The SRA 50 Star is a scooter of Samson with an automatic engine Morini . SRA stands for Simson Roller Automatic and the 50 for the maximum speed of 50 km / h. A derived moped variant was called SRA 25. The model name Star is based on the earlier Simson Star , which was not a scooter, but a mokick .

history

When it was released in 1996, the Star 50 was a novelty for Simson. For the first time, a small scooter with a modern scooter look with a central spring strut and a continuously variable automatic transmission was produced, with the 3.7 kW drive unit from Moto Morini . Thanks to separate lubrication, there was no longer any need to fill up with a fuel-oil mixture. The special features of the equipment included a lockable helmet compartment under the seat and a catalytic converter. Optional disc brakes were installed on the front wheel. The cockpit with integrated clock was taken over from the Simson gamma with a few changes. In a single-seat version with a throttled engine, the scooter was also available as a moped under the name Star 25 . Compared to the SR50, the Star 50 was a new development. Similarities can only be seen in relation to the combination of the scooter concept with a telescopic fork .

Despite the many technical innovations and although the advertising advertised it as the only scooter made in Germany , the Star 50 was unsuccessful. In fact, Simson was the only major German manufacturer of mopeds at the time. However, the competitive pressure from cheap foreign scooters was too great. There have been attempts to establish the Star 50 as a police service vehicle in the state of Thuringia . However, the vehicle had design weaknesses. The driving behavior was quite unstable due to a high seating position and narrow tires. In addition, the separate lubrication did not always work properly, which led to corresponding engine damage. Overall, the Star 50 had not been adequately tested when it was released. The market opportunities for German scooters were generally bad at that time, but the Star 50 also did not achieve the sales figures of the SR50 , which was offered at the same time , which was more simply equipped, but mature and inexpensive.

The Star 50 has undergone a series of further development measures. Initially the engine output was 2.8 kW, it was increased significantly to 3.7 kW in 1997. In addition, the rear brake was now operated with the left hand instead of the right foot. Previously, both the throttle and both brakes were located on the right side. In 1999 the scooter was revised on a large scale. Wheels and tires were widened so that the driving behavior improved. The external appearance was carefully modernized, which was particularly noticeable in the rear area on the splash guard, modified exhaust suspension and the smoothed lining of the rear wheel. There were also minor changes to the disc brakes.

Production of this comparatively young model was stopped as early as 2000. The sales success did not meet expectations. The SR50, which was still being built in parallel, remained in the production program. As a replacement for the modern Star 50, so-called SULA motor scooters were imported from Taiwan, which were produced exclusively for Simson, but which ultimately damaged Samson's reputation as a German quality brand.
