Positioned in Buell's naked motorcycle lineup, the 2003 Buell Blast relies on a 492 cc (30 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 34 HP (24.8 kW) at 6,500 rpm while maximum torque reaches 40.7 Nm (30 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 69.1 HP per liter and a 1,000 rpm working window between peak torque (5,500 rpm) and peak power (6,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Blast measures 163.3 kg (360 lbs) dry, translating to a power-to-weight ratio of 0.21 HP/kg (4.8 kg per horsepower). Rider ergonomics and chassis geometry center around a 699 mm (27.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 10.6-liter (2.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
