2018 Yamaha XVS650 A Technical Analysis & Specification Breakdown
Engineered by Yamaha for the custom - cruiser motorcycle segment, the 2018 Yamaha XVS650 A relies on a 649 cc (39.6 cu in) air-cooled v2, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 81.0 x 63.0 mm (3.2 x 2.5 inches) with a 9.0:1 compression ratio.
On the scales, the XVS650 A measures 247 kg (545 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,625 mm (64 in) wheelbase engineered for planted straight-line stability. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 4.76 L/100 km provides an estimated theoretical range of roughly 336 km (209 miles) between fill-ups.
