The 200cc PX motor provides THE ideal basis for all VESPA large or wide frame tuning projects. A tuned PX 200 motor equipped with a MALOSSI 210cc cylinder, a 60mm stroke crankshaft and a SIP 'Road' exhaust system provides you with a cruising speed of 110 km/h (almost 70mp/h) and a potential top end speed of up to 125km/h (almost 80mp/h). All the SIP touring VESPA's are equipped with tuned PX 200 motors which make our annual tours, with an average of 2500 km (over 1600 mls.) in five days possible, which proves that you can visit surrounding countries on older VESPA models without serious problems with reliability. The Austrian and German tuning scenes have shown that power outputs of up to 40 PS and more are possible, without the use of nitrous injection. The basis though, remains the PX 200 motor, making it the premium VESPA motor of all geared VESPA models. Everyone should have one at home, even if you put it on the mantelpiece.
Regrettably PIAGGIO no longer produce the PX 200 motor, despite the fact that we were persistent in our efforts, over many channels, to urge them to reverse this decision, we were close to resignation. This all changed though as in 2010 we became the official MALOSSI importers for Germany and we were presented with a new, exciting opportunity... MALOSSI now produce these crankcases after consulting PIAGGIO for official approval. The MALOSSI version has the exact dimensions and specification as the original PIAGGIO item but with an even better high quality casting process. All recesses such as the porting channels and the carburettor inlet are precision CNC machined. All vibration damper rubbers are included and installed. Every single casing unit then undergoes the exacting MALOSSI quality control process to be sure of minimal production tolerances for bearing surfaces etc. being maintained.
Conclusion: In the end these motor cases are still original PIAGGIO but with an extra touch of high end quality provided by MALOSSI.
Helpful hint: When mounting the kick start shaft and return spring, make sure that the shaft is not pushed away by the small half. If so, we recommend the use of the original kick start shaft and return spring. This can also happen with original PIAGGIO and MALOSSI crankcases.
SIP-TIP : Do not forget to order new oil seals, a gasket set, bearings and all relevant peripheral items for safe and enduring use of your newly assembled motor. The oil pump and electric starter recesses may also require sealing. Last but not least, fresh gearbox oil is also more than a good idea.
