Technical Overview
2001 VOR 503 Supermoto SM Technical Analysis & Specification Breakdown
Engineered by VOR for the enduro - offroad motorcycle segment, the 2001 VOR 503 Supermoto SM utilizes a 503 cc (30.7 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 56 HP (40.9 kW) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 111.3 HP per liter, 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 503 Supermoto SM measures 109 kg (240 lbs) dry, translating to a power-to-weight ratio of 0.51 HP/kg (1.95 kg per horsepower). Rider ergonomics and chassis geometry center around a 940 mm (37 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
