There are two classes in AMA professional motocross: the 250cc Lites class, and the "Motocross" class, which can run engine sizes from 251cc to 500cc. Most riders race 450cc machines in Motocross, with KTM also having a 350cc machine.

Last year I won the TORC Pro 2 Off-Road Truck racing championship. This year I'm moving to the Pro 4 class.
What's the difference between Pro 2 and Pro 4? Pro 2 is two wheel drive. Pro 4 is four wheel drive.
With Pro 4 you can drive more aggressively - you can get on the gas more, because you have much more traction with all four wheels.
Also in 2011, I'm with a new team - Menzies. Plus I have help from Dodge, and Red Bull.
In this video below, this is one of the first times I started testing for 2011. It's a track at Glen Helen Raceway! (Home of the US MX GP)
