In the same way Japanese automakers are renowned for their reliability and quality, Japanese motorcycle manufacturers are too. One of the big three is Kawasaki which has been making motorcycles for a long time with a racing heritage that makes the brand all the more popular.
But these two factors aren't the only things that make a Kawasaki a good motorcycle. Kawis are always at the forefront of new technology and their engines perform quite well without being too expensive to maintain or run. You essentially get a nice blend of performance, reliability and economy with neither of the three being on top. This is why protecting a Kawasaki bike is crucial.
