Top case carriers are special brackets that are used to attach top cases to specific points on the motorbike.
They are usually made of robust steel or aluminium and are attached to the luggage rack or luggage carrier. Topcase carriers are available in various designs, depending on the motorbike model and topcase size.
A good top case carrier should ensure secure attachment of the top case and provide sufficient stability on the motorbike to prevent it from slipping or wobbling while riding.
