Avanti Cylinder Head (70mm) for cast iron and alloy kits

Avanti Heads are now available for all engines not just the TT3

After various tests done by others, including a Rapido kit with one of our heads prepared by Darrell Taylor. AF Rayspeed have been supplying Avanti Heads for their RB kits after intensive tests we are now ready to supply heads for any series 1, 2 or 3 Lambretta’s.

Compression ratio is 10:1 as standard. As with all Avanti heads the diameter is 180mm (a standard Lambretta head is 140mm).  This will need a Head Cowl to fit priced separately.
