Four Cylinders in Four Hundred Cubic Centimetres

Nobody else builds this. Kawasaki put a genuine inline four into a small-capacity sportbike, gave it a 16.000 rpm ceiling and a ram-air intake, and produced a motorcycle that sounds like a 1990s supersport machine and costs a fraction of one. It is an entirely irrational product and a wonderful one.

A Bike That Has to Be Revved

The ZX-4RR makes its power at the top and expects the rider to keep it there. That means constant gear changes, constant attention and very little spare capacity for hunting a control on the handlebar. The case for a cluster with defined edges is stronger here than on a torquey twin.

What the Left Cluster Carries

Indicators, horn, beam and the navigation of a full colour display with riding modes and traction control behind it. Kawasaki did not simplify the electronics because the engine is small, so the button count matches a much larger motorcycle.

Sealed for Everyday Use

Small sportbikes do a great deal of ordinary riding between track days. The elements are sealed units and the housing is one piece, so a wet commute does not begin the slow deterioration that ends with a vague indicator switch.

Two Finishes

Black and titanium. Against the ZX-4RR's green and black bodywork both are restrained, which suits a cockpit already occupied by a fairly large display.

A New Model

The bike has been on sale a short time and the aftermarket around it is still forming. Properly engineered parts are worth taking when they appear rather than adapting something intended for the Ninja 400, which is a different motorcycle electrically.
