At the heart of the 2019 Yamaha Bolt C-Spec custom - cruiser motorcycle, Yamaha relies on a 942 cc (57.5 cu in) air-cooled v2, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 85.0 x 83.0 mm (3.3 x 3.3 inches) with a 9.0:1 compression ratio.
On the scales, the Bolt C-Spec measures 247 kg (545 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,570 mm (61.8 in) wheelbase engineered for planted straight-line stability. The 12-liter (3.2 US gal) fuel tank paired with a rated consumption of 4.61 L/100 km provides an estimated theoretical range of roughly 260 km (162 miles) between fill-ups.
