TUNING RACE – for professionals

For race use only. Not admitted in the area of the German StVZO! Product description
The new M1L cylinder kit moves up the evolution ladder with their already powerfully successful QUATTRINI cylinders. These well known cylinder kits are already icons of performance, features and quality. QUATTRINI has evolved once again, making the Kit the best of the best. 5 transfers and a massive reed valve induction feed the QUATTRINI cylinder, features like additional Boysen ports (secondary intakes direct to the transfers), and an extra large 4-petal reed vavle are simply part of the package. Not to forget the larger auxiliary outlets, a centered cylinder head, as well as Italian name brand quality piston with HQ 1mm piston ring. All QUATTRINI cylinders are of the highest quality workmanship and have an unrivaled finish. QUATTRINI means dependability on the hi tech racing level. Your crankcase must be modified, but will not need welding at the first tuning level. The QUATTRINI manifold is designed for Vespa V50/PV/ET3 models, if used in Vespa PK models, the frame opening will need additional modification. Exhaust stud distance is 57mm. Some race exhaust systems will need minimal enlargement.
Conclusion:
