Yamaha hits the trails with the new-and-improved WR250F. Touted as competition-ready right out of the box, the MY18 ’Wide Ratio’ brings a newly-reworked engine in a new frame with other delightful nuggets like the advanced suspension and optional engine-tuning app that uses your smartphone as an interface for quick and easy ignition/injection mapping. Titanium poppets and electronic fuel injection add even more yummy-goodness to the mix as part of the standard equipment package. Will it be enough for the current market? We’ll see soon enough, but meanwhile we can dissect the thing to see what all makes it tick.
