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.
