The sporty, pocketsize model that inspired a cultural revolution returns for 2020 with fun new colors, but it still has a serious side, with a SOHC four-stroke engine, fuel injection, four-speed transmission with manual clutch, LCD dash, stacked LED headlight layout and available ABS. It all adds up to excellent throttle response, remarkable fuel efficiency, nimble handling and a road-hugging but compliant ride, but the Grom’s most noteworthy feature is inarguably the diminutive size that promises approachability to new riders and fun to more experienced customers, contributing to its status as the industry’s best-selling sport bike.
