Except for starting the bike and the rare pull over to adjust a visor or something, my bike is never both running and in neutral.
Stopping at lights, I cycle through the gears, sometimes providing a moment of engine braking in each gear, sometimes just keeping the clutch in and dropping down gears as I pass through what I estimate to be the right speed. Even when coasting down, I very much like to have the bike sliding through a gear that will allow me to power forward at all times.
Of course I have had a very few (thankfully) panic stops where it’s full brake and I come to a stop in 5th gear. But I quickly kick down to 1st in case folks start piling up and I need to move (I also try to end panic traffic stops in as safe a place as possible, typically off to the side of a lane or splitting lanes (legal in Cali) and a couple cars into the backup.
