Cylinder Kit 125cc for Vespa

Ø 55,0mm, aluminium, 5 ports,
stroke 52mm, 2 piston ring(s),
w/o cylinder head,
with ASSO piston, made in

Il modello sportivo, the Vespa T5 125ccm. On the market since 1985, the T5 is a witness of innovation in design and performance. The T5's well thought out sporting and performance oriented motor concept is alive and kicking today with an engaged and active circle of fans.

Unfortunately, PIAGGIO has stopped producing many T5 replacement parts. SIP is staying on the ball; which means we can offer original cylinders "made by GILARDONI". High quality cast aluminum, topped with a robust nicasil lining, 5 transfers, (T5 = Traversi 5) and a generous exhaust diameter form the basis for this 125ccm Vespa T5 jewel. The pistons are made by well known manufacturer ASSO and was first in the VESPA hall of fame with 2 thin, 1mm thick break proof piston rings. All in all, a thermally stable, durable and yet sporty cylinder.

Perfect to update your scoot, we highly recommend a modified cylinder head with optimized combustion chamber and compression. The highlight here is based on CNC milled heads from MMW.

Conclusion: This is the right address for those looking for an original cylinder in first level quality.


Aluminum/ 55mm bore/ 5 transfers/ 123.54cc

Aluminum cylinder, 52mm stroke, 5 transfers, pistons with 2 x 1.0mm piston rings and chromed race, compression 11.3:1.


SIP TIP: W3CC spark plug, ignition timing 19°, main jet SI 24/24G 108 and a new base gasket are a must,

modified MMW cylinder head, COSA clutch , racing exhaust as SIP Performance recommended


Norrie Kerr “Tuning Vespas- The Norrie Kerr Way”:

"Of course the icing on the cake is the T5. The barrel is a work of art"
