Simson S51: a legendary moped bike from Suhl part 2 #blogpost

Last time, a long time ago, I explained the S51N, and today I will continue the list with 4 other variants. Here they are.

Variants

S51B 1-3: This model has got a big enhancement, which is a pair of blinkers. (It’s sad to know that a lot of B-s lost their indicators) This is why it has a B in it’s name. All of the things on this variant are available on all versions except the S51N and the S51E/4. It has a 3 speed gearbox, a pair of rear footrests, a handle on the seat, a battery, an ignition- and combined switch, an electric horn and a place you can put stuff on. It has a pair of 16 inch aluminum wheels from the older, higher-spec S51s. In front, there is a 6V 25/25W headlight. The popular colours were red, orange, bright and dark green, and after they stopped the production of the S51N, it was available in blue. Until the first half of 1987, it was equipped with a dial that shows up to 100km/h that includes a metal needle, but after it, they changed it to a plastic needle. They stopped poducing it in 1988.

S51B 1-4: It’s nearly similar to the S51B 1-3, but it has 4 gears. It was manufactured in 360 600 models, the most popular S51.

S51B 2-4: The number 2 meant it was equipped with a thyristor ignition system. It was more commonly known as S51 Electronic. It had a more powerful front headlight (6V 35/35W), black rear telescopes and the front telescope got some rubber on it from 1983. (To cover the telescope) Until 1985, it’s signature colour was green, but since 1986, it was available with more colours. From ‘83, it had the Enduro’s comfy seat and in ‘86, they changed the bended kickstarter to the Enduro’s straight kickstarter. It was equipped with a 4-gear transmission and until 1985 it had a BVF 16N1-11 carburetor, and in 1986, it was made with a BVF 16N3-4 carburetor due to the strict emission rules. Like the B 1-3, it had a metal needle until the first half of 1987, and after it had a plastic needle. Until 1987, it had K-30 rubber, and in ‘88, it had K36/1 tyres.

S51E: The word Enduro is the short form of the word “endurance”. This model was introduced in the winter of 1981. The main difference is the lifted exhaust which had a protective net and a wider front right footrest because of the exhaust. It also had a chrome 90mm rear suspension which is known for it’s smooth ride. Because it is designed to be ridden off-road, it had Pneumant K32 off-road tyres. It had a straight, retractable kickstarter, a higher steering “rod” and a thyristor ignition system. It also had 2 rods over the engine block for stiffening the body. It had a rubber cover on the telescope from the start and it had a rear fender which is 5cms (2in) shorter than the other models’ fenders. It’s main colour was silver until 1988, and in 1986 it has got more clolurs like red, bright and dark green. It had the carburetor and needle changes just like the B 1-3 or B 2-4. Until 1988, it had a 6V system, but after January 1989, it had a 12V system (S51/1E1).

Thank you for reading! Next time I will write about the S51C and the S51/1B.
