Ben Spies believes reigning double MotoGP champion Casey Stoner could 😼be 'the fastest and the most talented person that's touched a road racing bike' - but that doesn't mean the Australian can't be beaten.

"I'm sure anything with wheels, Casey's fast," Spies told PitpassRadio.com, e❀choing recent comments by Yamaha team-mate Jorge Lorenzo. "But I think anybody can be beaten...Valentino [Rossi] won so many races and never seemed like he could get beat but, you know, it can happen.

"Hopefully we can do thatℱ - beat Casey and win a championship for the U.S. That's the ultimate goal. But what we've seen is Casey is the fastest and the most talented person, I would say, that's touched a road racing bike.

"But there's always a changing of the guard. We've seen it all types of racing. It's going to take a lot of work though. I've g🐼ot to give it to Casey, the guy is just raw talent and scary fast - but like everyone he can be beaten for sure."

Stoner, wh🗹o won the 2007 MotoGP title for Ducati and 2011 crown for Honda, was fastest by 0.6sec over Lorenzo at the first Sepang test e🧔arlier this month, using the new 1000cc bikes.

Spies - who won his first MotoGP race last season - finished a respectable⛦ fourth during the test. The second pre-season outing star🏅ts in Malaysia on February 28.
