The Puch MS 50 is a moped with a displacement of 48.8 cm³ and an output of 1.0 to 1.7 kW. MS stands for moped shell frame, the number 50 stands for the displacement of approx. 50 cm³. The Puch MS 50 was manufactured practically unchanged from 1954 to 1982 by the Austrian manufacturer Steyr-Daimler-Puch , making it the world's longest-built moped.
Model history
Puch began design work for the MS 50 in autumn 1952 and presented the first pre-series model in summer 1954. In autumn 1954, the MS 50 came on the market in a gray-green color. The developer was the engineer Walter Kuttler. The relatively small wheels in comparison to other mopeds at the time such as the NSU Quickly were considered particularly innovative . On the other hand, the design solution of the tank frame connection was rated less positively.
The central tube of the frame , called "Stangel" in Austrian, led to the nickname "Stangelpuch". It was also called “Postler-Puch” or “Postfrosch” because of its long use at the Austrian post office. Other nicknames were "Maurerbock" and "Maurersachs".
The MS 50 and its fan-cooled engine served as a template for most of the later Puch mopeds and small scooters (VS, DS , VZ, MV, MC, X50 and others).
The first series of MS 50 (6000175-6000200) [source required] used the frame of the pre-series model. A striking feature of this model and the second series was the round transition ("bead") from the seat post to the luggage rack. This led to the name "Sicke" -Puch. Later models got an almost straight transition. Other differences were a thinner central tube (“stem”), the small 3-liter tank (later 4.6 l and 5.5 l), thinner rims, non-chrome hubs, a smaller cylinder head and narrower front fenders.
The exact number of pieces of the "bead" Puch is unconfirmed. In the Puchklub.at forum, 6,003,6xx is currently given as the number for the highest confirmed bead. The spare parts catalog indicates a change to the frame, fork, front fender and front wheel from number 6,030,001. However, this may not apply to the "bead".
From 1955 there was the enlarged tank (4.6 l), reinforced moped frame, deeper and wider mudguards, larger tires and rims, a reinforced chain and a new chain cover. The MS 50 has now been painted red. In the same year the luxury version MS 50 L was presented - with chrome-plated rims, hubs and tool box lids as well as white wall tires. The MS 50 L was available in lime green, red and black.
In 1956 the MSK 50 moped scooter was introduced (K stands for Kickstarter). It had the rear fenders of the later model with full hub (VS 50) as well as leg protection and running boards of the VS 50 K. The engine was not throttled and made 2.3 HP.
In 1958 the MS 50 V model came onto the market (V stands for reinforced). It had the large tank (5.5L) and the more powerful rear shock absorbers of the full-hub model (VS 50).
The names MS 50, MS 50 L and MS 50 V were used in different markets at the same time. There was a multitude of other models such as the MS 25 moped version, throttled to 25 km / h. This multitude of products, designs and markets makes a comprehensive listing of all models and years of construction almost impossible. In 1961, for example, there were the models MS 50 VK (with kick starter) and MS 50 VKF (with kick starter and foot control) in Sweden. 1968 a catalog shows the MS 50 A (with 2-speed automatic) and MS 50 KA (with 2-speed automatic and kick starter). In Great Britain there was the MS 50 D (three-speed) with a VS frame, bench seat, but a front MS fender. In Denmark there was the MS 50 P (pedals), MS 50 K2T and MS 50 K3T (with kick starter and bench).
Puch also manufactured the MS 50 under the Allstate brand for the department stores Sears Roebuck and Co. USA and Simpson-Sears Ltd. Canada .
From the end of the 1950s, the Slovenian company Tomos also built MS and VS models, which were initially assembled under license; later models were then produced in-house under the name "Colibri". This was the beginning of the successful Tomos moped program.
The Italian vehicle manufacturer Bianchi built the MS 50 under the name Bianchi Sparviero under license (1956).
