Steering lock left (original)

The added value of a steering strap for a moped (Wallaroo) is:

Extra strength: the handlebars cannot twist or wobble while riding.

Better control: especially noticeable at higher speeds, on curves, or on poor road surfaces.

Safer: less chance of the handlebars coming loose or slipping.

Sleek appearance: often used on custom or sporty mopeds for a cleaner look.
