:busted::thumbsup::banana:

Just because its new its nicer? The 2010 YZ250F looks pretty much the same.

The over use of smilies detracts from your message, but nice effort.

Its very similar to the 250f but there are some slight differences.

:busted: Look at the price:

$8,090 (White/Red) Available from September 2009

$7,990 (Team Yamaha Blue/White) Available from September 2009

Nice to see something truely new and different instead of mildly re-worked frame or head design or new suspension settings. Can't wait to read the tests on it.

Seven pounds heavier than the 2009. I guess a more compact weight though.

They even increased the travel a little.

One fairly significant change I noticed is that they went to a 4-valve layout. The 250F keeps the 5-valve. I wonder if this has to do with the new engine position and intake/exhaust redirection, the addition of fuel injection or if there is something else going on.

Awesome..love to see multiple changes..looks like the yamaha engineers have been busy this last year.

Very Nice. Can't wait to see this tech on the WR's.

Yamaha is THE company to bring new tech to bikes of all the big 4...hands down.

+1, this is radical, so many new things in one model change, and new concepts:applause: :busted:

Well they pioneered the new age 4 stroke, they may as well pioneer the next generation 4 stroke too

Wonder how much a aftermarket exhaust is going to be :busted:

Hopefully, this won't be a Japanese Canondale.

The frame rails look rather wide. I wonder if riders with knee braces will complain.

Also, I wonder if that heating coil exhaust will cook the shock while running slow trails off-road.

I love the new innovations. Makes sense to have the intake in the front. Very cool.

so those 'fake' CAD drawing floating around turned out to be true?

Yup!!

Should be a lot of TT members eating crow over this one.

Looks like it could potentially damage/crack/break piston skirts with the offset crankshaft.

Not immediately, but over time of course. Not a problem with regular maintenance.
