Single cylinder 4 stroke scooters like the Piaggio Zip, Fly and Vespa S and LX etc have been hampered in their already feeble performance with some other niggles just to make sure you really know that you are going slow enough for a cyclist to overtake you.
The obvious restrictions are in the variator and the exhaust system, which are easily changed or removed, here is a link to show you what should be removed from the transmission on a 2 stroke engine which is exactly the same principle for your 4 stroke, follow step 4 and 5 .
The exhaust system also needs liberating but don't expect an increase like you would receive on a 2 stroke which in some cases could be double the top speed. A good system which is stealthy in it's appearance is the Tecnigas Silent Pro . This offers low noise, improved top speed and freedom for the engine to rid itself of the gases.
The CDI is key to achieving more top speed, previously the only way to get past the electrical restriction was to cut part of the circuit on the CDI and re seal the unit. Now you can unplug the old unit without visiting a Piaggio specialist and plug the new one in it's place, the offer price is only £31.00. Although only an approximate figure we would expect you would see between 45 to 55mph with the components mentioned.

Tecnigas exhaust systems for scooters and mopeds are becoming increasingly more popular as people realise what we have been seeing for many years.
The new 4Scoot for the Honda SH 125, PS i 125 and @125 i adds to the range and keeps within the criteria you would be looking for when replacing a system on your maxi scooter.
The 4 Scoot stainless steel exhaust is a good choice for a few reasons, it offers a good performance increase over the standard unit. The longevity of the system is increased due to the materials used to make it and the price we are managing to offer this for is much lower than the original Honda scooter exhaust.
