17. Yamaha RD350
The RD350 is a 2-stroke motorcycle manufactured from 1973 to 1975 by the Yamaha Motor Company. It evolved directly from the piston port, front drum-braked, five-speed Yamaha 350 cc “R5”. It sported an air-cooled, parallel twin, 6-speed transmission, reed valve-equipped intake tract 2-stroke engine and was usually referred to as a sports bike. All models were equipped with automatic oil injection which they called “Autolube”, eliminating the need to mix gasoline and two-stroke oil. It then evolved into the more refined and cleaner running RD400C in 1976, then to the “D” and “E” variant in 1977 – 1978 and finally into the white RD400F in 1979.
