Commence in the engine room, where broader, more usable power and crisper throttle response is on tap across the rev range, thanks to reshaped exhaust porting and combustion chamber volume, a modified YPVS power valve, all-new reed-valve petals and revamped carb settings. And, like its YZ250 sibling, lighter, more responsive chassis performance comes via a lighter-weight swingarm and stiffer frame, revised fork and shock internals, light Excel rims, and lighter, stronger brakes.
