HRC prepared this race-only version of the MSX125 Grom for a one-make HRC Grom Cup series run around Japan in 2021. Road equipment was stripped off and replaced with a race ECU and wiring loom, racing cowl, tail and belly pan, engine and grip guards, a high-level exhaust and treaded Dunlop tyres, all in HRC colours. It cannot be registered for road use.
