Peugeot Speed Versions
December 27, 2020
US-model Peugeot mopeds were made in three different speed and power versions to comply with different state laws. For example, mopeds in California go 30mph, but in Nevada or Arizona they go 25mph. Each state has different moped laws. Peugeot moped speed versions are referred to by the speed version codes U1, U2 and U3. The speed version code appears after the model on the I.D. plate, on the frame behind the headlight. For example, a 103 LVS U2 is a 25mph moped with 1.5 horsepower.
U1 is 20 mph and 1.0 hp, U2 is 25 mph and 1.5 hp, U3 is 30 mph and 2.0 hp

Cylinder: 102 U2 and U3 are the same, but 103 U1,U2 have a different cylinder than 103 U3, with a slightly smaller exhaust port. A U1,U2 cylinder can be converted to U3 by mild “porting”, by grinding the top pf the port, at the cylinder wall, higher by 1.0 mm, and each side wider by 0.5mm.
Head: The 103 U1,U2 low compression head can be converted to U3 by milling off 1 or maybe 2 mm. Leaving off the head gasket instead, is a quick and beneficial way to increase the compression ratio. But when the head is moved closer to the piston, contact can happen. Care must be taken. A squish clearance of 0.6mm (0.024″) is recommended when cold. A minimum combustion chamber volume of 5.0cc is recommended for a 50cc swept volume, to have a maximum compression ratio of (50+5)/5 equals 11 to 1.
Reed Valve: The 103 U1 and U2 small round reed plate holes can be widened to “normal” round holes. Furthermore a Tomos A35 reed valve fits, and gives even more power increase because the reed plate holes are rectangles with more area. Expect a stock healthy 103 LVS U3 to go 4-5 mph faster and accelerate quicker, with just a Tomos reed valve, with no side effects.
Carburetor: To upgrade an 8.5 to a 12mm carburetor you can replace the bare body. It is too difficult to carve out because the non-removable brass spray tube is in the way.
Intake Pipe: To upgrade an 8.5 to a 12mm intake manifold you can carve out the inside, or replace it. On a Peugeot 102 the only difference between a U2 and U3 is the intake manifold.
Exhaust: The 103 U1 muffler is gloss black and has a U-turn in the removable baffle, and a hemispherical end cap. The 103 U2 and U3 muffler is dull black, with a straight tube removable baffle and a vertical channel end cap. The wider end of the vertical channel should face down, or the bike will go slower.
Baffle tube: Early 103 U3 models came with a short baffle tube. These went 35mph and were the fastest moped. Then in 1978 Peugeot had to slow all the bikes down to meet 30mph DOT requirements. They issued a recall to all 103 U3 owners to bring their mopeds into their dealer to have the long baffle put in. All later 103 U3 models were made with long baffles. Simply removing the baffle makes it only a little bit louder, but adds 2-3 mph in speed.
Belt Pulleys: The front pulley is the same on all 102 and 103-no-variator models. The variable front pulley on 103-variator models is the same except for the centrifugal variator weights are different on U2 and U3 models. All 102’s have the same 7 inch rear pulley. All 103’s have the same 8″ rear pulley.
Sprockets: All Peugeot’s have an 11 tooth front sprocket. 102 rear sprockets have smaller center holes than 103 rear sprockets (because the rear hub is smaller). 103 rear sprockets can interchange with Puch or Motobecane, except for the bolt holes. On both 102 and 103 Peugeot uses a special 5-hole pattern that is unique. They did not want people to easily change to a 6-hole Puch 45 tooth rear sprocket. It can be done with drilling.
Gearing: A smaller rear sprocket makes higher gearing, and higher possible speed. But if the gearing is already optimum, then higher gearing alone will not make any more speed, except on downhills and with tail winds. It takes a greater amount of driving force to push through the air at a greater speed, but higher gearing decreases the rear wheel driving force. So the engine has to make much more torque to achieve the higher speed.
Gearing: 102 and 103 no-variator have the same size front pulley, but the rear pulley is bigger on the 103, about 8 inch, while 102 is about 7 inch. So a 102 rear sprocket must be bigger by 8/7 to have the same overall gearing as a 103. That is why 102 rear sprockets are bigger than 103 no-variator ones.

