1975 YZR500 (0W23)
Collection items
(1975 / Racing Machine)
This was a completely re-designed GP500 factory machine that replaced the 0W20 early the next year. Both the engine and chassis were lightened considerably and made more compact, and it was outfitted with a cassette type transmission that reduced set-up time and a stepped type tapered muffler. It debuted at the Belgian GP in 1974 and continued to be developed to become the machine that Giacomo Agostini rode to the Rider and Constructor championship titles a year later in 1975. Hideo Kanaya also rode this machine to win that year's Austrian GP, becoming the first Japanese rider ever to win a GP500 class race.
