The FS1-E was the UK model. Machines registered in the UK from 1 August 1977 were restricted to a maximum of 31 mph. Originally the FS1-E was built as a five-speed transmission light motorcycle. It was originally called the FS1. Due to the regulations in Europe, the FS1-E was downtuned with a four-speed transmission. The Yamaha FS1-E has a 49 cc single cylinder two-stroke air-cooled rotary disc-valved engine with a four-speed gearbox. The FS1-E was the FS1 with the suffix E, which stood for England (differing from the models sold in other countries as the FS1-E had more cycle parts in common with other UK-imported Yamaha models).
Yamaha introduced various improvements such as a front disc brake (FS1-E DX model) over the years, and later an autolube model with a two-stroke oil tank and oil pump, with no need to manually mix two-stroke oil into the fuel tank.
This FS1E has resided in a private collection on display for 20 years, and is ready now to to be recommissioned and enjoyed once more on the road. The “Fizzy”is offered with a UK V5 document, and is said to be in good order in all respects.
