Grom). The other models are mini in displacement and weight, but compete less directly with the Grom.

And then there’s Honda’s Navi, which undercuts the whole lot of them. Under being the operative word here. If the Grom is minimoto, the Navi is micro-moto. At $1,807, it’s by far the least expensive motorcycle here. At a claimed 234 pounds it’s (just barely) the lightest. And its 109cc engine is the smallest-displacement engine in the club. The Navi’s no-shift automatic CVT transmission ups the accessibility factor, but may make it less appealing to the enthusiast crowd. With a plastic cubby where a larger engine would typically reside, the Navi is oddly practical despite its size.

With loads of competition, the Grom is almost a victim of its own success. Except as the progenitor of the modern minimoto phenomenon, the Grom name arguably carries the most cachet. Plus, loads of aftermarket options and easily removable bodywork make it a go-to for customization.

Powertrain: Engine, Transmission, and Performance

The Grom uses a SOHC 124cc four-stroke single that produces a claimed 9.7 hp at 7,000 rpm and 7.7 lb.-ft. at 5,500 rpm.

Beginning with the 2022 version, Honda updated the engine to make it more fuel efficient and easier to maintain for novice wrench spinners. A slightly longer stroke and smaller bore, as well as a compression ratio bump from 9.3:1 to 10.0:1, increases the engine’s torquey feel and responsiveness. The addition of a fifth gear and revised final drive gearing helped boost roll-on performance while making top-speed cruising more comfortable. Win, win. In real-world testing, the new fifth gear feels almost like an overdrive. Maintaining momentum up steep hills will require downshifting to fourth—or even third—gear.

On level ground, with an average-sized rider on board, the Grom will hit around 60 mph. While 9.7 hp isn’t a lot, as we noted in our first ride review of the original Grom, it’s “plenty to get the holeshot on unsuspecting Camrys.”

Chassis and Handling

The Honda Grom uses a nonadjustable 31mm inverted fork with 3.9 inches of travel and a single preload-adjustable shock with 4.1 inches of travel.

At around-town speeds, the suspension is perfectly adequate. But as the engine reaches its speed limit, so does suspension performance. But you really can’t complain, considering the Grom costs less than $4,000. For the average use case, the setup works just fine. If you’re the kind of person who’s taking your Grom to a local kart track, you’re probably planning on replacing suspension components anyway.

Brakes

The Grom has a dual-piston caliper and a 220mm disc in the front, and a single-piston caliper and 190mm disc in the rear.

Given the bike’s light weight, its dual-piston caliper grips the front rotor with plenty of strength that gives a solid feel at the lever. ABS models feature an Inertial Measurement Unit (IMU).

Fuel Economy and Real-World MPG

Honda claims the Grom achieves 166.5 mpg. Our tester averaged 103 mpg, but he was admittedly heavy-handed with the throttle and weighs nigh on 200 pounds.

Ergonomics: Comfort and Utility

With a 30-inch seat height, the Grom is one of the most approachable motorcycles on the market. The 2022 update included a more comfortable seat. Despite its small stature, the ergonomics aren’t shrunken so even tall riders can get comfy.

The Grom is one of the most economical bikes to own. It’s inexpensive to buy new, cheap to run, cheap to maintain, and cheap to insure. We’re not saying that a 124cc single-cylinder engine is the answer to the world’s energy crisis, but if we replaced all of Silicon Valley’s Teslas with Groms, the world would be, if nothing else, more fun.

Electronics

With fuel-injection, an LCD dash, and available ABS, the Grom has all it needs.

H2: Warranty and Maintenance Coverage

The Grom has a one-year unlimited-mileage warranty with extended coverage available through HondaCare Protection Plan.

Quality

From lawn mowers and generators to decades of XRs and CRFs, Honda’s little air-cooled singles are practically a backbone of modern civilization. That might be a stretch, but seriously, Honda is renowned for building bulletproof small-capacity engines. The Grom is reliable and backed by a robust dealer network. Fit and finish isn’t flashy, but it’s tidy and built to last.
