Engineering Team

OMI is an engineering team that since 1979 has been deeply engaged in a continuous activity of design, testing and development of engines, mainly aimed at the two-wheeler market

Our evolution

Until the end of 2010 Team OMI worked as the engine engineering division of CGM Electronics, a company among the first in Europe in the field of design and manufacture of OEM engine testing instruments for AVL-Graz. Since 2011 the Team has been working as a completely independent company with increased staff, design and testing tools, under the name of Eta Engine Technology.
