These are BGM anti dive bracket set’s for Primavera type forks, it fits all Vespa Smallframe with short swingarm V50, 50N, Special, V90, V100, SS50, SS90, SR50, PV125, ET3 and Motorvespa Smallframe models.
This kit shifts the center of rotation of the shock absorber to the height of the center of the wheel.
Thus the shock absorber is directly controlled without a transmission ratio. This improves both the response and the original quite pronounced brake pitch.
The damper does not penetrate so fast, the vehicle is safer to drive.
