1960 Pannonia TL250B Technical Analysis & Specification Breakdown

At the heart of the 1960 Pannonia TL250B touring motorcycle, Pannonia relies on a 247 cc (15.1 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 14 HP (10.2 kW) at 5,100 rpm while maximum torque reaches 21 Nm (15.5 lb-ft) at 4,300 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 56.7 HP per liter and a 800 rpm working window between peak torque (4,300 rpm) and peak power (5,100 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the TL250B measures 146 kg (322 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.43 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 110 km/h (68 mph).
