Built around Riedel's allround motorcycle platform, the 1948 Riedel Imme R100 features a 99 cc (6 cu in) air-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 4.5 HP (3.3 kW) at 5,800 rpm, transferring power to the rear wheel through a 3-speed gearbox and chain final drive. With a specific output of 45.5 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
