Alex de Angelis returned to a MotoGP
machine for the first time since 2010 during a private test at Italy's Vairano di Vidigulfo circuit.
But the Sammarinese wasn't riding the kind of manufacturer MotoGP
bikes he raced full-time for Gresini Honda in 2008-2009 (including a podium at Indianapolis) then as a substitute for Interwetten Honda during three rounds in 2010.
Instead de Angelis, who rides for Forward Racing in Moto2, made his CRT and 1000cc debut riding the team's Suter-BMW MotoGP
machine, being raced by Colin Edwards
With Edwards overseas, de Angelis' main task was to try 'a new version of the electronic system' although bad weather meant they couldn't complete the full testing programme.
"I am very happy to have been considered by the team, Suter and BMW to participate in this test to develop the CRT bike,” said de Angelis.
"The test has been shortened due to the bad weather conditions, and we have not been able to do many kilometres, but nevertheless it has been very exciting to ride a 1000cc bike.
"We have worked on the development of the electronics of the bike, which we do not do in Moto2.
"I hope I have been able to provide the right feedback to the team, Suter and BMW, in order for them to develop the bike in the right direction.
"I would like to thank the team for this opportunity. I remain at their disposal to collaborate in future tests."
Edwards crossed the line twelfth and top CRT rider in the opening round at Qatar. de Angelis, who also uses a Suter chassis, failed to finish in the season-opening Moto2 event.
According to Speedweek.de
, BMW is developing a factory MotoGP
project which could be seen on track later this year, followed by wild-card entries in 2013 and a full campaign in 2014.
