Inspired by the MOTO GP swinging arm this Polini strengthening brace is for Piaggio Zip SP. It is mounted to the engine case and rear wheel reducing stress and increasing stiffness considerably for improved structure, cornering and handling.

Fitting is easy, However, plug & play is only possible with the following Polini exhausts:

Scooter Team 2
For Race 3
Big Evo 70cc
Big Evo 83, 94cc

This kit will fit other exhausts but will likely require modifications.
