We were in Wyoming stopped and looking at the mountains and three bikes passed by in neutral the engine off coasting quietly. So I tried it and coasted at least 3 miles maybe more, it was ok, just something different.
Could this hurt anything like a bearing not gett enough oil?
From a riders safety point I advise against coasting. You never know when you'll need to have an emergency maneuver that may include accelerating. Coasting removes that ability as well as engine braking.
Coasting in neutral takes away 50% of one of the two things you can control.
Is it as dangerous as pimp slapping a 1%er and calling him a *****? Probably not. But as stupid as people are these days I never willingly give up an advantage when riding on two wheels.
