In comparison, the new YZ250F was omnipotent. Its four-stroke engine was super-revvy while still delivering tractable low-end and midrange power, further improved by an FMF MegaBomb header and Factory 4.1 titanium silencer with spark arrestor. All the controls worked lighter, quicker and better than on the old bike, but by far the greatest difference was the chassis. Perched high in a roomy cockpit and with a foot of fully adjustable suspension travel beneath me, the YZ250F could rush headlong into virtually any condition and handle it with aplomb. So rather than the rider having to help the bike, the bike helped the rider. Inarguably, that’s the pivotal difference between the old and new-bike riding experiences.
