Tuning Kits: The Easy Way into Vespa Tuning
The tuning jungle is big, the range of products available is massive and the possibilities are almost infinite. Over the years, a range of most wanted combinations have crystallised in the area of road tuning which fulfil the same requirements: a clear increase in performance, a better exhaust performance and higher top speed, good durability, easy installation, no or limited changes to the engine case, conversion-back possibility, and a good price performance ratio.
The Tuning Kits include most customers' and the SIP team's favourite combinations. They are a very good upgrade for the corresponding engine. They are sporty but great for touring use at the same time. They include all the necessary small components and are therefore the ideal first step for anyone with no previous knowledge of tuning whatsoever.
The ROAD Kit is the starter kit. With this kit, attention has been paid to providing a low cost package which still provides superior acceleration and a higher top speed.
The SPORT Kit contains a high rev cylinder and frequently includes a bigger carburettor. This results in more power and higher speed. The carburettors mostly come without separate lubrication. Those who mix themselves know what happens in the combustion chamber.
The carb. jetting is an approximate value and at 0 m above mean sea level, Hamburg differs from the alps. Both kits represent a sound basis for further tuning. This is always associated with a change of crankshaft, however, which involves opening the engine. If the engine is already old and has done a lot of kilometres, an engine overhaul is recommended. If you're going to open the engine, you are advised to take the opportunity to extend your tuning job to include the crankshaft and gear components.
Conclusion: Tuning kits enable beginners to save money and stress and to benefit from the tuning experience the SIP team has gained over many years.
The premier class of the smallframes is also great for tuning - with enduring results. A trip to Italy with the smallframe? Utopia becomes reality: The ROAD kit makes it possible and you can even try overtaking at a pass like the Stilfser Joch. The Road kit with the 3-hole manifold is supplied with PK XL2 clutch friction plates. The SPORT kit includes the MALOSSI 136cc. At a realistic price you get a potent force which you will have to tame! Both kits are 'plug&play' tuning kits and do not involve changing the engine case. In combination with a 125cc crankshaft, these kits can also be installed in 50cc smallframes. The Tuning Kit POLINI ESC Class 5 is the plug&play solution for the standard class of the European Scooter Challenge. Powerful, reliable and perfect if you fancy giving it a try on the ractetrack but have a tight budget.

TUNING KIT POLINI ESC Class 5: racing cylinder POLINI 130cc, carburettor kit PHBL 24/25 with slide valve manifold, racing exhaust MALOSSI (V50)/POLINI (PK), primary gear ratio 2.56, reinforced MALOSSI clutch plates, spark plug, 3 main jets, nut/washer clutch+primary gear cog, ignition timing approx. 17°
SIP-TIP: A SIP VAPE ignition is a perfect add-on. A more powerful racing exhaust, a racing crankshaft and a reed valve carburettor kit are the next steps.
