The Kawasaki KX450F–SR is the pinnacle of motocross GP technology, with class and race-leading power delivery controlled by state of the art suspension and lightweight high-tech chassis parts. Specially developed by technicians from the Japanese factory’s Akashi race department and the KRT base in Europe, the ‘SR’ model still retains many of the outstanding engine and chassis qualities of the standard KX450F. The bike is raced in the blue riband MXGP (formerly known as MX1) class, against other 450cc four stroke machines. Utilising the latest generation Showa suspension, the machine can be set-up to offer the best bump absorption and stability in the varied terrain experienced by riders across the extensive global MXGP calendar. In 2017 the KX450F–SR is campaigned by KRT Belgian Clement Desalle, French rider Jordi Tixier plus Dixon Racing teamster, the Englishman, Tommy Searle.
