1983 KZ750-L3[edit | edit source]

1983 Kawasaki KZ750-L3


Produced for model year 1983, the Kawasaki KZ750 L3 was very similar to the 1982 Gpz750. This is the year during which the Gpzs made the jump towards "sportbikes", while the KZ line branched off as "sport cruisers". This model can be distinguished by the three horizontal stripes along the gas tank and tailpiece, orange, red and yellow, and the lack of fairing typical on GPZ bikes of the same era. The Kawasaki inline-four engines are considered very robust and reliable. Therefore, this motorcycle, and others with similar engines, are sought after for their rideability and repairability.
