About the Kawasaki Ninja 400

Overview

The Kawasaki Ninja 400 is a sports motorcycle from Kawasaki. It was launched in 2018 and has since been discontinued (production ended around 2024). Mechiee still services it at your doorstep. Sports bikes put performance first, usually with a sportier riding position and sharper handling than everyday bikes. With a 399 cc engine it sits in the 250–450 cc class.

Engine and performance

Power comes from a 399 cc twin-cylinder liquid-cooled fuel-injected engine that makes 45 PS at 10,000 rpm and 37 Nm of torque at 8,000 rpm. Its bore is wider than its stroke (70 mm x 51.8 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 268 PS per tonne; by that measure, it is genuinely fast, well beyond everyday traffic speeds. The claimed top speed is 169 km/h. It has electric start.

Gearbox

It has a 6-speed manual gearbox with a 1-down, 5-up shift pattern, and a chain carries drive to the rear wheel. Its slipper clutch lightens the lever and stops the rear wheel hopping when you downshift hard.

Chassis, brakes and tyres

Its frame is trellis, High-Tensile steel. Suspension is by telescopic fork / 120 mm at the front and swingarm / 130 mm at the rear. Braking is by a 286 mm disc at the front and a 193 mm disc at the rear, with dual-channel ABS. ABS on both wheels keeps either tyre from locking under hard braking. It rides on 17-inch alloy wheels with tubeless tyres — 110/70-R17 at the front and 150/60-R17 at the rear.

Size, comfort and range

The seat is 785 mm off the ground, which is about average and suits most riders. It weighs 168 kg ready to ride. Ground clearance is 140 mm — adequate, though tall speed breakers need care. It is 1,990 mm long, with 1,370 mm between the axles. Its 14 L fuel tank and claimed mileage of 26.7 kmpl work out to roughly 374 km per tankful on paper; real-world range is usually lower.

Features and equipment

Equipment includes an analogue and digital instrument console, an LED headlamp and windscreen. Safety equipment includes engine kill switch, side-stand warning, hazard light switch and automatic headlamp on.

Who it suits

It is best suited to riders who want performance and sharp handling. Its low seat also makes it approachable for shorter and newer riders. With this much performance, it is better as a step-up bike than a first bike.

Care notes for this model

Its chain drive needs regular cleaning, lubrication and slack adjustment.

Maintaining the Kawasaki Ninja 400

  • Routine servicing

    Follow the schedule in the owner's manual for your exact variant and year. A regular service is the cheapest way to catch small problems before they become expensive ones.

  • Engine oil & filter

    Engine oil is the single most important consumable to keep fresh. Top up between services if the level drops, and change it on schedule.

  • Brake inspection

    With Disc, 286 mm and Disc, 193 mm brakes, check pad or shoe wear, lever and pedal free play, and braking feel at every service.

  • Chain cleaning & lubrication

    A clean, correctly tensioned and lubricated chain lasts longer and wastes less power. Check slack regularly, especially after riding in rain or dust.

  • Coolant & cooling system

    A liquid-cooled engine relies on coolant. Check the level and look over hoses and the radiator for leaks or damage, and replace coolant as the owner's manual directs.

  • Air filter & spark plug

    A clogged air filter or worn spark plug shows up as hard starting, weak throttle response and poorer fuel economy. Both are checked at a regular service and replaced when worn.

  • Disc brake fluid

    Brake fluid absorbs moisture over time, which lowers its boiling point. Have its level and condition checked and change it on the interval in the owner's manual.

  • Tyre inspection

    This bike runs 110/70-R17 / 150/60-R17 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.

  • Battery & electricals

    The battery is listed as Maintenance Free. Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.

Kawasaki Ninja 400 specs explained

What the technical terms on this page mean.

ABS
Anti-lock braking system. It stops a wheel locking up during hard braking so the rider can keep steering. A single-channel system works on one wheel, usually the front; a dual-channel system works on both.
Fuel injection
Petrol is delivered by an electronically controlled injector instead of a carburettor, which helps with easy starting and steady fuel economy.
Liquid cooling
Coolant circulates through the engine and a radiator, keeping temperatures steadier than air alone, especially in traffic or under load.
Assist and slipper clutch
The assist part makes the clutch lever lighter. The slipper part eases the rear wheel's tendency to hop when you shift down hard.
Trellis frame
A frame built from tubes arranged in triangles, which gives strength without much weight.
Tubeless tyres
Tyres with no inner tube. A small puncture usually loses air slowly, which makes roadside repair easier.
Kerb weight
The weight of the bike ready to ride, with its fluids and fuel, but without a rider or luggage.
Bore x stroke
The cylinder's width and the piston's travel. A larger bore relative to stroke tends to favour revs; a longer stroke tends to favour low-speed pull.
Compression ratio
How much the fuel-air mixture is squeezed before it is ignited. It is one of the factors behind an engine's efficiency and power.
