2014 Yamaha YZ250F Quick Ride
Yamaha stuck with its proven KYB SSS Speed-Sensitive System suspension for 2014, now on both the 450 and 250 MX platforms.
Ditching its carbureted past, the 2014 YZ250F now has a fuel injection system with 12-hole injector and 44mm throttle body.
"The new YZ250F has enormously improved in the motor department, gaining a lot of power in the mid-range and top-end," says MotoUSA tester Chris See.
The YZ250F's Single retains the 77mm bore and 53.6mm stroke from the previous model year, but the reversed engine layout flips the intake to the front. As a result, the airbox and filter have been relocated to where the fuel tank normally rests.
The rear-facing engine and air intake configuration relocate the 2.1 gallon fuel cell to under the seat, and the exhaust header wraps around the engine.
Thanks a repositioned fuel cap, the 2014 YZ250F is easier to slide around on during motos.
The rear KYB shock has been retuned and the reservoir position has been flipped to accommodate the wrap-around exhaust.
Rather than turn to air forks like others in the class, the 2014 YZ250F retains the KYB Speed-Sensitive System suspension. The front forks have a more rigid outer tube, though, and a new coating on the inner surface.
Chris See got along with the base braking package, unchanged from the previous model. "I wish the rear was a bit stronger," says See. "You really had to mash on the pedal to get it to stop when it got hot."
Brakes out front were unchanged from the previous model, but according to See it wasn't a problem. "You can really grab a handful of brake and not worry about the front end tucking."
Though he had limited time on the bike, See feels the 2014 YZ250F is a definite improvement over the previous year's model.
"The bike feels rather wide compared to the 2013 model, but only in the tank area," explains See. "The rear end of the bike feels average size."
The 2014 YZ250F felt high in the rear when coming into corners, like it didn't want to settle in ruts. Our tester took out a half turn on the high-speed compression on the shock, which helped alleviate the sensation.
Due to such a short ride, our tester wasn't able to tweak the suspension settings as much as he'd have liked.
"The bottom is average to most of the current 250 models, but it really does come alive in the mid-range," says See. "It was a pleasure to get into the loamy berms and have it pull you out in a wheelie."
The 2014 YZ250F will retail for $7940 and will be offered in Yamaha Blue/White (as tested) and White/Red colorways.
