Legal Tuning Kit from SIP PERFORMANCE for 125 cc Vespa Models.

Plug and play in a new dimension: With our kits including parts certificates, we now also offer the quintessence of years of tuning experience on the road - as all-round carefree packages for easy registration in the vehicle documents.

Since January 2013, there is no longer an 80 km/h limit for class A1 light motorcycles. This opens up completely new possibilities in the field of legal tuning. As original PX80 Cylinders have not been produced for a long time, anyone looking for a replacement Cylinder for their PX80 had to either fall back on a used part or install a Racing Cylinder with 135 cc or 139 cc. However, the latter was not a legal option for riders with a "small license" up to 125 cc.

• Lower costs for registration
• Secure basis for registration without problems with the test center
• Legal, safe and fast on public roads

The SIP 125 cc Road Tuning Kit, which we have legalized with a parts certificate, provides a remedy. It offers a significant increase in performance, better exhaust and a higher top speed with good durability and easy installation - without any changes to the Crankcase. Even a retrofit is possible.

The SIP 125 cc Road Tuning Kit was developed by the SIP team and is a very good upgrade for 80cc largeframe engines. It also includes many effective small parts such as the Float Chamber with larger needle valve and the special Throttle Slide, which makes it easy to get started even for those who are not yet familiar with tuning.

The centerpiece is the high-torque SIP 125 cc Cylinder in combination with the larger SI24 Carburettor of the PX200 Models. The result is more power and more speed. The kit is available in a version with an enclosed carburettor with separate lubrication and without separate lubrication.

If the Engine is already old or has many kilometers behind it, an engine overhaul is recommended before the conversion. Crankshaft bearings, Oil Seals and Cruciform in particular are typical wear parts on Vespa two-stroke engines. Both kits are also a good basis for further tuning. However, it should be noted that the parts certificate loses its validity in this case. If the Engine is opened up anyway, it may be a good idea to change to a better Crankshaft, for example. And if you are already operating on the open heart, the tuning should be rounded off sensibly with tuned transmission components.

Conclusion: The SIP Tuning Kits with parts certificates offer beginners and advanced riders reliable performance from years of tuning experience and can be easily registered thanks to parts certificates - for a good feeling also with regard to the StVZO.
