The Original Polini muffler evolves into a RACING version, recommended for prepared Vespa 125 Primavera ET3 engines. It integrates with the original frame, both in terms of dimensions and aesthetics; its shape and the Polini writing in relief recall the iconic Polini mufflers, a distinctive brand for generations of Vespa riders.
The manifold with diameter increased to 29 mm and the first conical section have been redesigned; the final exhaust pipe has a new larger diameter. The new design guarantees high performance with a low but always pleasant noise level. The Original Polini Racing Exhaust is iinterchangeable with the original and allows the assembly of oversized tyres in size 3.50-10.
