Coasting in neutral is not the best thing to do.
It makes stopping harder, causes excess heat that can glaze the friction surfaces, to the point it could be unsafe.

I down shift and use the engine to help slow down the vehicle.
No matter what vehicle. My bike, a car, or a truck of any size.
Especially on heavier vehicles.

Just don't red-line it when downshifting.
That can hurt the motor.
