MotoGP rider Toni Elias made his World Superbike debut for BMW Italia during the first day of testing at Misano on Tuesday.
The reigning Moto2 world champion and former MotoGP race winner has struggled throughout the 2011 season with LCR Honda, and is considering his options for 2012.
The Spaniard was eleventh fastest out of 13 riders on Tuesday, during which he suffered one fall without harm.
Toni's best lap time was 2.1sec behind former MotoGP team-mate Marco Melandri (Yamaha) but only 1.3sec from the leading BMW of Ayrton Badovini.
Elias was faster than fellow MotoGP race winners Chris Vermeulen (Kawasaki) and Makoto Tamada (Honda).
BMW Italia is a satellite team - the factory BMW squad of Leon Haslam and Troy Corser were not present.
Testing concludes today (Wednesday) after which Elias will head for this weekend's Aragon MotoGP round.
Elias is presently 14th in the world championship with a best finish of ninth, in the wet at Jerez.
