It is mounted to the engine case and rear wheel axle, increasing stiffness considerably, thereby preventing stress and torsion. Furthermore, it prevents a breaking and tearing of the engine case which may occur on high-end scooters. That is why you will find this high-tech part in scooter motorsport and Polini’s factory scooters.
Mounting is a piece of cake! However, plug & play is only possible with the following Polini exhausts: :
- POLINI SCOOTER TEAM 2
- BIG EVOLUTION 70cc
- BIG EVOLUTION 83/94cc
All other exhausts might require modifications.
