At the heart of the 1967 Pannonia P20 classic motorcycle, Pannonia utilizes a 246 cc (15 cu in) air-cooled twin, two-stroke layout. In factory specification, peak output is rated at 22 HP (16.1 kW) at 7,500 rpm while maximum torque reaches 21 Nm (15.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 89.4 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 P20 measures 156 kg (344 lbs) wet (curb), translating to a power-to-weight ratio of 0.14 HP/kg (7.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 16.5-liter (4.4 US gal) fuel tank paired with a rated consumption of 4.2 L/100 km provides an estimated theoretical range of roughly 393 km (244 miles) between fill-ups, while factory top speed is listed at 130 km/h (81 mph).

Use this page to compare this motorcycle by its real specifications, not only by model name. Focus on the details that affect fit, comfort, handling, range and ownership.
Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
