Not forgetting the great Sammy Miller.
I don't know Sammy's actual full history but seem to remember him being classed as one of the greatest "allrounders" within motorcycle sport.

Ooops sorry Don, I hope that I have not highjacked your thread. :oops:

Sammy Miller, another great example of a cross-over rider.
A trials champion (or should I say THE trials champion) who comes in three places ahead of Mike Hailwood in the 1958 Ultra lightweight TT!!
Natural talent will out every time.
