I looked through the results and Yamaha came out on top again this year in Championships.
Yamaha - 11
Honda - 7
Kawasaki - 5
KTM - 5
Suzuki - 5
Cobra - 3
The thing that amazed me, is a lot of the Yamaha championships were on the YZ 450, the bike everyone bashes, and says it not a good bike. some of the most competitive classes went to Yamaha.
Honda surprisingly had two championships in the Mini Sr class, and their 85 by no means is at the top of the list as good bikes in the 85 class.
Suzuki dominated the super mini class.
Kaw got most of their championships thanks to some VET riders.
KTM and cobra, all came in the pee wee and 65 classes.
