Following round three of the 2011 World Superbike Championship, at Assen, Carlos Checa and Max Biaggi are now first and second in the standings.

At 38 (Checa) and 39 (Biaggi) years old, the pair are among the most experienced on the WSBK grid. Both also spent much of the world championship careers in grand prix racing - and were team-mates at the Factory Yamaha 500cc/MotoGP Team from 1999-2002.

Ahead of what looks like being a 2011 championship battle between the pair, the below table shows how they compared as team-mates.

At Yamaha, Biaggi clearly had the upper hand over Checa on both the 500cc two-stroke (1999-2001) and 990cc four-stroke (2002).

In races that they both finished as team-mates, Checa beat Biaggi on twelve occasions.

However, so far in 2011, it is Carlos and Althea Ducati that hold a 43 point lead over Aprilia's reigning WSBK champion Biaggi.

Biaggi was a four-time world champion in 250cc grand prix racing, while Checa is yet to win a world title in any class. Will that change in 2011?

Checa v Biaggi: 1999-2002 Wins: Checa (0) - Biaggi (8) Podiums: Checa (12) - Biaggi (28) Poles: Checa (1) - Biaggi (17) Points (total): Checa (558) - Biaggi (798) Best championship position: Checa (5th) - Biaggi (2nd twice)
