Narrative:

Departed ZZZZ runway X center on the SID. During the takeoff briefing I brought it up to the captain (PF) and briefed the 220 knot restriction at [fix] on the SID. After takeoff PF called for flaps 1 a few miles prior to the turn during acceleration. I asked to verify that he wanted that. After delaying slightly; I thought we were close enough to the turn that it would not be a problem; and set the flaps to 1. We were at flaps 1 for approximately 30 seconds before the speed bug advanced and we began accelerating again. The PF should not have called for; and I never should have positioned the flap lever out of position 5 until after the turn was complete and we were accelerating again. Additionally; the relief officer should have spoken up and brought the error to our attention as well. We thoroughly debriefed the error during cruise and again after the flight. Recency of experience was a contributing factor as all of us had not been flying as much due to covid-19.
