It was inevitable that the GPz750R, introduced at the same time as the mould-breaking GPz900R, would be condemned to live in the shadow of its attention-grabbing bigger brother despite being, as Bike magazine put it, 'a Ninja in very way'. According to Britain's best-selling motorcycling journal, the GPz750R 'combines the 900's much acclaimed chassis with an engine that is reduced in size from 908 to 748cc but which delivers its power in an identical fashion – there's just less of it.' Less power there might have been but the GPz750R was still good for a top speed knocking on 130mph. Introduced alongside the GPz900R for the 1984 season, the GPz750R was produced for only three years before being replaced by the GPX750R in 1987.
