Where Riders Learn to Race

The Ninja 400 is the machine a very large share of European racers start on, and the classes built around it are taken seriously by everyone in them. Preparation on these bikes is not casual, and neither is the equipment fitted to them.

A Cluster Without Road Controls

Indicators and horn are gone, and what remains is mapped by the MECTRONIK dashboard: page, mapping, lap marker. Fewer buttons, spaced further apart, identified by position rather than by symbol.

Learning on Data

A rider early in their career benefits from data more than an experienced one does, because the gap between what they think they are doing and what they are actually doing is larger. That is the real argument for a logger on an entry-level motorcycle.

What the Racing Harness Changes

It removes the lighting circuits, the indicator relays and the immobiliser, and replaces the wiring with a loom built for the dashboard. The switch plugs into that. It is a bigger job than fitting the switch and has to be done first.

Not Interchangeable

JetPrime lists separate left-hand switches for MECTRONIK and I2M installations on this bike. They are different products with different internal wiring, and no adapter exists between them.

Built Above the Class

Milled Ergal 7075 with sealed contacts, which is superbike construction on a 399 cc motorcycle. On a bike that will be raced for two or three seasons and then sold to the next rider, that durability is the point.

Machined Edges Under Pressure

A rider early in a race is busy in a way an experienced one is not, and the margin for fumbling a control is smaller. The step around each button gives the thumb something definite to work from when everything else is happening quickly.
