The Jawa models Kyvacka, including many variants, are distinguished by the evolved headlight nacelle, the fuller, more deeply valanced mudguards, and the use of a swinging rear fork suspension. The name "Kyvacka" means swinger in the czech language. These models employ a sheet metal fairing arrangement that covers the midsection of the motorcycle and provides a unifying element that makes the machine easy to keep clean and is quite handsome in appearance.

To most Jawa/CZ enthusiasts, the engine unit holds particular appeal. The lovely alloy castings that comprise the motors shape respond well to polishing paste and cloth, and may be buffed to a bright finish. The cast alloy carburetor cover is finned to provide an extension to the finning of the crankcase where they meet, and gives a homogenous overall effect to the package. The combined kick and shift lever is another neat feature of the Jawa. In the horizontal position it serves as a gearchange. Push in on the hub, rotate clockwise, and it does double duty as the kickstarter.

The headlight nacelle is one of the major styling features that help to make these machines unique. Enclosing the entire steering head area, and incorporating the speedometer set into the top , the effect is very appealing to say the least. The typically low, rather narrow european style handlebars emerge from holes provided in the sides of the nacelle and the angle of the headlight may be adjusted by a small knurled knob located on top of the headlight rim.
