Catch up with MotoBob's review of the MSX125 Grom


As expected, Honda’s cult, uber-cute MSX125 mini-bike is getting a significant update for 2021 – and this is the result! First launched in 2014, the 1970s monkey-bike-inspired, 12-inch wheeled 125 caused a global sensation for its mix of funky looks, easy-peasy rideability and huge fun factor – so much so the ‘Grom’, as it was called in Japan and the US, became something of a cult machine.
