Honda Brings Grom With More Range & New Powerplant To U.S.

All-new 2022 Grom is now easier to customize and peppier.

Published on 03.04.2021

When Honda introduced its 125cc Grom for the 2014 model year the miniMOTO concept was firmly put on the map, spawning an army of enthusiasts that embraced the mini-bike with remarkable passion. To this day, the Grom holds a cult following of fun-seekers who use the versatile pint-sized bike for everything from pit errands to round-the-world travel.

Already launched in some markets last fall, the latest iteration of the Grom is now coming to the U.S. market for model-year 2022, featuring new quick-release bodywork that facilitates customization, more fuel capacity, an updated LCD display and a peppier new engine, now with a fifth gear. 


Now in its third iteration, the Grom sports all-new, pared-down styling with straighter lines, a smaller subframe and thicker seat padding (seat height is still a low 30 inches). In addition, the four main body panels quickly attach/detach, facilitating customization—a hallmark of Grom culture that is sure to be welcomed by customers eager to personalize their rides.


The 2022 Grom’s minimalist aesthetic is complemented by its blacked-out engine, exhaust, wheels and swingarm, while a special SP version has a gold finish on the fork, wheels and brake calipers, plus a yellow shock spring.

Practical improvements include an increase in fuel capacity, from 1.45 gallons to 1.59 gallons. In addition, the upgraded LCD digital dash now has a gear-position indicator, alongside the speedometer, tachometer, twin trip meters, fuel gauge and clock.


The Grom’s updates are more than skin deep. The new engine now includes—for the first time—a fifth gear for more comfortable cruising. Honda’s engineers achieved this by specifying a wider spread of gear ratios and replacing the previous 34-tooth final-drive sprocket with a 38-tooth size. The changes not only provide peppier acceleration from low speeds, but increase top speed as well.

The 125cc two-valve, overhead-cam, air-cooled engine has a compression ratio of 10:1 (versus 9.3:1 with the previous model). This is achieved via an undersquare design, with a narrower bore and longer stroke than its predecessor—50.0 mm and 63.1 mm, compared to 52.4 mm and 57.9 mm with the previous engine.

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, and a welcome addition to the 2021 model is a replaceable oil filter, a practical upgrade from cleaning the previous model’s oil spinner and screen.

Do-it-yourselfers will also appreciate the redesigned exhaust downpipe and muffler, which are now two separate parts for ease of replacement.


The suspension remains unchanged with a 31 mm inverted fork and a single shock. The brakes feature a dual-piston front caliper with 220 mm disc, and a single-piston rear caliper with 190 mm disc. Wheels are a 12-inch cast design—a signature feature of the Grom—but the 2021 model boasts a new five-spoke pattern.

Of special note, the available revamped ABS system operates through an IMU (inertial measurement unit) that gives precise front-to-rear distribution of braking operation, depending on vehicle behavior.

Colors and Pricing

The 2022 Grom is offered in Queen Bee Yellow, Matte Black Metallic and a special SP color option that has stylish graphics and a yellow shock spring, plus a gold finish for the wheels, brake calipers and fork. The ABS version is available in Candy Blue.

  • Grom: $3,399
  • Grom SP: $3,499
  • Grom ABS: $3,599

I sure hope the 2022 Honda Trail 125 ABS has these upgrades! I would happily pay $200 extra for it!
