Built around Sherco's enduro - offroad motorcycle platform, the 2017 Sherco 450 SEF-R utilizes a 449.4 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 95.0 x 63.4 mm (3.7 x 2.5 inches).
On the scales, the 450 SEF-R measures 109 kg (240 lbs) dry. Rider ergonomics and chassis geometry center around a 950 mm (37.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 9.7-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
