"I installed it on my BMW R nineT and the riding sensation is much smoother. The chassis feels more refined over uneven road surfaces."
"Where before I felt a jolt when going over a bump, now it feels like a cushioned and controlled impact. The bike settles much faster after a jump or irregularity."
"I was able to test my Kove 800X Pro with the Oversuspension installed and was amazed by the huge improvement. On a rocky climb where my companion got stuck, I went up without traction problems as if I had a special system."
"Unbelievable! I was a bit skeptical installing it on my CBR1000RR-R, but I can really feel how much more the tire grips the road surface."

FREQUENTLY ASKED QUESTIONS
OVERSUSPENSION is the first and only device in the world that controls tire rebound, thus exponentially increasing your riding safety and significantly improving your motorcycle's handling.
A motorcycle's shock absorber only manages the elasticity of the chassis with the rest of the rear end.
Oversuspension manages the elasticity of your tire with the swingarm.
We are talking about two separate elastic entities that work at different frequencies:
- A shock absorber averages 1.2 cycles/second.
- Oversuspension averages 18 cycles/second.
If I control the elasticity of the tire, I reduce the system's disorder.
With Oversuspension installed on your motorcycle, you will enjoy more traction, better braking, less riding fatigue, and less tire wear.
40% increase in traction
90% reduction in highside crashes
60% reduction in aquaplaning effect
30% reduction in musculoskeletal fatigue
We recommend that the Oversuspension kit be installed by a specialized workshop.

Oversuspension is a high-tech mechanical component.
It consists of a mobile central core of heavy metal, a tungsten alloy that slides in a ballistic-technology bushing.
An aeronautical-grade spring pushes this mass against a special polymer that changes its structure depending on the force with which it is compressed.
The impact energy pushes the wheel against the ground, up to 35 times in a single second.
By integrating our vibrational technology with an electronic suspension system, the amount of information to be managed received by the ECU is reduced, which optimizes its response and improves the overall efficiency of the suspension system.
In addition, our system also optimizes other electronically managed elements such as the ABS, reducing its workload and allowing it to operate more precisely and efficiently.
Un uncontrolled Tire Rebound generates Vibrations that are transmitted to your motorcycle's Transmissions and Gears.
Using Oversuspension in Cardan-type transmissions minimizes microgear Wear, known as Pitting. Avoid Costly Breakdowns.
The Oversuspension device can be adjusted depending on use, terrain type, and weather conditions.
The following adjustment scheme always refers to the device starting from fully open, towards the + sign.
ADJUSTMENT FOR 24-CLICK DEVICE
The adjustment for using the device in MOTOCROSS is as follows:
- On a sandy track, the device should be kept fully open, i.e., towards the + position. This way, the spring preload on the mass will be minimal and will better adapt to sandy tracks.
- On a muddy track, always keep the device fully open towards the + position.
- On a hard, dry track with shallow bumps, close the device 4 clicks towards the - position.
- On a hard, dry track with deep bumps, close the device 8 clicks towards the - position.
- On a Super Cross type track, close the device 6 clicks towards the - position.
The adjustment for using the device in ENDURO is as follows:
- On a timed track, close 2 clicks towards the - sign.
- On a slippery track and surface, leave it fully open towards the + sign.
- For Trial Cross: close 4 clicks towards the - sign.
The adjustment for using the device on a RACE TRACK is as follows:
- In wet conditions (WET), the device should be left completely open towards the + sign.
- On a dry track with undulations, close 4 clicks towards the - sign.
