If I close the throttle completely at low speed, I'd think the bike just slows down smoothly.

Hikari

Not on an automatic—engine power cuts out completely and you can actually lose stability.

Momoka

Wait, so chopping the throttle can make me wobble?

Hikari

Exactly. Keep a little throttle on at low speeds to stay stable and in control.
