Honda Grom History and Overview

First introduced to the U.S. in 2014, the Honda Grom, also called MX125 in Europe and East Asia, has become one of the most popular MiniMoto bikes due to its easy handling, low cost, and reliability. The Grom combines standard motorcycle functionality with Honda’s engine reliability for a friendly but peppy riding experience. Some have confused the Grom as a scooter, but that would be selling this bike short. Unlike most scooters that have a continuous variable transmission (CVT) and use “twist and go” throttle, the Grom has five shiftable gears.

The 2022 model received a design facelift by allowing the body panels to be removed, and the transmission was upgraded from four speeds to five. The instrumental panel is very clear and compact, displaying multiple data points into a small space. In typical Honda fashion, the build quality is high, and they use top-notch materials. Detractors of the Grom will cite its small size, height, and short wheelbase, which may stunt good riding habits once you upgrade to a larger bike. The consensus from reviews is that the Grom is best suited for beginner riders or a novelty bike for experienced riders.

  • Is the Honda Grom a scooter?

    No. Although it looks like a scooter with its smaller size, it technically isn’t a scooter since the power to the rear wheel is driven by a five-speed transmission. Most scooters use a continuous variable transmission (CVT) and use “twist and go” throttle, but Grom has five shiftable gears, so it has more in common with a motorcycle than a scooter. The powers at be over at Honda have called the Grom a “miniMoto.”

    Aesthetically the Monkey has a vintage, laid-back, retro design compared to the Grom’s aggressive and sporty look. With a base MSRP of $3,999, the Monkey is more expensive than the Grom. Although the Monkey is suitable for 2 riders, it doesn’t have foot pegs, unlike the Grom, which does, and the Monkey has a dual shock suspension set up, whereas the Grom utilizes a single shock suspension. Owners have claimed the Monkey’s soft seat, with its 1970’s banana seat vibe, is much more comfortable. The riding position on a Monkey is slightly more upright compared to the Grom.
