For 2021 the Grom moved to a new long-stroke air-cooled 125 cc engine with a fifth gear, plus a bigger 6-litre tank and a new LCD dash with gear indicator. Fresh bodywork with simpler, easily removed panels made it even easier to personalise, while the compact chassis and 12-inch wheels carried over.
