The handheld device eliminates the need for a trackside
Lower frame rails have been widened and also contribute to the bikes overall rigidity balance. Forged chain adjusters are also equipped with a self-locking rear axle nut.
Each KX450 motorcycle comes standard with three different couplers, easily allowing riders to select pre-programmed fuel injection and ignition mapping to suit their riding style or track conditions.
The handheld device eliminates the need for a trackside laptop and gives riders the ability to create custom maps for precise adjustment of fuel and ignition settings.
The frame is thinner, there’s updated Showa front forks, and the fuel pump is updated as well. The linkage ratios have been revised to help keep the rear wheel planted for increased traction.There are quite a few other changes; there’s the usual tweaks to top end bits (larger valves, new piston, new finger-follower valve train larger 44 mm throttle body), along with a new hydraulic clutch and header, updated shift drum and shift fork, and new big end bearings.
