Design

You are looking at a mutlipart ring, resembling an air cooled motorcycle engine.
Shown are cooling fins, ignition plug, two push rods (for valve actuation) as well as conections for air and exhaust gas pipes. The elegant hex key bolts, which are sunken into the cylinder head cover, create a unique ring with authentic engine design.

In order to limit the rings height without limiting the theme, cooling fins are introduced into the band section of the ring. This leads to a relatively flat and still practical ring that nonetheless creates the illusion of a complete air cooled cylinder.


Multi Part

Main characteristic is the assembly of two parts. Attached to the engine block with raw casting surface finish is a polished cylinder head cover, creating an authentic model.

The ring is always made of solid sterling silber.

The polished cover is available in the materials brass, bronze, silver, 14 karat normal, rose and white gold, as well as 18 karat gold and brass plated.

M 1.6 nuts are sunken into the upper part of the ring band, right underneath the engine block model.

M 1.6 x 6 steel bolts reach through the head cover of the machine and are secured with lock tite in the nuts.

Thereby no precious metal parts are touched by glue. Only the bolting is secured in the typical engineering fashion.
