Six World Championships
Kawasaki's superbike dominated World Superbike for most of a decade, and the road bikes that followed carry the same architecture into club racing every weekend.
Check the Immobiliser First
Where the key carries a transponder, the ring around the barrel is part of the starting circuit. That has to be settled before the barrel comes off.
Not for a Road Bike
A registered motorcycle needs its steering lock and, in most places, its immobiliser. This part assumes the machine is used away from public roads.
Starting the Bike
The starter button stays where it was on the switchgear. This part replaces the ignition block and not the controls around it.
Keyless Between Sessions
No fumbling with gloves on, no key left in a barrel while the bike sits on stands, and nothing to lose in a paddock full of people.
Storage
The original block belongs in a dry bag with its key. A seized barrel and a lost key together cost more than this part did.
Transponders
If the key talks to the engine controller, the aerial around the barrel is part of the starting circuit. Establish that before ordering, because the fix is separate.
Position on the Yoke
The new body occupies the same footprint, so the tank, the top clamp and the instruments all keep their relationship to each other.
Gloves On
The button is sized and sprung to be usable with racing gloves, which is not a given on switches bought by the metre.
What It Is Not
It is not a security device, not a performance part and not a road modification. It removes a lock that a trailered motorcycle has no use for and takes some weight off the worst place on the chassis to be carrying it.
