Positioned in Stels's atv motorcycle lineup, the 2021 Stels 600Y Leopard pairs a 594 cc (36.3 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 39 HP (28.5 kW) at 5,500 rpm while maximum torque reaches 56 Nm (41.3 lb-ft) at 4,250 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 65.7 HP per liter and a 1,250 rpm working window between peak torque (4,250 rpm) and peak power (5,500 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 600Y Leopard measures 376 kg (829 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.64 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
