In this video, Elvis from SIP introduces viewers to a very special cylinder for smallframe Vespas: the 125 cc racing cylinder from SIP PERFORMANCE. This upgrade transforms the “Fuffi” into a 125cc Vespa with significantly more power and performance. And the best thing about it? Thanks to a parts certificate from the TÜV, the cylinder is absolutely roadworthy and can be ridden without the need for an expensive extra test.
In a nutshell: the driver’s license makes all the difference
The 125 cc class is very popular and offers an ideal introduction to the world of motorized two-wheelers. Depending on national regulations, 125 cc vehicles can be ridden from the age of 16 with a special motorcycle license. In some cases, even a car driver’s license is sufficient.
Elvis shows you how it’s done!
The SIP Performance 125 cc cylinder kits offer the possibility of building engines in accordance with certain driving license requirements that still deliver particularly good performance. While the standard engines of the Vespa Smallframe models with 125 ccm only achieve 5.6 hp and a top speed of 85 km/h, the SIP Performance 125 ccm kit allows a higher performance to be achieved. This is comparable to the 133 to 136 cc gray cast iron tuning cylinders that have often been used since the 1990s.
However, it is important to make an agreement (not a test!) with the relevant licensing authorities before using on public roads.
The SIP Scootershop is the perfect place to go for tuning for all Vespa models and spare parts for all possible areas. So anyone who would like to have their Vespa a little faster should definitely check out the large range!
The good news about this cylinder just keeps coming. Here are a few technical highlights: The cast iron cylinder is characterized by a bore of 55.6 mm and a stroke of 51 mm and has a displacement of 123.83 cc. With six transfer ports and a flat piston equipped with two piston rings, the cylinder offers robust performance. The cylinder head is secured with eight screws and the distance between the exhaust studs is 52 mm. Four base gaskets are also included in the scope of delivery. Another advantage of this cylinder is that it can be fitted to the engine housing without any modifications.
You can watch Elvis push his 125 onto the test bench in the video below and achieve amazing results – 8.2 hp at the rear wheel and 9.3 hp at the engine are more than decent. It’s the first cylinder ever with which you can start without the annoying, expensive and time-consuming process of getting your own certificate. That’s really fantastic news!
