The Saronno Mechanics Shop was created in 1987 to integrate the work carried out at ORAL mechanics. Thanks to the experience already accrued at that time by ORAL mechanics, OMESA began its course specialising in building and manufacturing spool engines and camshafts. Over the years OMESA has acquired a role of particular importance in the world of competition thanks to some important clients, among which we note Mercedes, Toyota and Lamborghini.

This success is also due to the fact that the organisation can count on a rolling stock specialised in the production of these items. In fact, it is noted that items such as spool engines require, as opposed to other engines, specific machinery dedicated exclusively to their production.

The work carried out by these three organisations can be summarised with one simple concept: Oral is capable, today, to design every part of an engine, produce it, assemble it and finally bring it to the point of sale. This system has already been proven for quite some time thanks to the close cooperation of one of the most important German car companies in the racing world.
