Honda makes some nice bikes.  Their best bike is the CRF450.  It is the best 450 out there.  These bikes are usually red.  Travis Preston is probably the best rider Honda has.  Kevin Windham is probably the second best rider for team Honda.

Kawasaki by far has the best bikes.  They are a good KX450F and the Best KX250F.  The best rider today James “Bubba” Stewart rides for team Kawasaki.  Or also known has Team Green.  Since most of their bikes are green. 

Yamaha are not as good bikes.  They are my least favorite kinds of dirt bikes.  Yamaha bikes are usually blue. But on 2007 they came out with a yellow and blue edition.  They have one of the best riders out there today in Chad Reed. 

KTM make some great bikes.  And they keep getting better.  They will probably pass up Kawasaki soon for the best bikes.  These bikes are orange and black.  Their 2008 models are the most improved bikes. 

Suzuki are my favorite brand bikes. I have two of them. They have two of the biggest names in the sport.  Ricky Carmichael who is the best Motocross racer ever.  They also have Travis Pastrana who is the best doing tricks on a bike ever.  Suzuki makes the best 125.  These bikes are usually yellow.  They will also just keep getting better.
