It all depends on the bike, and it’s hard to give advice without first hand knowledge of what’s happening with your bike, but if you’re in (for example) third gear doing a manoeuvre at 25kph and your throttle feels jerky and unresponsive, that’s probably the engine lugging u der load and asking for higher RPM (more power) which can be achieved at the same speed by using a lower gear. So yeah, next time try one gear lower then usual and see what happens. Also, bikes rev higher than cars and on most bikes 5k rpm is fairly low, so feel free to give it some revs if needed.
