YAMAHAR5-A 350 1970 - 1972

　　The 1970 Yamaha R-5 was a pretty tought bike to top. R5-A is the best production street 350 cc in the world. By 1970, Yamaha had emerged as one of the leading Japanese motorcycle makers, behind Honda but ahead of Kawasaki and Suzuki. While Honda continued to embrace the 4-stroke ideal, Yamaha, like its other Rising Sun rivals, was still putting most of its faith in 2-stroke technology.
