2012 Yamaha Royal Star Venture Technical Analysis & Specification Breakdown
At the heart of the 2012 Yamaha Royal Star Venture touring motorcycle, Yamaha features a 1294.7 cc (79 cu in) liquid-cooled v4, four-stroke configuration. In factory specification, peak output is rated at 97 HP (70.8 kW) at 6,000 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, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
