2012 Yamaha Star Warrior Technical Analysis & Specification Breakdown
Engineered by Yamaha for the custom - cruiser motorcycle segment, the 2012 Yamaha Star Warrior utilizes a 1671.6 cc (102 cu in) air-cooled v2, four-stroke layout. Internal engine geometry specifies a bore and stroke of 97.0 x 113.0 mm (3.8 x 4.4 inches) with a 8.4:1 compression ratio.
On the scales, the Star Warrior measures 294.8 kg (650 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 714 mm (28.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,666 mm (65.6 in) wheelbase engineered for planted straight-line stability. The 15.14-liter (4 US gal) fuel tank paired with a rated consumption of 6.03 L/100 km provides an estimated theoretical range of roughly 251 km (156 miles) between fill-ups.
