But speaking of Spies, I was wondering how many riders have won races in WSBK and grand prix motorcycle racing. I've got Vermin, Checa, Bayliss, and Biaggi off the top of my head. I think Vermeulen might actually be the only person to win a MotoGP, WSBK and WSS race. Anyone else?
Doohan and Magee won as Superbike wildcards. Kocinski, Lucchinelli and Chili were regulars in both series, winning multiple Superbike races, though Chili's only GP win was in slightly dodgy circumstances involving a works rider boycott and some sarcastic clapping from Eddie Lawson. More recently you've got Regis Laconi and Garry McCoy. The latter of whom had a chance to do the 500/MotoGP-WSS-WSBK three-peat, but the Triumph 675 wasn't strong enough. Simon Crafar won a famous Grand Prix at Donington Park, but he didn't ever win a WSBK race, though he most certainly should've.
On a related note, Vito Guareschi, Maio Meregalli and Wilco Zeelenberg have won WSS races and MotoGP races as team managers. Which probably says it all about the status of WSS as a route to Grands Prix, especially in the early years. Of the three WSS 'graduates' to GP that I can think of, Vermuelen, Xaus and Toseland, none of them lasted particularly long, and all favoured a quick return to Superbikes rather than hanging around trying to bum a ride somewhere in the paddock. So Crutchlow and Rea had best be careful.

Now, if we could include national Superbike championships and victories in this calculation, the list would be a bit longer and a lot more illustrious. The Australian and AMA Superbike championships significantly pre-date the World championship anyway, and at times have certainly been more prestigious.
