BGM top hats are manufactured by a supplier for the Japanese motorcycle industry in an excellent quality. The dimensions are exactly the same as the old original Innocenti ones. Therefore a perfect fit is guaranteed.

The abutments are needed to give the outer casing of the train on the frame or engine block a stop.
They are simply inserted into the appropriate hole.
Used, for example, on almost all Lambretta vehicles.
