THIS IS A 2019 KAWASAKI KX 450!Racing Junks drop down list is wrong and does not have the correct engine size.
The 2019 Kawasaki is all-new and the list of changes is much longer than what isn't new. The motor, frame, suspension, and bodywork are all new—pretty much the whole motorcycle!
The motor in the 2019 Kawasaki KX450 is completely new. With the changes the motor is also physically smaller and lighter. The cams are now finger-follower style that allows for higher revving. Last year's motor was good. It was extremely strong off the bottom end into a hard hitting mid range. For 2019, the KX450 is both easier to ride and faster!
At low rpm, the new KX450 pulls smoother with none of the previous harshness. From there, the transition into the mid range is seamless and it revs out much farther than before. In the whole rpm range, the motor has a freer revving feel. It doesn't feel as tight or harsh as the old motor. The powerplant almost feels like a smaller bore motor with the power of a larger motor. It is just plain easier to ride, which in turn lets you ride more aggressively going faster. This seems to be the direction most manufactures are going with 450s.
As with the KX450F in previous years, Kawasaki offers three couplers to change the power delivery of the new KX450. The three choices are based on terrain—Standard, Hard and Soft.
With the new motor, Kawasaki completely eliminated the kickstart to save weight and added a lightweight electric starting system. To put it simply the system, with a lithium-on battery, works perfectly. It always starts quick and easy.
