Spaniard Marc Marquez dominated the final day of testing at Phillip Island in Australia on Friday.
The former world champion took advantage of the dry morning session to post a 1m29.158, just over a tenth of a second quicker than Suzuki rider Maverick Vinales.
With the rain coming down around midday, Marquez was also one of eleven different riders to fall in a total of 13 crashes around the wet track. Most riders went off around the Honda hairpin.
Danilo Petrucci went off on the fast turn eight with an hour of testing to go, bringing out the red flags. The Italian suffered a fractured right hand.
World champion Jorge Lorenzo would settle for ninth, while Yamaha teammate Valentino Rossi was fifth fastest, nearly three tenths off the pace.
