Yamaha FS1E – The Must Have Bike For 1970’s British Kids

Launched in 1973 the Yamaha FS1-E was every young motorcyclist’s path to freedom. The ‘E’ suffix at the end of the models name simply represented which countries regulations the FS1 had been produced to meet. ‘E’ was for England. 

It was a 49cc moped that quickly got nicknamed Fizzie by the British youth and it was for many their first foray into life on two wheels. In total around 200,000 were eventually produced for the United Kingdom market earning it a solid place in both British motorcycle history and within the golden age of 2 stroke bikes.

In 1971 it was decreed that 16 year olds could only ride mopeds with less than 50cc and that had pedals. The idea being a moped with pedals would put an end to the carnage caused by allowing 16 year olds loose on their Japanese 250’s. 

Yamaha spotted a market and released their 60mph FS1E with a set of pedals on to conform to the UK laws.

You would be hard pressed to find a rider pedalling one of these mopeds. If they ran out of fuel, you’d more likely find them pushing it as it was easier than pedalling. 

Regardless, for 1973 the Yamaha FS1E was released and young riders couldn’t get enough of them.

At the heart of the bike was a 49cc, single cylinder, two-stroke, air-cooled engine with rotary disc valves and a four speed transmission as opposed to the five speed in the original FS1.

The gearbox was a little unusual with a 4-down gearbox and neutral at the top unlike the conventional 1-down, 4-up system. It took some getting used to but for new riders who knew no better it soon became second nature.

Revs need to be kept up in first gear but once you are off, the engine pulls nicely and everything is relatively smooth thanks to the disc valves.

Now by law the pedals were actually functional on the Yamaha FS1E. They can be rotated forward to rest as motorcycle footrests normally would and this is what they are best suited for. 

However, you could engage the pedal drive linked to the engine-drive by a short chain and actually pedal power the moped. 

It had low gearing and no freewheel so it made for hard work, but met the Government’s restrictions and so Yamaha made it as functional as possible. 

It was possible to start the engine with the pedals engaged, however when actually doing this it could cause issues with the cam and shaft arrangement which engaged the pedals and seizure of this system was common. 

Fuel needed to be mixed with two-stroke oil until the Autolube model was later released removing the need for manual mixing; until then though riders would need to carry around a bottle of oil to be mixed in when fueling up.

Drum brakes front and rear were the braking systems on the early models, later on the front they received a hydraulic disc brake. 

With such a lightweight chassis drum brakes were quite capable, although the later disc brake was a welcome addition.

The Japanese company played a great game with the Yamaha FS1E as once young riders were hooked on their fizzy, the idea was they would move up the Yamaha range to the RD250 once they hit 17 and weren’t as limited with licensing restrictions.

Honda and Suzuki both had competitive options but the four stroke SS50 from Honda wasn’t as well performing and Suzuki’s AP50 didn’t match up to the Fizzie.

Yamaha had captured the heart of the youth and gained cult status, with followers and enthusiasts to date. 

In 1977 the UK Government caught on to Yamaha and the law changed yet again. 16 year olds could now have a moped without pedals but all new 50cc motorcycles were restricted to 30mph.

By 1983 the Fizzie fizzled out. Sorry, it had to be done.

Yamaha FS1E Top speed

While the early Fizzy could push the needle near the 60mph mark when laid on the tank and with a decent wind behind you, the later FS1-E bikes were limited to 31mph. With a bit of tinkering though they could do 45mph once de-restricted. 

How much is a Yamaha FS1E Worth?

Today you can pick up a FS1 E for somewhere between £2,500-£5,000 in the UK.

The bikes are a worthy investment that will hold their value over the years, furthermore they will get harder to find in good condition. 

Already the Yamaha FS1 E is a nostalgic collectible and will remain so, I would think into the distant future. When a legacy is as strong as Fizzie’s that doesn’t disappear quickly. 

There is currently a very good condition 1977 Yamaha FS1-E DX model on eBay for £6,500 and it has had a ground up restoration so is a worthy collectors item.

A cool Fizzy sold with Bonhams for £6,900/$9,266. This was once owned by Richard Hammond (of BBC Top Gear fame). 


The Yamaha Fizzy was the ultimate toy for young new riders. It was so much more than a bicycle with a bolted on engine, it offered an opportunity for adventure and new found freedom. 

The Yamaha FS1E was a gateway to bigger and faster motorcycles and I am sure if you ask any rider that had one for their first bike, a smile will appear before any words are spoken.

That’s a special kind of motorcycle.

I wish I had known FS1-Es could manage 60+ mph when I had one in the 70s! This was the normal 'Daily telegraph' etc. line when complaining about 16 year olds 'racing' around on these mopeds and 'having accidents all over the place'. Stock examples could only manage about 45 mph. With a bit of tuning (porting, adjusting the inlet disk, skimmed cylinder head, changing the drive sprockets etc.) they could manage about 50 mph on a good day. I never knew anyone with a '60 mph' example - and a lot of my friends had them back in the day. Certainly, mine would not manage more than around 50 mph despite my having done extensive work to the engine. There were a few exotic Italian mopeds (e.g. Fantic) that could genuinely manage close to 60, but they were rare and very expensive compared to the FS1-E. Also, being a bit pedantic, the AP50 mentioned in the article was actually an A50P (A50 was the Suzuki 'motorcycle' version (i.e. no pedals) and the P suffix denoted the fitting of pedals for the UK market. Personally, I thought restricting mopeds to 30 mph (in 1977) was actually more dangerous. Too many drivers exceed the 30 mph limit and would, therefore, hassle the restricted mopeds to go faster and on roads with 40 or 50 mph limits, they became more vulnerable to faster traffic. In my experience, the 45 mph of the original FS1-Es allowed riders to interact with other road users more effectively. I have a Honda express moped (30 mph maximum) I still use occasionally for local trips and all too often the mirrors are full of a car 'tailgating' me trying to get me to speed up or move over!

Well. I was today years old when I learned the E stood for England. JFE 845N bought second hand £100 in April 77 but I wasn’t 16 until August so it was in the shed. Sat on,washed,polished,rode up the driveway. Went on an old airfield til we got thrown off but just had to wait till the day. By then I was at work and needed it for that but it was also my lifeline out of a village instead off bus routes.

I bought a Fizzy brand new on 1/1/74, PAH53M,I loved it, it was £170 brand new, I sold it 9 months later for £190, it was Candy Gold. I have bought and restored 2 since and sold them on, I would definitely buy and keep PAH53M if it ever tuned up . Also in the 70’s every petrol station I went to had 2 stroke oil on the petrol pumps,as there were so many 2 strokes around ,it was a few pence extra when you filled up for 35p.

I am from Cape town south Africa.The FS 1 was my first motorcycle when i was 16 years old and I loved it.The laws in South Africa did not require pedals,so there were no pedals on the model sold in this country.I had many many hours of fun on my FS 1 & I will always remember the independance that it afforded me...
