Polini For Race 4 Exhaust for the Minarell Horizontal

Polini went back the drawing boards and engineered a totally new For race 4.

Like the previous For race 3 this exhaust still delivers plenty of low down torque all while still delivering the revolutions you are looking for.

A perfect combination for the Polini Corsa cylinder.

Fits most Minarelli Horizontal engines including:

2002-2011 Yamaha Zuma

Aprilia SR 50 carb version
