1960 Zündapp 250 S Trophy Technical Analysis & Specification Breakdown

Engineered by Zündapp for the allround motorcycle segment, the 1960 Zündapp 250 S Trophy relies on a 245 cc (15 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 14.5 HP (10.6 kW) at 5,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 59.2 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
