The Yamaha YZR500 is a Japanese racing motorcycle that was first introduced to the public in 1973. Mass production began at the same time and continued until 2002, so the model was produced for almost 30 years. The YZR500 was designed and manufactured to replace the 500 cc Honda YZ634A on race tracks. During production and over time, further versions appeared, mainly combining the use of a 500 cc inline engine. Examples of Yamaha YZR500 models were the following motorcycles: the OW48 of 1980 with an aluminum frame, the OW70 of 1983 with a different frame and a 17-inch front wheel, and the OW-98 of 1988 with a new shape of the exhaust pipes and exhaust system. Riders on the Yamaha YZR500 have won the World Championship 10 times, including Giacomo Agostini in 1975 and Wayne Rainey in 1990, 1991 and 1992. The bike has also triumphed in the constructors' championship several times.
