2011 Yamaha Grizzly 125 Technical Analysis & Specification Breakdown

Engineered by Yamaha for the atv motorcycle segment, the 2011 Yamaha Grizzly 125 pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 49.0 x 66.0 mm (1.9 x 2.6 inches) with a 9.0:1 compression ratio.

On the scales, the Grizzly 125 measures 152 kg (335 lbs) wet (curb). 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 1,080 mm (42.5 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
