Positioned in Yamaha's custom - cruiser motorcycle lineup, the 2021 Yamaha Bolt R-Spec relies on a 942 cc (57.5 cu in) air-cooled v2, four-stroke powerplant. In factory specification, maximum torque reaches 80.4 Nm (59.3 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. 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 R-Spec measures 248 kg (547 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 690 mm (27.2 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 13-liter (3.4 US gal) fuel tank paired with a rated consumption of 4.61 L/100 km provides an estimated theoretical range of roughly 282 km (175 miles) between fill-ups.
Within MotoLibrary's Yamaha archive, this model family spans 9 indexed model years from 2017 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
