This test trumps the racerx test by far. But as with all tests, take them for what they are, a group of rider's findings, not necessarily always universal. http://www.dirtrider.com/tests/motocross/141_0807_web_test_2009_yamaha_yz450f/index.html Edit: I just read the whole test, it appears this is an actual test VS the TWMX and Racerx "press tests", Dirt Rider actually has 10 hours on the bike, plus they used different test riders with varying ability and allowed them to share their opinions. Basically they put on of their "printed tests" on the web, it seems like something new they have started doing, and its pretty decent in my opinion. One cool thing they did, was allow their dirt rider forum members to ask questions about the bike, they then posted the questions along with the answers on the last page of the test, pretty good and you have to give them credit for thinking outside the box since noone else has done this as yet. I know i have been critical of magazine tests like the ones we have seen online, but this one actually has some substance to it.
