Polini For Race 4 Exhaust for the Minarell Vertical
One of our favorite pipes for the Prebug Zuma.
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 high revving Polini Corsa cylinder.
Fits most Minarelli Vertical engines including:
Yamaha Zuma Vertical
