Tamiya 1/12 Yamaha YZR500 (0W70) Taira Version Kit TA-14075

To challenge the 1983 season, Yamaha brought out the YZR 500(OW70). Starting with a two-cycle, water-cooled, four-cylinder engine, the YZR500 was equipped with an abundance of innovative mechanics. Its four cylinders were divided into an upper and lower group consisting of two cylinders each. Crankshafts were attached to each group, giving a unique V-shaped layout.
