Engineered by Sherco for the trial motorcycle segment, the 2019 Sherco 125 ST-R features a 123.7 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 54.0 x 54.0 mm (2.1 x 2.1 inches).
Rider ergonomics and chassis geometry center around a 685 mm (27 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,322 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 2.4-liter (0.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
