Designed by the Polini racing department during the Polini Italian Cup and 100% Italian manufactured this Polini Evolution exhaust will enhance both the power and style of a Vespa Sprint or Primavera (125/150).
The exhaust has been developed especially for the 171cc Polini cylinder kit and is said to increase both acceleration and maximum speed.
That’s thanks to the internal design and compensation ‘plenum chamber’ located within the bulging down pipe, which increases performance throughout the rev range.
The Evolution exhaust isn’t homologated for road use though, so expect it to be slightly louder than an ‘ordinary’ road legal aftermarket system.
The muffler is made from black anodised aluminium, with a carbon fibre end cap and a stainless steel manifold. It’s a whopping 49% lighter than the standard exhaust system as well.
It’s available from all Polini stockists now and costs €390 plus vat. Or visit: Polini
