The Omicron chassis was available in three versions; the C and L, both with two-axles, and a three-axles option. The Omicron C had an 8300mm wheelbase, and the Omicron L had a longer wheelbase of 9530mm or 9850mm. Urban bus routes such as Rome and Tivoli used two-door bodies coach-built by Macchi and Carminati.
