I'm with Nate, I thought most other national championships used WSBK rules. I thought for sure that the Brit SBK does.
The sad truth probably is ... you get 50,000 people to a Brit SBK race...and 5,000 at a US SBK race.
Shouldn't Ben Spies be a shinning example of the fact that the US SBK series produces world class riders? And the "unlimited funding" is bullshiit, no one in any series these days has unlimited funding.
DMG is just manipulating things in an attempt to garner the most profits they can.... problem is they don't seem to understand motorcycle racing or it's fans.
Another sad truth is that about 1 in 1000 people in the US give a crap about motorcycle racing, and out of that number...about 1 in 20 give a crap about the rules, or how close the bikes are to stock, or not. The squids buying 80% of the sport bikes don't follow racing much less the technical rule discussions.
