Positioned in Sherco's super motard motorcycle lineup, the 2025 Sherco 125 4T SM-RS Factory relies on a 124.5 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 52.0 x 58.6 mm (2.0 x 2.3 inches).
Rider ergonomics and chassis geometry center around a 898 mm (35.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,408 mm (55.4 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
