Regrettably the production of spare parts for the Vespa PK Automatica models has been sadly neglected by PIAGGIO in recent years. To prevent these scooters from completely vanishing from our streets and rallies we have decided to have some of the necessary parts reproduced.
The original cylinder head suitable for the PK 50/S/XL N Automatica / XL Plurimatica models has been out of production for a number of years. Due to our lack of success in persuading the original manufacturer to re-continue production, we are having the cylinder head produced from scratch with our very own brand new casting forms.
This cylinder head type is available in two separate versions. The standard cylinder head, suitable for a bore diameter of 39mm, is a 1 : 1 identical copy of the original item. The second cylinder head, suitable for a bore diameter of 47mm, was designed for use with the 75cc performance cylinder kit produced by PINASCO. All owners who require a little extra power for increased safety in modern traffic with the use of this cylinder kit were, up till now, forced to modify the existing cylinder head to fit. This is not a simple modification and for this reason we are having this type of cylinder head produced in a suitable size, including an optimised combustion area profile. Plug and play for all tuners!
Conclusion : Either the perfect supplementary component to complete your 75cc PINASCO cylinder kit or an ideal replacement for the original item!
SIP-TIP : Do not forget to order a suitable spark plug. For greater safety in modern traffic conditions the extra power provided by a PINASCO 75cc in combination with a SITO + exhaust system is indispensable!
