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.

In segment context, the Ninja 400's specifications hold up well. Its 168 kg kerb weight undercuts the Yamaha R3 (169 kg) and significantly beats the KTM RC 390 (172 kg). The parallel-twin produces a clear torque advantage over single-cylinder rivals in the real-world mid-range - the bandwidth where daily riding and overtaking actually happen. The one area where numbers disappoint is the instrument cluster: an analogue tachometer with a small digital inset, compared to the Aprilia RS 457's 5-inch TFT and KTM RC 390's colour TFT. The hardware is exceptional; the information display is not.

## FAQs

**What is the engine displacement of the Kawasaki Ninja 400?**
The Kawasaki Ninja 400 uses a 399cc liquid-cooled DOHC parallel-twin engine with an 8-valve head. It produces 44.7 bhp at 10,000 rpm and 37 Nm of torque at 8,000 rpm, paired with a 6-speed gearbox and slip-and-assist clutch.

**What is the fuel efficiency of the Kawasaki Ninja 400?**
ARAI-rated efficiency is 26.7 kmpl. With the 14 L fuel tank, this gives a theoretical range of approximately 370 km per fill. Real-world city mileage in stop-and-go traffic typically returns 22-24 kmpl depending on riding conditions.

**What are the dimensions and kerb weight of the Kawasaki Ninja 400?**
Kerb weight is 168 kg - among the lightest in the 400cc sportbike class. Full dimensions: 1,990 mm length, 710 mm width, 1,120 mm height, 1,370 mm wheelbase, 140 mm ground clearance, and 785 mm seat height.

**Does the Kawasaki Ninja 400 get ABS?**
Yes. Every India-market Ninja 400 comes with dual-channel ABS as standard equipment - there was no non-ABS variant. The ABS covers both the 286 mm front and 193 mm rear petal discs, with a calibration that allows confident progressive braking before engaging.

**What suspension setup does the Kawasaki Ninja 400 use?**
The Ninja 400 runs a 41mm telescopic fork up front and a horizontal back-link monoshock at the rear. Neither unit is adjustable for preload or damping, but both are well-matched to the bike's 168 kg weight for competent performance on typical Indian road surfaces.
