The Yamaha YZF-R7 or OW-02 is a race homologation motorcycle of limited production run of only 500 units. It was designed to compete in the Superbike World Championship and Suzuka 8 Hours endurance races.
It has a 749 cc (45.7 cu in), DOHC 20-valve (5 valves per cylinder) inline-four engine producing 106 hp (79.0 kW), or 139 hp (103.7 kW) when the other, unused bank of fuel injectors is activated, and over 162 hp (120.8 kW) in race trim.
The R7 was built for racing 'out of the box', implied by the chassis, which was derived from information and geometry from the YZR500 machines of the period. The R7 was specified with Öhlins suspension components, a shortened Deltabox II frame and weight of just slightly over the 162 kg (357 lb) minimum of superbike regulations.
The intentions of the R7 were further underlined, with its designation of "OW-02" and the lack of any pillion/passenger provision.
