Engineered by Zündapp for the scooter motorcycle segment, the 1962 Zündapp Bella R203 pairs a 198 cc (12.1 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 10 HP (7.3 kW) at 5,200 rpm, transferring power to the rear wheel through a 4-speed gearbox. With a specific output of 50.5 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Bella R203 measures 147 kg (324 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.7 kg per horsepower). The 8.5-liter (2.2 US gal) fuel tank paired with a rated consumption of 3.3 L/100 km provides an estimated theoretical range of roughly 258 km (160 miles) between fill-ups, while factory top speed is listed at 90 km/h (56 mph).
