At the heart of the 1975 Can-Am TnT 250cc enduro - offroad motorcycle, Can-Am pairs a 247 cc (15.1 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 29 HP (21.2 kW) at 8,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 117.4 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 TnT 250cc measures 119.8 kg (264 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.13 kg per horsepower). Rider ergonomics and chassis geometry center around a 838 mm (33 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,397 mm (55 in) wheelbase engineered for quick, flickable steering geometry. The 9.5-liter (2.5 US gal) fuel tank paired with a rated consumption of 8.4 L/100 km provides an estimated theoretical range of roughly 113 km (70 miles) between fill-ups, while factory top speed is listed at 129 km/h (80 mph).
