2014 Yamaha YZ250F – Start looking Brand-new, fuel-injected engine does a 180.
If you’ve studied Yamaha’s family tree within the last few few years, perhaps you believe the YZ450F and YZ250F motocrossers aren’t even related. Sure, they look somewhat alike with regard to their similar graphics and color schemes, but below the surface their DNA was clearly quite different.But is not now. The 2014 Yamaha YZ250F has developed into a a bit smaller version from the radical bigger, replete having a rearward-leaning cylinder that features the intake staring at the monitor and exhaust with the spine. What’s more, the ultra-modern YZ250F also gets fuel injection,motorcycle helmets, all of the the best Five MX 250s to do this.Yes, EFI is very large, but Yamaha using the engine-layout technology of your 450 towards the 250 may be the bombshell news here. Assistance programs were 2010, perhaps you may recall, Yamaha stunned the MX world with the introduction of the company's 449cc engine with intake at the front end and exhaust at the spine. Although Yamaha wasn’t the first ones to make it happen ( clip on handlebars Cannondale, because of its MX400, was), the YZ450F was the very first bike from the mainstream manufacturer for getting this novel design.Front 3/4 left-side viewBesides mass centralization and a undisclosed bump in power, anoth sportbike mirrors er benefit to this engine is mostly a steep intake downdraft angle, that is definitely optimal for top-end power, says our Technical Editor Kevin Cameron. Internally, the fresh new YZ250F uses exactly the same bore and stroke dimensions (77.0 x 53.6mm) as before, however it is new twincam head has four titanium valves on five. Like for example the new Yamaha YZ450F, the exhaust in the 250 wraps to the engine from behind, optimizing mass centralization and helping Yamaha achieve the ideal header length. The fuel-injection system has a 44mm throttle body fed by the high-pressure battery-less electric pump, additionally, the new underseat tank carries 2.0 gallons of gas, a gain of 0.4 gal. if compared to the previous model.Chassis upgrades to the 2014 Yamaha YZ250F include an all-new bilateral-beam frame, while KYB’s air-oil separated, speed-sensitive fork and shock of the same make happen to have been updated. Such as new 450, the YZ250 contains a new air-f motorcycle rear stand ilter desi handle grips gn which causes access t ducati clutch covers o the froth element a lot easier, while its forward location keeps it farther away from the dust and roost kicked up through the rear tire.The Yamaha YZ250F finds dealers in October, in either Yamaha Blue/white or white/red. Price: $7490. Although that’s a rise of $200, the new YZ250F is mostly a a lot more modern machine, now a honest relative for the YZ450F.
