Does any one know ne thing about the 06 yfz? what size motor ive heard rumors of a 449 cc is this true?? ne thing else u guys know please post

i believe they are the same, a lot of bikes go by higher numbers, like the 400EX, its only 397

There are lots of rumors that it will be a true 450. But, who really cares. 10cc's is not going to be a noticable difference.

Yea 24v is right 10cc's is not going to make any diferrance,maybe a little but will not nittice.

is the 450 now like 439 or something?

yup.

The next quad to watch out for will be Suzuki addition to the 450 ranks.Damm drag bikes are fast!,just hope they don't steal from that side of the company.
