Description
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
