2014 Yamaha YZ250F – First Look Brand-new, fuel-injected engine does a 180.
If you’ve studied Yamaha’s family tree in the past number of years, you've probabably heard the YZ450F and YZ250F motocrossers aren’t even related. Sure, they appear a bit alike because of their similar graphics and palettes, but in the surface their DNA was clearly quite different.Except for now. The 2014 Yamaha YZ250F has developed into a slightly smaller version from the radical the feds, replete having a rearward-leaning cylinder which includes the intake in the front and exhaust in back. What’s more, the ultra-modern YZ250F also gets fuel injection, all of the the larger Five MX 250s to take some action.Yes, EFI is large, but Yamaha applying the engine-layout technology of your 450 in to the 250 will be bombshell news here. Last 2010, you might recall,Toms Shoes Outlet, Yamaha stunned the MX world aided by the introduction of the company's 449cc engine with intake in-front and exhaust in back.

The fuel-injection system contains a 44mm throttle body fed utilizing a high-pressure battery-less electric pump, as well as new underseat tank carries 2.0 gallons of gas, a rise of 0.4 gal. as compared to the previous model.Chassis upgrades to the motorcycle engine covers 2014 Yamaha YZ250F have an all-new bilateral-beam frame, while KYB’s air-oil separated, speed-sensitive fork and shock the exact same make were updated. Such as the new 450, the YZ250 comes with a new air-filter design that creates accessibility handle grips foam element quite easy, while its forward location keeps it farther away from the dust and roost kicked up through the rear tire.The Yamaha YZ250F arrives at dealers in October, in a choice Yamaha Blue/white or white/red.
