Torsen Swingarm WD Minarelli vertical >2004 Polini

The new Polini Torsen WD swingarm is inspired by Moto GP but is installed on 50cc competition scooters.

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 a bearing to support the axles, it prevents flexing and excessive pressure, which improves transmission efficiency.
The system is more rigid, which increases stability when riding the motorcycle and in corners, while also reducing asymmetric tire 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 can be installed exclusively together with the new range of Polini Big Evolution competition exhausts or the For Race 2.
