Polini Torsen WD Swingarm Piaggio ZIP SP 50 2T

Polini Torsen WD swingarm for Piaggio ZIP SP 50 2T.

The TORSEN WD swingarm, thanks to its lattice shape, gives rigidity to the engine casing to prevent abnormal flexing, which in this type of engine can break the casing. In addition, by adding some engine silentblocks to support the axles, it prevents flexing and excessive pressure, which improves the efficiency of the transmission.
The system is more rigid, which increases stability when riding the motorcycle and in corners, while at the same time reducing asymmetric tyre wear.

The silencer remains close to the vehicle, allowing the motorcycle to lean on the track at incredible angles without the silencer touching the asphalt.
The TORSEN WD must be mounted exclusively on Polini Evolution P.R.E. engines.
