At the heart of the 2005 Sherco 2.5 trial motorcycle, Sherco features a 249.7 cc (15.2 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 72.8 x 60.0 mm (2.9 x 2.4 inches).
On the scales, the 2.5 measures 69.5 kg (153 lbs) dry. Rider ergonomics and chassis geometry center around a 635 mm (25 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,332 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 2.3-liter (0.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
