Sirio 220 VL

The Gilera 220 Sirio was the next step up from the 175 cc, Gilera’s first "utilitarian" model produced in 1931 with the fiscal advantages the government offered to encourage mass motorisation. When the 175cc displacement stopped benefiting from these advantages, Gilera decided to produce the 220, which remained on the product catalogue until 1941. The 220 was modified from the 175cc, with changes in valve diameter and clutch size. It also made abundant use of roller bearings. Contrary to normal practice on higher displacement engines, the removable cover for valve adjustment was placed on the camshaft rather than the finning.
