aluminium CNC 70 mm TUNING RACE – for professionals This product fits on almost all products Product description A CNC machined cylinder head for Simonini cylinders. The Simonini Mini 2 Evo cylinder was actually conceived for motors in ultra-light aircraft. Due to its compactness, abundance of potential power while also being air-cooled these cylinders are also readily adapted for use on vintage Vespa or Lambretta scooter motors. In order to combine the two cylinders, the cooling fins are first machined down by many tuners. MMW have a compatible CNC machined cylinder head available that fits beneath the original cylinder cowling without modification. The spark plug mounting is off-centre and matches the original Lambretta layout. Conclusion: The ideal complement to the Simonini Mini 2 Evo cylinder and the MMW ‘Killer Case’.
