English scooter tuning at it's best! Paul Melici has the ultimate weapon with the PM40 Evolution. Not only the high quality, the perfect fit and classy design show that the PM is in the highest levels of small frame tuning; performance is right up there as well.
Designed for absolute top performance, the PM unfolds it's power especially in the upper rpm ranges with a monster sound. The system is a mover and is not for those who want to keep both wheels on the ground. The nice thing about the PM40 Evolution: like all powerful systems, it works best with modified cylinders, yet has been developed to get the best out of every set up. Performance development is smooth over a relative wide range. The unpainted variation should be painted with exhaust paint.
When installed in Vespa 50 Special Elestart/125 PV/ET3, the side compartment, and, on all PK models, the side sheet panel must be modified.
Conclusion: One of the strongest performance systems for small frame with a wide range of usage. The English alternative to Hammer Zombie, Franz and Co. Ideal for modified 133er Polini cylinders.
Racing exhaust / made of steel / aluminum silencer / Left hand curly
Steel, unpainted or chromed, silencers in aluminum silver colored, further silencers available as accessories.

SIP-TIP: Adjust main jets and new spark plugs are a must. Racing shaft with 51/54 mm stroke, racing cylinder such as QUATTRINI, POLINI, MALOSSI, PARMAKIT, electronic ignition such as VESPATRONIC or PARMAKIT, 24-34 mm carburetor recommended. A longer primary with DRT gears offer additional optimal variations.
