Lighter, faster, quicker the ultimate YZ
The 2014 model is a completely new beast. A completely redesigned fuel injected motor and flighty racing machine to decimate tracks across the globe.
After several careful years in making the forward-positioned straight intake, rearward slanted cylinder and 'snaking' exhaust system has arrived.
Housing the growling engine developed through Grand Prix is a brand new chassis helping to drop weight even further and centralise the riding sensation for a powerful off-road experience. This is the ultimate.
Without a doubt the 2014 YZ250F is Yamaha’s most responsive, useable and thrilling 250cc machine to materialise from the assembly lines in Iwata.
New fuel injected engine
For the first time the YZ250F makes use of fuel injection for excellent power characteristics, better response and more grunt. It adopts the same functional and integrated design concept as the YZ450F. Mapping is fully adjustable and power output is deepened by new snaking exhaust system, carburized cranks, two ring piston design and more.
Rear-slanted, forward thinking
The forward-positioned straight intake ensures excellent efficiency while the rearward slant of the engine is set at the optimum angle with regard to the frame, engine size and mass balance. The full extent of the ECU can be exploited through the optional MX Power Tuner to customise set-up for personal preference and terrain conditions.
Centralisation and weight saving
The 2014 exhaust system means the silencer can be reformed and reduced, permitting a shorter sub-frame; just one of several factors in the improved mass centralisation of the motorcycle. A repositioned fuel tank (now 7.5l) slimming the bike even more and allowing easy access to the air filter is part of this package.
Lower and lithe chassis
The YZ250F is renowned for its potential in turns and now benefits from a newly designed hydro-formed bilateral beam frame constructed from ten different types of forged, cast and extruded aluminium parts. Achieving precision and control the chassis blends new levels of rigidity, balance and shock absorbing element for 'ultimate' feedback and fun.
Gearing up
An improved clutch feel and a redesign of gear-shift components have achieved a smoother, surer shifting sensation. The effect is to reduce driveforce loss during gear changes.
Feisty new image
The edgy and athletic form of the YZ250F forges a bike for 2014 and beyond. The ultimate YZ models are styled for one purpose; dedicated competition. New plastics, air scoop, rear mudguard and aesthetics are complimented by ‘in mold’ graphics applied to the bodywork for a more resistant surface; a technique used for the first time on a Yamaha motorcycle.
