2008 Yamaha YZ450F Motocross Bike reviews

I read the previous review on the bike and felt the need to comment. I'm the original owner of an '08 YZ450F and would buy 20 more if I could. The bike has had very little issues outside of normal maintenance. In Arizona we ride year round with winter temps averaging in the 60's to the summer blazing heat of 110. With the extreme conditions the bike has held together great. The only issue that Yamaha could change on their bikes is the plastic sleeve for the compression valves in the forks. Over time they crack and affect the performance. You cannot buy just the sleeve, you have to buy the whole assembly at $250+ per side! I also have several friends that ride the same bike and they have very few issues with theirs as well.

Lots of wheelie popping power. Great for the track and trails. I would recommend this bike.

This is the first 450 that I have owned. I have ridden/raced 250 2-strokes for the last 6 years and I was starting to get discouraged running against the 450s. First off with the new bike the suspension just blew me away. It is incredible. I have never ridden anything close to this. All my other bikes were revalved and they don't even touch the performance of the stock stuff on the new Yamaha. The motor has tons of power, but the delivery is smooth. For me this is great. I race right to the checkered flag and I want more. Before I would be so tired that my tongue was dragging before the white flag flew. Reliability and quality are great also. Junk the stock chain immediately and the sprockets last really well. Bars are good stuff stock. The front brake lever is tough to get aftermarket right now and it is a $50 lever through Yamaha. ASV is the only replacement I know of. I have them on mine already and I love them. I strongly recommend this bike to anyone. I think that it is great all around.
