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.

At the 13th annual 'A Day in the Dirt' I got a chance to talk with Sayaka "Teriyaki Sauce" Kaneshiro, WMX Pro #15
How was your racing today?
It was good, I thought we had a practice first, I went out and it was actually a race. I was just racing and riding around, I felt like ... WOW!

What did you think of the event overall?
It was to difficult racing for me, because I didn't ride my pace. I rode about 6th place, less than I wanted to. I got the same number as last year, I just tried to do my best.
