Ninja 400 Specifications

The Kawasaki Ninja 400's engine is where the story starts: a 399cc liquid-cooled parallel-twin with DOHC eight-valve architecture and a 180-degree firing order that gives it a linear, addictive power delivery. Maximum power is 44.7 bhp at 10,000 rpm - the engine pulls cleanly from 3,000 rpm and surges with intent above 7,000 rpm on an open highway. Torque peaks at 37 Nm at 8,000 rpm, transmitted through a six-speed gearbox with a slip-and-assist clutch fitted as standard on every unit.

The lightweight trellis frame - conceptually inspired by the Ninja H2 - is central to the Ninja 400's biggest advantage: a kerb weight of just 168 kg. That is lighter than many 150cc bikes and dramatically below the competition in the 400cc class. Combined with a 1,370 mm wheelbase and 140 mm ground clearance, the chassis feels neutral and forgiving - easy to place accurately in corners, composed over mid-corner bumps.

Suspension is a 41mm telescopic front fork and a horizontal back-link monoshock at the rear. Both are non-adjustable but well-calibrated for the bike's weight and intended use. Braking is via a 286 mm front petal disc with a radial-mount caliper and a 193 mm rear petal disc, governed by dual-channel ABS. The ABS calibration is notably progressive - it intervenes late enough to feel like a safety net rather than a constant intrusion.

Tyres are 110/70-R17 front and 150/60-R17 rear - both radials - which keeps unsprung weight low and provides confident wet-weather traction in urban conditions. Fuel efficiency is ARAI-rated at 26.7 kmpl; with a 14 L tank that gives a theoretical range of roughly 370 km per fill. Seat height is 785 mm, accessible for most Indian riders without tiptoeing.
