Vehicle Information
Yamaha FZR750R Motorcycle - Street (1987-1989)
The Yamaha FZR750R, produced from 1987 to 1989, is an iconic sport motorcycle, known for its liquid-cooled, inline four-cylinder engine and "Genesis" design with 5 valves per cylinder. Initially launched in 1987, the FZR750R Genesis produced approximately 106 hp at 10,500 rpm. In 1989, Yamaha introduced the FZR750R OW-01, a distinct and special homologation model. The OW-01 was not a simple update, but an entirely new platform, designed for racing. It featured a redesigned engine with different bore and stroke dimensions, titanium connecting rods, the EXUP system, a lighter aluminum Deltabox frame, premium suspension (Showa and Öhlins), and Nissin brakes. With approximately 120-121 hp, the OW-01 offered significantly higher performance. FAQ:
