The NS250 (sold in Japan as the NS250F) was the unfaired sister of the NS250R, sharing its liquid-cooled 90-degree V-twin two-stroke. It went without the full fairing and used simpler cycle parts, giving a cheaper, more upright entry into Honda's quarter-litre two-stroke line. It arrived in 1984 alongside the faired R.
