Polini Evolution 2 Exhaust Minarelli AM6 / Derbi

Exhaust Derbi Senda / Beta 50 Evolution 2 for Minarelli AM6 and Derbi euro 3 engines from the manufacturer Polini.

The Polini exhaust is designed as a sport/racing line for 50cc 2T enduro/supermotard type bikes, aimed at improving engine response and revving compared to an original system, with a fuller performance in the useful rev range (in this type of sport exhausts, it is common to gain acceleration, rpm, and some top speed when the carburetion is properly adjusted).

In stock configurations, it may require tuning (carburetion) for the change to be noticeable, while with sport kits 50-70cc this type of exhaust usually performs best.

To accompany it, many distributors recommend as a base a Carburettor 19 mm (or 19/21 mm depending on setup) in lines of this orientation, to properly feed the assembly when aiming for performance.
