This was better known as the Z650 Custom. It was only offered in the UK in one color metallic stardust silver, the same color as the recently launched Z1-R. The motor was a standard B2 unit but the custom was much modified elsewhere. Kawasaki fitted seven spoke alloy wheels with twin disks up front and a disk at the rear. The bold new graphics made this model stand out from the crowd and the C was a very good seller. The first batch of bikes in the UK came with a free color matched helmet. This model was only offered in certain markets so may not have been available in your particular country.

The C3 was the first Kawasaki model to use the new all weather sintered disk pads and braking in the wet was much improved. The bike was once again only offered in one color, luminous dark blue. The Speedo now incorporated km/h markings as well as MPH and the rear caliper was changed to accept the new square sintered pads. The side panel badges were also slightly changed. Many considered the C3 to be the best of the range. This was the last of the C range in the UK although there was a C4 elsewhere, available in black or red.
