MotoGP title contenders Jorge Lorenzo and Dani Pedrosa were among twelve riders to sit out this morning's opening practice session for the San Marino MotoGP.
Only nine riders posted a lap time due to cold and damp conditions at the Misano circuit, the best of which - a 1m 43.178s by Danilo Petrucci, set on soft slicks in the closing minutes - was ten seconds from dry lap record pace.
Petrucci and his Ioda team are making their debut with a Suter-BMW this weekend.
Behind Petrucci were fellow CRT riders Michele Pirro (Gresini), James Ellison (PBM) and David Salom, who is making his MotoGP debut with the Avintia team this weekend.
The only manufacturer riders to record a lap, early in the session, were Americans Ben Spies (Yamaha) and Nicky Hayden (Ducati). Hayden is making his comeback from injury.
Second practice will take place this afternoon.
