Learn About The All-New Everything On The 2019 Kawasaki KX450F
After months of anticipation, stoked by the early spy photos we captured at the opening round of the 2018 All Japan MX Nationals, the latest version Kawasaki KX450F has finally been revealed. For the new model year, the Japanese brand completely reworked their aluminum frame and four-stroke engine, loaded both ends with updated Showa suspension, and made components like a Nissin hydraulic clutch and an electric starter part of the production machine. During the initial reveal of the 2019 Kawasaki KX450F, Ken Essex gave a quick rundown of the new parts and explained the technical traits of the big thumper.
