In these times of crisis that the evolutions of the most cutting-edge models of all disciplines are running, they are more widely spaced in time, but in the case of machines as evolved as the Yamaha YZ-F 450 you only need to update with small tweaks the existing model so that the brand's spearhead continues to be a highly effective model. Even more so when with the 2010 model they revolutionized the scheme of dirt bikes known to all by turning the engine by placing the filter box and the intake at the front and the exhaust at the back, managing to centralize the masses and thus trigger its handling and stability..

For this year Yamaha has decorated the YZ450F with new colors and graphics keeping the two options with a white and blue base. But in addition to these aesthetic changes they have retouched some mechanical parts. Let's take a look after the jump.

Yamaha YZ450F 2013: Technology brushstrokes

YZ450F.2

The piston It is new, lighter, the gas flow, both intake and exhaust, has been revised to make the engine run looser and rotate more naturally, new injection system battery-free more efficient, software capabilities to modify injection settings with the attachment have also been adjusted GYTR® Power Tuner.

Remember that this Yamaha It is a motorcycle of cutting edge technology with its intake and exhaust structure in reverse of the conventional, a body of electronic injection without battery of last batch in front of the engine block, fuel tank under the seat and various modified mechanical parts, all designed so that the center of gravity of the bike is at the most neutral point and moves faster than Rafa Nadal at Roland Garros. I would not see justification for making more mechanical changes than those strictly necessary to keep the flame alive, and of course, with this machine you can cause real natural disasters with good hands that handle it.

Yamaha YZ450F 2013: Cycle part tested without fanfare

YZ450F 2013

As for the cycle part, wider footpegs and something that seems to me the most successful, keep relying on a conventional spring fork instead of relying on the KYB air spring (PSF) that are becoming so fashionable and already mounted on Honda and Kawasaki. Possibly the future goes in that direction and it would be obtuse to deny it, but if for twenty years the conventional inverted forks with helical spring have demonstrated a more than solvent operation, it is a step perhaps too big for a set that does not need to be redesigned again.

Personally, I am not a friend of so many "gadgets", I prefer that these machines to get dirty are fast because of their simplicity, but until it falls into my hands and I see that their operation really justifies what they are worth, they will have to be given a vote of confidence.
