2018 Honda Grom

Grom Love. We Call It Gromance.

Want to have some serious fun getting from one place to another? As thousands of converts already know, that’s where the Honda Grom comes in.

Compact, low to the ground, pocket-sized in terms of price and parking, but such a blast it’ll put a giant smile on your face whenever you turn the key. Last year we gave it some sweet updates—a new headlight, new two-step seat, new bodywork, and a new muffler. This year you still get all that plus available ABS, along with a healthy dose of Gromitude.

Want to know more? The Grom features a 125cc engine, with a fun factor that’s off the charts. Its unintimidating size makes it great for beginners, and a total, flickable joy ride for riders with more experience.

So what are you waiting for? Get yourself a Honda Grom, and start the Gromance. You can do it, and we’re here to help.


  • MULTI-FUNCTION DIGITAL INSTRUMENTS: Instrument display features speedometer, odometer, tachometer, A&B trip meters, fuel gauge, clock, and indicator for low/high beam.
  • LED HEADLIGHT: The Grom’s LED projector-style headlight not only looks great and is a major styling element, but it also provides superior illumination.
  • 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.
  • NEW OPTIONAL ABS: For 2018, Honda’s Anti-Lock Braking System (ABS) is available on the Grom, which helps you make confident stops under less-than-ideal conditions.
  • 12-INCH 10-SPOKE WHEELS: Tough and strong, these cast wheels and wide tires are just what the urban rider needs.
  • 125 CC FUEL-INJECTED ENGINE: Nobody can match Honda’s reputation for engines, and even though the Grom may be compact, it’s a giant in terms of performance and reliability.
  • FOUR-SPEED TRANSMISSION: The Grom’s four-speed transmission gives you all the durability, control and efficiency of a conventional motorcycle.
  • HYDRAULIC DISC BRAKES: The Grom features 220 mm front and 190 mm rear single disc brakes for excellent stopping power.
  • SINGLE REAR SHOCK: Thanks to the Grom’s single hydraulic rear shock, you get a plush ride, even over choppy pavement.
  • LOOK THE PART: Sharp bodywork, a LED headlight and cowl, and a low-mount muffler keep the 2018 Grom looking cooler than ever.
  • FUEL CAPACITY: Who says being on a budget can’t be fun? With its 1.45-gallon fuel tank you can venture far and economically too.
  • LOW SEAT HEIGHT: At just 30 inches the Grom makes it easy to flat-foot it in parking lots or at stop lights.
  • TWO-UP CAPABILITY: Want to share the fun with a friend? No problem—the Grom makes it easy to bring a passenger along.
  • LED TAILLIGHT: Forget about big, bulky taillights—the Grom’s LED lamp is bright and clear.
