2012 Yamaha Royal Star Venture S Technical Analysis & Specification Breakdown
Engineered by Yamaha for the touring motorcycle segment, the 2012 Yamaha Royal Star Venture S pairs a 1294.7 cc (79 cu in) liquid-cooled v4, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 97 HP (70.8 kW) at 6,000 rpm while maximum torque reaches 115.3 Nm (85 lb-ft) at 4,750 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 74.9 HP per liter and a 1,250 rpm working window between peak torque (4,750 rpm) and peak power (6,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Royal Star Venture S measures 394.2 kg (869 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (4.06 kg per horsepower). Rider ergonomics and chassis geometry center around a 749 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,704 mm (67.1 in) wheelbase engineered for planted straight-line stability. The 22.71-liter (6 US gal) fuel tank paired with a rated consumption of 6.03 L/100 km provides an estimated theoretical range of roughly 377 km (234 miles) between fill-ups.
