YAMAHA YZ250F 250 (2011 - 2012) Description & History: The 2011 Yamaha YZ250F sports an outstanding throttle response, thanks to new crankshaft webs, new vibration-reducing counterbalancer, new connecting rod, and low-friction piston rings, as well as a new piston, piston pin, and clip assembly that’s over 8% lighter overall than before.
To take full advantage of these advancements, there’s also new CDI mapping and a bigger 39mm carb with freer breathing air cleaner cage. Added to the new frame and suspension refinements, this latest engine gives YZ250F amazing balance – a powerful, light-handling machine with performance that’s accessible to all levels of riders.
The YZ250F has specially-tuned forks and a sturdy yet lightweight frame, created with agility in mind, offering very good fast cornering. Foot pegs and handlebars are adjustable to fit multiple riders and offer them the movement freedom and the most comfortable stance.
