Torsen swingarm WD Minarelli horizontal with Polini disc brake

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 bike and in corners, while at the same time reducing asymmetric tyre wear.

The silencer remains close to the vehicle, allowing the bike to lean on the track at incredible angles without the silencer touching the asphalt.
The TORSEN WD can only be installed together with the new range of Polini Big Evolution competition exhausts or the For Race 2.

NOTE! On Yamaha Jog models, it can only be installed in combination with a Minarelli engine with disc brake!

Includes bolts, silentblocks, tools, etc.
