I was PM for this leg back to ZZZ1. We were cleared for takeoff on Runway XX; lined up on the runway; and I gave the controls to the FO. He set the thrust levers to CLIMB and called 'set thrust.' I checked the stack and verified the N1 indications were in the carats and stated 'thrust set.' I failed to push the thrust levers into the TOGA detent and neither of us noticed. The remainder of the takeoff was uneventful. When performing the after takeoff flow I realized that the thrust levers were already in the climb detent.This was my first trip on the type aircraft since being checked out earlier this month. I have exclusively flown the different version of aircraft type for the last X months and have not become accustomed to setting the thrust in Aircraft X compared to the previous type aircraft. I was a type Y aircraft FO before upgrading into this type aircraft so my time in all three variants is very limited. I had only done three legs in this type aircraft as PM before today; the rest of the legs being as PF to practice landings. My habit of pushing the thrust levers past the climb detent and into the TOGA detent has not been set yet; as for the majority of my legs I was only setting them to CLIMB; then the PM pushing them up to TOGA before I put my hand back.I need to fly this type aircraft more often to become/stay proficient. It also would have been better to do OE in this type of aircraft sooner to start those habits earlier and not get into such a groove in only the other type aircraft. I guarantee I will never make the same mistake again as it was quite a shock when I realized what I had/had not done.
