Positioned in Stels's atv motorcycle lineup, the 2023 Stels 100RS relies on a 91.3 cc (5.6 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 7.9 HP (5.8 kW) at 7,500 rpm while maximum torque reaches 8.5 Nm (6.3 lb-ft) at 4,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 86.5 HP per liter and a 3,000 rpm working window between peak torque (4,500 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 100RS measures 142 kg (313 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (17.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,080 mm (42.5 in) wheelbase engineered for quick, flickable steering geometry. The 9.1-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
