The final session in each category saw Takaaki Nakagami and Luis Salom quickest again in Qatar.
The Moto2 and Moto3 classes finished their preparations before qualifying for the Grand Prix of Qatar with the final practice session on Friday evening, and the leading rider from the previous day in each category remained the leader.
In the most unusual of circumstances given the location of the Losail International Circuit both sessions were affected by rain showers, and that meant that very few riders improved on their lap times from the day before.
In Moto2, Takaaki Nakagami was quickest in FP3, as he had been the day before, and the faces at the top of the timesheet on Friday were familiar. Pol Espargaró, Scott Redding and Esteve Rabat were all up there, with all signs pointing to a great season-opener on Sunday.
Sandro Cortese continues to improve at a rapid rate in his first GP as a Moto2 rider. Last year's Moto3 World Champion was 11th in a field of experienced riders, while fellow rookie Danny Kent was 18th in the order on Friday.

In the Moto3 category Luis Salom topped the final practice before qualifying, but like in Moto2 the session was slower than Thursday's FP2 as the Moto3 riders were also affected by light rain showers too.
In the session Salom was followed by Álex Rins, Jonas Folger, Jack Miller and Efrén Vázquez in the top five, with Red Bull KTM Ajo's Zulfahmi Khairuddin one of just two riders who managed to improve on their time from the previous day as he closed the session 18th.
It meant the times from FP2 stood firm as the reference point across all three practice sessions, with qualifying due on Saturday evening. Along with Salom and Folger, another title favourite looking for a good grid spot will be Maverick Viñales.
The Spaniard is riding through the pain barrier after losing the tip of the ring finger on his right hand in a testing crash at Jerez last month.
