Built around Stels's atv motorcycle platform, the 2021 Stels 800G Guepard pairs a 800 cc (48.8 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 67 HP (48.9 kW) at 7,000 rpm while maximum torque reaches 73 Nm (53.8 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 83.8 HP per liter and a 2,000 rpm working window between peak torque (5,000 rpm) and peak power (7,000 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 800G Guepard measures 410 kg (904 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.12 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,550 mm (61 in) wheelbase engineered for planted straight-line stability. The 26-liter (6.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
