Work in Progress: 1976 Laverda 750 SFC Elettronica Custom Replica

Our friend Thierry entrusted us his 1976 Laverda 750 SF for a SFC replica project. The Laverda 750 SFC is probably one of the most beautiful racing machines of the seventies. Extremely rare (only 549 produced between 1971 and 1977) and, in the case you find one original, they are generally also extremely expensive.

During the yeas various evolutions of the SFC were built. The last 34 of 549 were assembled between 1976 and beginning of 1977. They had the same Bosch electronic ignition as the previous model, the 1975 750 SFC “Elettronica”, differing mainly by their 5 spokes alloy wheels instead of the classic Borrani wired wheels. This is the particular model that we decided to build for Thierry’s SFC custom replica project.

Laverda 750 SFC Elettronica project progress: connecting rods are squared together on a special tool in order to have the same weight and be perfectly in line.

Laverda 750 SFC Elettronica project progress: crankshaft parts. Laverda crankshaft are composite and "Hirth" coupled

Thierry's Laverda 750 SFC project progress: Angelo measuring the timing of the C5 camshaft.
Moto Officina custom camshafts are another “detail” that will make the difference. For Thierry’s Laverda we have chosen our custom C5 where the timing of the woodruff key cut have been moved of 6 degrees for a better torque range instead of the typical C5 timing that favors high revs use.
