Cylinder Head SERIE PRO 'Il Naso' for Vespa 125 V1-15/V30 Naso' for Vespa 125 V1-15/V30-33/VU/ACMA/Hoffmann A/B Ø 56,5 mm, 1:8, aluminium, CNCmachined, ROAD-TUNING, for everyday use& reliable This is a special 'Il Naso' cylinder head, produced by Nagy Blechroller, suitable for fitting to all wideframe motors fitted with a deflector piston system. Due to the re-profiled combustion area of this cylinder head and its higher compression ratio of 1:8 it can improve the acceleration and increase the top speed produced by the motor. This CNC milled cylinder head can be 'Plug & Play' mounted to the original cylinder without adjusting the jetting of the carburettor! SIP - TIP : We recommend that this cylinder head be combined with a POLINI carburettor kit to release its potential. A spark-plug equivalent to a NGK B7HS is also necessary!
