At the heart of the 2011 Fischer MRX sport motorcycle, Fischer features a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 80 HP (58.4 kW) at 9,500 rpm while maximum torque reaches 52 Nm (38.4 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 123.6 HP per liter and a 2,000 rpm working window between peak torque (7,500 rpm) and peak power (9,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the MRX measures 166.5 kg (367 lbs) dry, translating to a power-to-weight ratio of 0.48 HP/kg (2.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 749 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,397 mm (55 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
