Engineered by Yamaha for the enduro - offroad motorcycle segment, the 2021 Yamaha WR450FSP utilizes a 450 cc (27.5 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 97.0 x 60.8 mm (3.8 x 2.4 inches) with a 13.0:1 compression ratio.
On the scales, the WR450FSP measures 119 kg (262 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 955 mm (37.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 7.9-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
