Engineered by Yamaha for the naked motorcycle segment, the 2018 Yamaha Niken utilizes a 847 cc (51.7 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 115 HP (83.9 kW) at 10,120 rpm while maximum torque reaches 61.5 Nm (45.3 lb-ft) at 8,480 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 135.8 HP per liter and a 1,640 rpm working window between peak torque (8,480 rpm) and peak power (10,120 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
The 18.17-liter (4.8 US gal) fuel tank paired with a rated consumption of 5.35 L/100 km provides an estimated theoretical range of roughly 340 km (211 miles) between fill-ups.
