Aluminium racing cylinder for 125-150 cc Vespa Largeframes
German specialist SIP Scootershop has introduced a SIP performance 125 cc cylinder that allows all Vespa Largeframe scooters to be converted into a two-wheeler in the 125 cc class with updated, contemporary performance values.
Particularly suitable for Vespa riders who have a licence with a 125 cc engine capacity limit, the powerful 125 cc coated aluminium cylinder is compatible with 2- and 3-channel engines.
Co-founder and CEO Ralf Jodl told IDN: "Unfortunately, classic 125 cc scooters in their original condition are no longer up-to-date in terms of performance. With the SIP performance 125 cc racing cylinder, this can be easily changed and even 125 cc licence holders can safely keep up with the traffic.
"The cylinder is made of aluminium and has a coated raceway. The cylinder draws its power from its sophisticated transfer system. The mixture enters the combustion chamber through six transfer ports and escapes back into the exhaust through three exhaust ports.
"The head is fitted with eight fittings and additionally sealed with an O-ring. The exhaust is made of steel and is bolted to the cylinder. The piston is coated to protect the piston skirt during the running-in phase."
The cylinder is always installed with a 4 mm thick spacer between the cylinder and the crankcase. Two different spacers are included in the kit. One is for mounting on a three-channel casing, the other allows the cylinder to be mounted on a two-channel casing. The kit includes paper gaskets of different thicknesses for both types of housing, which can be used to adjust the height of the cylinder.
