Engineered by Yamaha for the enduro - offroad motorcycle segment, the 2022 Yamaha YZ65 utilizes a 65 cc (4 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 43.5 x 43.6 mm (1.7 x 1.7 inches) with a 9.1:1 compression ratio.
On the scales, the YZ65 measures 60.8 kg (134 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 754 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,143 mm (45 in) wheelbase engineered for quick, flickable steering geometry. The 3.41-liter (0.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
