That's an interesting read, I've heard a few people say that the top MotoGP guys would walk it at the TT and I've also heard a few say they'd be no good at it, I personally think the answer lies somewhere in the middle, there's no question that a top GP rider is talented enough to win a TT race as they're the fastest riders in the world on the fastest/hardest bikes to ride. However you can't ride the TT or any road race for that matter in the way they ride around Phillip Island or Mugello, so in effect you'd need them to ride within themselves I think.
