Positioned in Yamaha's sport touring motorcycle lineup, the 2008 Yamaha FJR1300AS features a 1298 cc (79.2 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 141.5 HP (103.3 kW) while maximum torque reaches 134.4 Nm (99.1 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 109 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 FJR1300AS measures 268 kg (591 lbs) dry, translating to a power-to-weight ratio of 0.53 HP/kg (1.89 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,545 mm (60.8 in) wheelbase engineered for planted straight-line stability. The 25-liter (6.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
