The NS400R was Honda's road-going take on the NS500 V3 that Freddie Spencer rode to the 1983 500cc world title. Its compact liquid-cooled 387 cc V3 two-stroke sits low in a short-wheelbase alloy chassis, giving quick, precise steering and strong brakes. Power arrives smoothly for a two-stroke, building hard from around 5,000 rpm.
