swing arm POLINI Torsen WD engine brace for Minarelli horizontal long

The extreme forces associated with tuned engines often place other components under too high a load. The boomerang shape of the TORSEN WD, inspired by the world of MotoGP, gives additional support to the engine block, thereby reducing irregular movement or asymmetric tyre wear. This swingarm also offers greater stability that can be felt in any corner. Note: The TORSEN WD swingarm works only with Polini exhaust systems if the system is from the Big Evolution range, For Race 2 or Scooter Team.
