The 2021 CB125F was a ground-up redesign around a new long-stroke eSP engine and a lighter tubular steel frame, cutting about 11 kg from the previous bike. It gained an LED headlight, digital dash and sharper CB-family styling, and a smaller 11-litre tank that still gives a claimed range of around 800 km thanks to roughly 65 km per litre.
