2020 Yamaha FJR1300AS Technical Analysis & Specification Breakdown

Positioned in Yamaha's sport touring motorcycle lineup, the 2020 Yamaha FJR1300AS pairs a 1298 cc (79.2 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 146.2 HP (106.7 kW) at 8,000 rpm while maximum torque reaches 138 Nm (101.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 112.6 HP per liter and a 1,000 rpm working window between peak torque (7,000 rpm) and peak power (8,000 rpm), 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 296 kg (653 lbs) wet (curb), translating to a power-to-weight ratio of 0.49 HP/kg (2.02 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 1,544 mm (60.8 in) wheelbase engineered for planted straight-line stability. The 24.98-liter (6.6 US gal) fuel tank paired with a rated consumption of 6.2 L/100 km provides an estimated theoretical range of roughly 403 km (250 miles) between fill-ups.
