I keep thinking it would be a blast to have mixed racing twice a year to determine the champion racer(s) of the year by requiring the TT and MotoGP racers to race each other. One race would be at the Isle and the other would be at a Moto GP track. It would be like the golf majors that make the players from the Euro tour, asian tour and PGA to play each other, or the Major league baseball world series where the NL and AL play each other... I wonder if the salary charts would get adjusted as the sponsors realign. That said, not sure how many races the TT racers do vs the ~20 motogp races. Some rules would have to be adjusted to equalize the bikes?
Haha. Maybe motocycle racing's popularity could go sky high.