Enjoy these pages from “CYCLES PEUGEOT – Structures of the Group” May 1977. This 72-page brochure with a plain silver cover, promotes Cycles Peugeot products, for Peugeot products dealers, sellers and business clients.
Peugeot mopeds were made in several different factory locations.
Beaulieu is the main production facility, where Peugeot frames, wheels, and parts were made, and mopeds are assembled.
Saint Louis is where Peugeot engines were made by SMHR.
Dannemarie is where Peugeot magnetos were made, by SMHR.
Cerci la Tour is where Peugeot forks, fenders, racks were made, by SOMENI.
Components like tires, speedometers, switches, lights, brakes were purchased from component makers.
The SMHR Factory at Saint Louis
The Societe Mecanique du Haut-Rhin factory at Saint Louis is where Peugeot engines were manufactured. In 1977 SMHR was producing 3500 moped engines per day.
The SMHR Factory at Dannemarie
The Societe Mecanique du Haut-Rhin factory at Dannemarie is where Peugeot magneto flywheels were manufactured.
The Doubs Factory at Beaulieu
Doubs is the region, Beaulieu is the town. This is the main production center of Cycles Peugeot. Impressive, massive, mind-boggling. What would you call it?

Unofficial Model Names: In 1970 Garelli stopped using engine model names. Instead they spelled out the engine models, like “vertical cylinder two speed automatic”. So these ’70’s and ’80’s engine model names are made up. They are green to distinguish them from official names.
Horizontal Cylinder Engines
1950’s: After WWII much of Europe was damaged. Because gas stations and roads were scarce, Garelli shifted their focus to 50cc lightweight mopeds. In the early 50’s Garelli only made Mosquito horizontal-cylinder friction-drive bicycle engines. They were sold as kits and on bikes. In the late 50’s Garelli also made Mosquito vertical-cylinder chain-drive moped engines. They were only sold on bikes.

Vertical Cylinder Engines
1950’s: In the early 50’s Garelli only made Mosquito horizontal-cylinder friction-drive bicycle engines. They were sold as kits and on bikes. In the late 50’s Garelli also made Mosquito vertical-cylinder chain-drive moped engines. They were only sold on bikes.

1960’s: In ’60-69 engine models had encoded digits:
Digit 1 is always 3.
Digit 2 tells the engine size 4 or 5 is 50 cc, 7 is 100 cc.
Digit 3 tells the speeds 1, 3, or 4 or 7 for 2-speed automatic.
Digit 4+ tells the type, pedal P or kick K.
Digit 4+ R means fan cooled for scooter or 3-wheel truck.

The one shown is foot shift, but the ID says hand shift (Y),
so foot shift must have been an option.
1970’s: Most of the 1960’s engines with rounded engine cases and cylinder fins were discontinued in 1970-71. The cases and fins became more square. Horizontal lines were added to the side covers. Because of that you can tell a 70’s Garelli from a 60’s one by a photo or from 100 feet away.
Engine Models: In 1970 Garelli stopped using engine model numbers. Instead they spelled out the engine models, like “vertical cylinder two speed automatic”.

In Jan 1972 the UK “sixteener law” required 16-year-olds to drive only “mopeds”. The new definition of “moped” was 50cc with pedals, unlimited in power and speed. By late-1972 or early-1973, makers like Garelli added pedals to their 50cc motorcycles.
The book “Funky Mopeds” by Richard Skelton covers these bikes and this period. The UK-model specs and year ranges listed here are from there.

1980’s: In 1978 all vertical cylinder engines changed from type G (Gulp) to type V (VIP). The differences are subtle. The biggest visible difference is the side covers. G type has horizontal lines on top front and bottom front. V type has horizontal lines only on bottom front. G type has a flattened 8-sided sticker in the middle. V type says GARELLI in raised letters. There are internal differences. The transfer ports and base gasket are different. The front lower engine mount was eliminated or unused.
Left is a G2 engine, right is V2.
Left is a G5ak engine, right is M5ak.
