Crankshaft TAMENI for Vespa T5

pin 16mm,
con-rod pin: 20mm, with
/without separate

If you restore a long neglected Vespa motor then you will often find the crankshaft immobilised due to rust or corrosion. The bearings and oil seals are often worn out and woodruff key recesses are no longer serviceable. If you are overhauling your motor and your existing crankshaft displays any of these signs of age, it should be replaced.


We have high quality standard crankshafts available that are made in Italy. MAZZUCHELLI and TAMENI, both based near Milan, have been delivering premium quality Vespa crankshafts with excellent value-for-money, for decades. They are 100% identical to the originals in appearance, production quality and port timings. Additionally the TAMENI have an extremely good pre combustion compression. TAMENI have specialised in the production of standard crankshafts for the earlier models of Vespa up to and including 1951. These are made in small production runs and have proven their merit countless times with the finest production quality, quietness and value-for-money.


Over the years PIAGGIO have used both low and high primary compression crankshaft setups. The early models also had bronze bushes instead of bearings installed on the con rods of their crankshafts. We have categorised the crankshafts according to manufacture information and original PIAGGIO parts catalogues. We provide all the specific data, necessary to identify the particular details of exactly the item you require for your type of engine: Ø gudgeon/crank pin, conrod length and stroke. Please check all measurements of your existing crankshaft against these listings before ordering to ensure you receive the correct item. All of the above crankshaft details and more are available at our website


Conclusion: Perfect for complete motor overhauls and mild motor tuning projects.


SIP-TIP: New crankshaft bearings, oil seals and the suitable woodruff keys, gasket set, nuts, safety washers are a must. To make the job a lot easier we also have all relevant crankshaft assembly tools available at our shop (PART No 27338000, 21071000, 18119000).


SIP customer Olov S., Malmö, Sweden:

"Incredible. I am at the moment renovating two GS150, and in both cases the crankshafts where bad. I believed that it would be impossible to find new ones for such an unusual model, but you had them! And for a reasonable price, comparable with the cost for a renovation of the old!!! "

We have Vespa T5 crankshafts in stock for both pre-mix and auto-lube motor systems.


The essential difference between the two is the position of the woodruff key recesses. The auto-lube version has the woodruff key recess positioned closer to the bearing, so ensuring the secure positioning of the oil-pump drive spacer.
