Polini EVO reeds box Derbi euro 2 / 3 / 4

Competition reeds box from the Polini brand.
The products of the Evolution series stand out for their high quality and excellent performance.
Thus, this reeds box is also equipped with carbon reeds. We recommend it for standard or modified motorcycles.

Improves gas flow, achieving a better response during acceleration.

It is installed as a replacement for the original box, without having to change any other part.

Essential for larger carburettors, and for motorcycles with a larger cylinder. Highly recommended for standard motorcycles, as the original reeds lose their good performance over the years.
