Supreme Technology Oversuspension Mass Damper
Husqvarna 701 Models (all)

DESCRIPTION:

Introducing Supreme Technology, an Italian company with over 35 years of experience in the design, development and processing of components for the motor sports, motorcycles and cars as well as in the aerospace sector.

Over Suspension is a special resonator capable of removing the resonances of the rear swingarm group and giving the vehicle more stability, traction, braking and comfort. Additionally the oversuspension mass damper facilitates the dynamic operation of the suspension, and greatly improves driving safety in every condition, for example reducing the possibility of highside on the track by up to 90%.

The STO resonator is used in Moto3, Moto2, World Superbike, Supersport 600, FlatTrack, American championships and many European championships, but beware it's not a normal MassDamper.

This device was developed in collaboration with Barni Ducati Team and the riders Michele Pirro and Michael Rinaldi who both use it in the race. It has been used and tested very successfully on the street with normal bikes, and on the racetrack, giving many advantages, though first of all is safety. The device has just been recognized by the Italian Motorcycle Federation as an important element of safety and has consented to its use in competitions in all national championships.

DETAILS:

During the use of the vehicle (whatever it is), the suspension is constantly stressed by the unevenness of the ground and by the change of the trajectory of the tire. Normally it is thought that these stresses are completely managed by the suspension, in truth this happens only partially because the suspension calibration is static and does not change over time while the stresses vary over time and in their intensity.

Oversuspension takes care of managing both the stresses that the suspension receives and the elastic rebound of the tire, which, when out of phase with respect to the trajectory of the suspension, generates anomalous forces that affect the suspension. Furthermore, the device also deals with attenuating the oscillatory frequencies generated by the ABS intervention and the Traction
Control.

The Oversuspension project for street bikes consists of a revolutionary adjustable gravitational resonator that allows to mediate the frequencies generated by the suspension unit when the shock absorber is not effective, improving driving precision, traction, braking and generally the stability of the vehicle , contributing to vehicle safety both on the road and on the track.

In particular, this device functions to regulate or cancel the resonant frequencies of the oscillating arm when this passes from a state of unsprung mass to suspended mass, thus drastically reducing the rebounds of the pneumatic group on the asphalt.

The device also operates during the intervention of the ABS system, greatly improving braking, and during the intervention of the traction control systems for which it is of absolute benefit, then improves the electronically controlled suspension, where mitigating the occasional resonances makes the auto-calibration of the suspension more precise.

In case of wet conditions, it is able to reduce the phenomenon of aquaplaning, in the presence of uneven ground to reduce the structural stress of the vehicle.

Calibration: Performing the calibration is very simple:

1. Turn the red ring towards the (sign +) until it reaches the stroke end, in this way the spring that contrasts the mass will have the minimum calculated preload and the mass will resonate to agreater amplitude and a lower frequency.

2. Use the vehicle and try to pay attention to the sensation that you feel regarding the swinging of the rear swingarm in roughterrain, entry into corners, sharp braking and travel of the bent curve.

3. Turning the red knob towards the (sign -) you will notice thatthe sensations that were perceived before will vary and will be more or less intense. Then rotate to the position where you will notice less oscillation of the rear and you will have a more direct feeling with the suspension.
