Kawasaki KX125

The Kawasaki KX 125 was first introduced in 1974 and for many years was only available in the North American market. Since 1988, the model has appeared in the markets of Europe and Japan, and since 1990 - in Australia.

The model is the "little brother" of Kawasaki KX 250 and has a lot in common with it - in particular, the frame and chassis. Even the updates of both models took place in the same years.

Despite the long history of Kawasaki KX125 production and a huge number of generations, models should be considered starting from 1990 - it was then that the motorcycle received an inverted fork and features of modern cross-country models. In addition, earlier versions are hardly available on the market.

The Kawasaki KX125 features a 2-stroke liquid-cooled engine with a power valve system (KIPS), a steel half-duplex frame, adjustable sports suspensions, disc brakes, 21 'and 19' wheels, an 8.5 liter fuel tank, 6-speed Gearbox and 87 kg dry matter.

2008 was the last year of production of the model, after which it finally left the market and did not receive further development. Instead, a 4-stroke modification Kawasaki KX250F was introduced.

• Honda CR 125 R
