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.
With the 50cc standard cylinder busy roads are a dangerous place to be and you may just find yourself being overtaken by the postman on his push bike! To this end there are two reliable and powerful kits, both of which can be used with the original 50cc crankshafts. The 75cc kit is a powerful ROAD kit is with MALOSSI cylinders. The 112cc is the most powerful kit and it can also be used with the original 50cc crankshaft. The V50 Kit includes a Banana exhaust (75cc)/MALOSSI Banana (112cc); the kit for PK models include a SITO Plus (75cc)/POLINI Banana (112cc). The 75cc kit with 3-hole manifold is supplied with PK XL2 clutch friction plates. Both kits are 'plug&play' tuning kits and do not involve changing the engine case.
