Escape For Race 4 70cc Minarelli horizontal

Polini For Race 4 exhaust for Minarelli Horizontal engines.

The Polini FOR RACE exhaust pipes have been modified over time, adapting and improving their performance, up to the current version 4.

The exhaust manifold has been completely changed, coming very close to the Big Evolution exhausts. In this way, it was possible to work using telemetry and the data collected on all the tracks of the Polini Italian Cup to develop and maximise engine performance both in acceleration and in power delivery.

The exhaust is made up of 7 sections of different sizes, all hand-welded together (1 more than the previous model).

The new line also allows for easy installation of the Polini TorsenWD swingarm. The black silencer, made of lightweight alloy, laser-printed with a direct discharge internal core, can be disassembled to replace the soundproofing material.
