2011 Yamaha Road Star S Technical Analysis & Specification Breakdown
Built around Yamaha's touring motorcycle platform, the 2011 Yamaha Road Star S 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 8.3:1 compression ratio.
On the scales, the Road Star S measures 337 kg (743 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 709 mm (27.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,689 mm (66.5 in) wheelbase engineered for planted straight-line stability. The 18.17-liter (4.8 US gal) fuel tank paired with a rated consumption of 6.53 L/100 km provides an estimated theoretical range of roughly 278 km (173 miles) between fill-ups.
