Built around Sherco's trial motorcycle platform, the 2017 Sherco 125 XY utilizes a 123.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 54.0 x 54.0 mm (2.1 x 2.1 inches).
On the scales, the 125 XY measures 83.5 kg (184 lbs) dry. Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 3.5-liter (0.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Sherco archive, this model family spans 2 indexed model years from 2016 to 2017, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
