The 2017 update gave the Grom/MSX125 a sharper, more aggressive look with an LED headlight, a stepped two-level seat and a low-slung exhaust. Underneath it kept the familiar air-cooled 125 cc fuel-injected single, four-speed gearbox, upside-down fork and 12-inch wheels, so it stayed the easy, playful mini-bike that made the name popular.
