At the heart of the 2009 Vahrenkamp Diesel 462 allround motorcycle, Vahrenkamp utilizes a 462 cc (28.2 cu in) air-cooled diesel layout. In factory specification, peak output is rated at 11 HP (8 kW) at 3,600 rpm while maximum torque reaches 26.3 Nm (19.4 lb-ft) at 2,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 23.8 HP per liter and a 1,600 rpm working window between peak torque (2,000 rpm) and peak power (3,600 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Diesel 462 measures 180 kg (397 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.36 kg per horsepower).
Within MotoLibrary's Vahrenkamp archive, this model family spans 4 indexed model years from 2008 to 2011, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
