Editing Kawasaki Z650

This [[four-stroke]] four-cylinder [[motorcycle]] boasted double overhead camshafts just like the bigger Z1 and Kawasaki claimed 64 BHP from the 652cc motor. Unlike the Z1, the 650 used a plain bearing [[crankshaft]] and used a primary [[chain drive|drive chain]] instead of a gear driven unit. A single 245mm [[disk brake|disk]] was used up front with a 250mm [[drum brake|drum]] on the rear, more than enough to handle this relatively lightweight bike. It was offered in two colors, candy super red or candy emerald green, the green proved very popular in the UK.

Two colors were offered for 1978, luminous dark blue or luminous burnt red. These proved to be unpopular and the B2 sold no where near as well as the B1. Very few other differences were made to the B2. The front brake [[caliper]] was reversed to the back of the fork leg and the front [[master cylinder]] was changed from a round item to a triangular one. The [[charging system]] was changed from a three-phase system to a two phase and the regulator and rectifier was now a combined unit. The cam chain tensioner was changed to an automatic unit and a hazard switch was added to the left-hand switchgear. [[Needle roller bearings]] were now used in the [[swingarm]] instead of the previous model bushes and slight modifications were made to the carbs to improve low speed operation. The fuel tap was replaced with a [[diaphragm]] type unit. There were also slight detail changes to the outer engine cases to incorporate the new lower case Kawasaki logo. The front footrests were now rubber mounted to combat vibration and the front forks were slightly modified.

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 [[Motorcycle helmet|helmet]].

The only difference over the B2 model was a change of graphics and a return to the original green and red colors. Sales once again picked up. The new lower case tank badges were also used. This time the red color was described as candy persimmon red.   

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 [[Miles per hour|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.

Rumour was that the SR stood for 'STATESIDE REPLICA' and this was what Kawasaki thought a replica should be!. It was basically a C3 with slightly '[[Chopper (motorcycle)|chopper]]' styling. [[Chrome plating|Chrome]] plating was used on the [[headlamp]] shell, clock lowers and chain guard. The rear tailpiece was dropped in place of a painted rear fender. The front exhaust downpipes were crossed over and the mufflers were made a bit shorter. Only one color was offered in the UK, midnight blue which was really a purple color although other countries got a red version as well. The rear wheel was now a small but fat 16-inch item for that all-important custom look. In America there was also a D1 in 1978 and an E model, which were very similar but did not have as much equipment, having only one disc at the front and a drum rear brake.

The only difference over the D2 was a change in color and graphics. It was now offered in regal blue. France was still offered the midnight blue as an option.   

The F1 was basically a cross between a C and a B model. It had the alloy wheels but kept the drum brake at the rear instead of a disk. It was offered in three colors, blue, red or green.   

The F2 was much modified over the F1 model. It incorporated many of the larger Z750E parts. The motor was now finished in black and used CDI ignition instead of points. The front end from the 750E was grafted on meaning a change to the brakes, front wheel and clocks. It was offered in three colors, red, green or blue. The [[Kick start|kick-starter]] pedal and shaft was removed from the engine just like the Z750E. A passenger grab rail was also fitted.

There was one major change for 1982, CV carbs were fitted. The larger 32mm carbs also needed the air box assembly from the Z750E/L models. The F3 was offered in two colors, ebony or passion red. The front fender was now also painted to match the rest of the bodywork.   

This was the last of the 650 models, Kawasaki was now concentrating on the GPZ range and there was no place for this previous best seller. The F4 was offered in two colors, galaxy silver or candy wine red. The outer engine cases were similar to the Z750L model.
