Ow60 - 001 yamaha's first foray into the 500cc gp class came in 1973 with the inline four, piston-port 0w19. The company stuck with this basic design up until 1980 (although the final model, the ow48r, had the outside cylinders reversed) when they decided that to stay competitive, a new, rotary-valve engine design, would be required.
Realizing that the era of the in-line 4-cylinder engine was over, yamaha was thirsty for a radical change and new possibilities. One of them was the yzr500 (0w60) - an advanced version of the 0w54, powered by a rotary disc valve-inducted square-four engine.

0w48r: at round 4 of the season, the yzr500 returned to a steel frame, and the engine had the outer cylinders reversed and thus rear-directional exhaust. 1981: 0w53: same rear-directional exhaust as the 0w48r, and the aluminum frame used a squared cross-section.
The square four design went on to dominate 500gp racing, taking two more world titles (1981 with marco lucchinelli and 1982 with franco uncini) and winning a total of 50 races alongside the seven consecutive constructor’s championships.
Despite the change of engine configuration, yamaha’s rotary-valve, square-four 0w54 still lost out to suzuki’s revised and lighter 1981 rg500, so the factory went all-out for season 1982. It was determined to make amends for roberts’ disappointing third place in the points table behind suzuki riders randy mamola and season champion marco.
