I was asked a question on Twitter last week by @robostarred, who said this: "Is MotoGP a credible sport now? Given [there are] only 3 manufacturers left, and road bikes [are] now being used."
It is an interesting and a contentious question that is being asked as much inside the paddock - from riders to journalists - as it is among fans, as premier-class grand prix motorcycle racing moves away from 100% prototype racing in 2012.
However, the first thing to point out is that the Claiming Rule Team (CRT) bikes that are being prepared in readiness for next season - the ones that will fill the grid in the not-too-distant future - are certainly not road bikes.
They remain largely prototypes, albeit currently with tuned Superbike engines, and although they have made a predictably slow start to life in testing with inexperienced riders on board, they will soon be lapping quicker than any production model at most circuits.
