2019 Kawasaki Z 400 Overview

For 2019, Kawasaki offers the Z 400 as a naked bike motorcycle with 399 cc on tap. The 2019 Kawasaki Z 400 is built around a Four stroke, parallel twin, DOHC, 4 valves per cylinder engine, a compression ratio of 11.5:1. Out on the road, the Z 400 delivers 33.4 kW of peak power and 38 Nm @ 8,000 rpm of torque. In everyday use, the 2019 Z 400 tips the scales at 167 kg, carries a 14-litre fuel tank, offers a seat height of 785 mm and spans a 1370 mm wheelbase. That's roughly 41.5 kg lighter than the average naked bike motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2019 Kawasaki Z 400 spec sheet below.

2019 Z 400 - Pros & Cons

Strengths

Strong power output: Peak output on the Z 400 is 33.4 kW and 38 Nm @ 8,000 rpm of torque - strong numbers for what it is.

Considerations

Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.

Wear Points & Servicing Notes

Cooling system servicing

With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.

Brake disc and pad wear

Single 310mm semi-floating petal discs. Caliper: Single balanced actuation dual piston up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by 41mm Telescopic fork up front and Bottom-Link Uni-Trak, gas-charged shock with adjustable preload at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Chain final drive on the Z 400 means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.

Frame & chassis check

The Trellis, high-tensile steel chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

Z 400 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2019 Kawasaki Z 400 should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept Z 400 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a Z 400's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Carburetor upkeep

A Z 400 that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.
