The Troll (short for T Ouren roll it) was a scooter model in the GDR . It was built from January 1963 to December 1964 in a number of 56,513 at VEB Industriewerke Ludwigsfelde and was the last model in a series of motor scooters that came from Ludwigsfelde from 1954 . The term troll is a play on words that on the one hand includes the meaning of goblin , on the other hand it was also the abbreviation for touring scooter .

In contrast to Berlin and Wiesel, the Troll model was a completely new design. The backbone was formed by a welded, torsion-resistant sheet metal profile frame. The displacement was 143 cm³, the top speed 90 km / h and the curb weight 122 kg. The chassis was significantly improved by using long swing arms and generously dimensioned spring struts (130/100 mm front / rear) and placed the Troll at the top of international motor scooter construction, although this resulted in a higher seating position than before. The scooter was visually redesigned in the style of the trapezoidal line. In addition to the spring struts, the engine also came from the MZ ES 150, which was released in 1962. Modified and equipped with fan cooling (designation RM150), the Troll with 9.5 HP engine power and 1.25 kpm torque was not only in the GDR, but also internationally most powerful scooter model in its class. A relatively large amount of development work went into the exhaust system, which, in contrast to the Vespa models of the time, did not result in any throttling of the engine output despite the low noise level below 80 dB. Another novelty in motor scooter construction was the first-time use of asymmetrical low beam on the Troll.

The large side flap was practical as access to the engine without having to remove the entire rear hood, as was the case with the previous models. Possible designs of the rear hood and accessibility to the engine were discussed in advance in the trade press in an international comparison. One of the troll's weak points initially was its tendency to swing the handlebars. Therefore, unlike usual, the vehicles produced had to complete a test drive not only on the roller test bench, but also on the road. From September 1963, after extensive investigations into the causes of the handlebar sway, the Troll was equipped with a modified, 1.2 kg heavier swing arm.

In the KFT test , the very stable frame and the good driving performance of the full-throttle-resistant engine were praised, which were even significantly above the factory specifications (99 km / h top speed). Together with the very good suspension properties, good seating position and raised leg shield, which completely protects the legs from wind and moisture, the Troll was confirmed to be a fully-fledged travel scooter in contrast to the previous model. Only the braking effect is not in accordance with the driving performance, and the relatively large weight affects the maneuverability. There was also criticism of vibrations in the handlebars and running board in the absence of an elastic engine mount, and the tendency for the handlebars to swing also occurred on the test vehicle. Finally, the design was criticized because the rounded front section did not match the otherwise stretched line.

The discontinuation of motor scooter production in 1965 seemed premature in view of the newly developed and progressive troll and partly newly set up production facilities. It was the result of a planned economic re-profiling of the manufacturing plant to the exclusive construction of trucks from 1965 (models W50 , L60 ).

The Campi single-track trailer was available as an accessory for the Troll . In the former GDR, the Čezeta , the smaller Tatran S125 and the small scooters from Simson and Jawa were available as scooter alternatives .
