In 1967, Yamaha introduced the YR-1 as their first ever 350cc street model. The YR-1 Grand Prix was Yamaha's biggest bike to date . Ultra high performance 2 stroke with auto lube oil injection system that mixes the gas and oil automatically! 36 bhp at 7500 rpm! Awesome classic that has kickstart only, effortless and reliable starting every time. Cruises at 80 mph and top speed 100-110 with a quarter mile time 14.0. With a 14 second ET these defeated many a larger capacity bike, they are considered rare today. Although it vibrates a bit, its Fun to ride and has power to spare especially being a two stroke on a street bike, this thing gets up and goes! Basically their Grand Prix racing motorcycle in street legal trim Reviewed in the March 1967 Cycle World magazine.
