517-35 Liste 0 GTS-50 Sport
The 517 GTS Sport with its 4-foot switched engine was a big attention magnet. Where the CS-50 and the GT-50 still had the chrome bushings on the front fork, the GTS50 Sport had fitted large rubber cuff covers around the front fork. Still with a crack starter mechanism, because by Dutch legislation. New were, just for the "looks", two extra frame tubes from the headset to below the engine block. These had no function, but were very nice to see.
Compared to the CS-50 and the GT-50, the GTS-Sport had a 4-foot-switched engine. Motor type 280. GTS means Grand Tourisme Sport.
General GTS-50: The GTS-50 is a moped model from Zündapp and was built in 1972 (as 517 type) until the bankruptcy of Zündapp in 1984 produced in various versions. Air cooling was usually used, but in Germany the GTS with the 284 engine could be delivered from 1978 in a special version (Sondermodell) with 5 gears. The latest versions in 1984 the water-cooled and spie-switched 284-210 engine with 5 gears and a 280 cylinder with 2.9 hp as a moped model. Not delivered here in the Netherlands. On the home market in Germany, the GTS-50 was delivered with the 284 engine as KKR (Klein Kraft Rad). The abbreviation GTS stands for Gussrahmen-Touring-Sport (Casting Frame Touring Sport). Finally, as a model 540, the GTS-50 was delivered with a new engine. This modern engine, type 314, had a claw-switched gearbox. The model 540 was only delivered for half a year, just before Zündapp GmbH went bankrupt. The phenomenal engine block 314 could not prevent this either.
