Swing arm Polini Torsen WD engine brace

The extreme forces associated with tuned engines often place other components under too higher 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 swing arm 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 and Scooter Team.
