At the heart of the 2011 Yamaha Worldcrosser prototype - concept model motorcycle, Yamaha relies on a 1199 cc (73.2 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 115 HP (83.9 kW), transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 95.9 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Worldcrosser measures 250 kg (551 lbs) wet (curb), translating to a power-to-weight ratio of 0.46 HP/kg (2.17 kg per horsepower). Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,539 mm (60.6 in) wheelbase engineered for planted straight-line stability. The 22.71-liter (6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
