TORSEN WD swing arm reinforcement by POLINI Motori vertical minarelli engine MBK / YAMAHA (booster rocket, bw's ...) after 2004

With the birth of this quality piece, POLINI has set the bar very high! Inspired by MOTOGP competition forks, the TORSEN WD for any vertical minarelli MBK / YAMAHA engines will harden the crankcase while avoiding twists which on large engines can lead to the crankcase breaking. What will the TORSEN WD POLINI bring you? Engine strength and increased road holding, all with a sober design, ultra racing and a featherweight.



Thanks to this connection between the chassis and the rear wheel, the TORSEN WD gives you better driving stability and better control of the scooter in curves while at the same time reducing asymmetric tire wear.



Straight out of the POLINI factories, it is of course a Made In ITALY piece with a very high quality!



The TORSEN WD is fixed at the front with two screws at the standard attachment point of the pots and at the rear with a nut which is fixed on the existing wheel axle. The particularity of this rear attachment is that to ensure a better association between the TWD bearing and the axle nut, an axial compensator is used in order to correct the axis of the arm to avoid any vibration or malfunction.



Finally, we will say that this piece is a must! Whether for its quality, its design, its practicality, it is a safety element for your 2 wheels. Supplied with screws, washers, silent blocks, ...
