DetailsOriginal, unsupported engine cases and variator covers are not made to withstand the enormous strain produced by highly tuned engines. Additional strain can be experienced due to cross-country rides and stoppies. The worst-case scenario is that the engine casing brakes or the bearings get knocked out.
The Polini TORSEN WD increases stiffness considerably, which prevents flex and stabilises engine case and wheel suspension. At the same time, it reduces asymmetric tyre wear and makes for better steering characteristics.
This additional swing arm is a direct fitment with the POLINI BIG EVO, POLINI FOR RACE 2 and SCOOTER TEAM exhausts; other exhausts may require modifications.
