The Mosquito, introduced in 1995, was designated as the model 585. This was equipped with a two stroke, single cylinder, air cooled engine designed by Slovenian company Tomas. There are a lot of plastic parts in the bodywork with the tank shape and front mudguard position giving it an off-road look. However, with its Italian made cast wheels, Brembo front brake, CZ telescopic forks and adjustable hydraulic rear shocks, it is set up as a very efficient road bike.  The quite powerful engine pulls well all the way through its five gears and the 12 volt electrics give very good light output.
There was also the model shown below, with wire wheels and drum front brake. This had power reduced to 2.7kW (3.6bhp) and a top speed of 40kph (25mph) to comply with EU regulations for mopeds.
Following company changes at Jawa, the Mosquito was dropped in about 1999, in favour of the Dandy Minarelli only for a very similar looking model, the Robby, to appeal a couple of years later.
