No. I'm pretty sure the 2012 250 SX isn't even homologated. And even if it was it wouldn't happen. I like 2 strokes too, but it's over people.
Cairoli was to have ridden an SX250 last year but skipped the last GP when his mother passed away, Roczen did ride the 125 though. Don't you guys think they were on win bonuses from KTM too?
I'd get a kick seeing Dungey race a smoker but as you say, homologtion rules stateside obvously stand in the way.
Guess there are different factors involved, there are high profile 2 stroke championships in europe and sales of new smokers seem to be on the rise again for clubmen over here, so i guess it was fun for Stefan and Pit to send those two out last year on 2 strokes at the final round whilst having a unique oppurtunity to market their 2 strokes.
As aside to homologation issues, doesn't seem much incentive in the states for DeCoster to follow suit?
