Castor Wheels VS Motorcycle Wheels- Why Choose One Over the Other?
First, let’s speak about what a castor wheel is. It is a wheel that is used to move heavy objects on ground surfaces. They are also known as a caster, swivel caster or mobile caster.
Motorcycle wheels are round and have spokes. Castor wheels have a flat surface and no spokes which means they can be turned at any angle to move the object in any direction.
Castor wheels balance the weight of an object so it can be moved easily whereas motorcycle wheels have to deal with the weight of an object from all directions which makes them heavier than castor wheels because they have spokes that need to support the load from all sides.
