The opening day of the San Marino MotoGP has ended with only 13 of the 21 riders registering a lap time after two cold and damp practice sessions at Misano.
Nine riders, seven of them in the privateer CRT class, had completed a lap in the morning session - and conditions were almost identical for the start of the afternoon 45-minutes.
The CRT riders that took to the track early in FP2 were confident enough to run slicks, while the initial prototype appearances - by Andrea Dovizioso
(Tech 3 Yamaha) and Alvaro Bautista (Gresini Honda) - were with wet tyres.
World Superbike star Jonathan Rea, making his MotoGP debut in place of the injured Casey Stoner
at Repsol Honda, then rode his first lap of a grand prix session on soft slicks after five minutes.
The 25-year-old Ulsterman, who has had three days of testing prior to this weekend, then briefly moved to the top of the pile after ten minutes.
But lap times were still over ten seconds from full dry pace and the frontrunners showed no intention of emerging from the pits - especially when spots of rain began to fall once again.
An accident shortly after for Avintia's Yonny Hernandez confirmed the dangers, although a further deterioration in the weather spurred a few more riders into action with wet tyres in the final ten minutes.
Ultimately only eleven riders were credited with a lap time this afternoon, the best of which was a 1m 42.030s by Cardion AB Ducati's Karel Abraham.
Abraham, who is considering CRT options to remain in MotoGP next year, was the only rider to beat the 1m 43.178s by Danilo Petrucci in the morning session. Petrucci and his Ioda team are making their BMW-Suter debut this weekend.
