Yep, that’s Kevin Windham’s CRF450 on the cover of the May issue of MXA. Kevin wanted us to test it and we wanted to test it?the rest was easy thanks to Geico Honda crew chief Kristian Kibby.

Testing works bikes is always interesting, because as much as we like the bikes of superstars, sometimes they are unridable by mere mortals. Not so with K-Dub’s CRF450. He made some good choices.

The MXA wrecking crew is immensely interested in how things work. When Yamaha came out with its infamous ice cream cone muffler, we wanted to look inside. Yamaha didn’t want us to see what was in there, but when we broke out the hacksaw they knew we were serious. In this story we cut 16 things in half to see what’s happening in there.

Team Yamaha may be ancient history, but you can still buy the exact same parts that Yamaha’s support teams are racing with. We test a GYTR-equipped YZ450F that topped 60 horsepower.

If you were to rate the 2011 motocross bikes on a five-star system, which bikes would you give five stars to? We don’t know your system, but we rate every bike in this single issue.

Did you know that the crank on your trusty, but rusty, motocross bike is offset to one side? Do you know why it is offset? Do you know how far it is offset? Do you think someone else would ever tell you the answers to these question? MXA wants you to know more about the sport than James Stewart’s favorite color.

It was only natural that the MXA gang would want to test the Troy Lee Designs’ CRF250 of Dodger Stadium 250 West winner Cole Seely?after all, Cole was an MXA guy before he became a Supercross winner.

Every month, MXA tracks down three people who are living the dream. They aren’t always riders, but they are all important cogs in the sport of motocross. This month, we profile Dunlop’s Marshall Plumb, BTO’s Dan Truman and freestyler Matt Rebeaud
