Consider your motorcycle turns a little deeper.
Initially you have to START a turn with a force on the handlebars into the turn which initiates a bank/roll of the machine. The bank immediately and progressively causes turning instability as a result of its deliberate design and if left to itself would automatically tighten to a spin out. Once into a turn you have to use an opposite handlebar force to counter the instability. Motorcycle riders seem to prefer this type feel.
I wouldn't care to approve such instability for an aircraft!!
