History and Parts: Yamaha R5 - Yamaha R5B - Yamaha R5C

Prior to 1970’s motorcycles were fairly expensive. Each model was innovative and parts were specific to each and every models. However as popularity of racing bikes and demand for their street versions grew, manufacturers were looking for ways to produce in bulk and save cost. Yamaha therefore started factory produced racers - modular motorcycles with interchangeable parts. The great example are the motorcycle classics - Yamaha DS7 R5


Yamaha R5 History & Specs

The Yamaha R5 was introduced to the market in 1970 - developed as a successor to the 1965 305cc YM1, 1967 350cc YR1, 1968 YR2 & 1969 YR3 / R3 models. It was a street bike designed around the race track success of Yamaha two stokes.


The R5 350 Yamaha motorcycle was a slightly larger sister of the DS7 250cc twin. It was lighter and slimmer than earlier Yamaha motorcycles and it had excellent handling and engine performance. The fact that it was modular meant, that Yamaha R5 350 parts were interchangeable with other models and thus cheaper to replace.


Yamaha R5 350 had air cooled 350cc twin two stroke engine with piston port controlled fuel injection. The horizontally split crankcase housed 5-speed gears and the front wheel as well as rear wheel were fitted with expandable drum brakes. It came in a range of bright colours as well.
