Passenger and luggage

Passenger and luggage: a loaded motorcycle bounces differently Your suspension was calibrated for a specific scenario: your weight, your motorcycle, your usual conditions. Every spring, every prelo...

Two systems, one goal

Frequencies: Suspension works slowly, the problem occurs quickly Every motorcycle suspension has a natural oscillation frequency, determined by the mass of the assembly and the spring's stiffness. ...

It looks more like a weapon than a suspension

Is the Gravitational Resonator more like a weapon than a suspension? The short answer is yes. And there's no hiding it. It needs to be explained. The mechanism they share A gun works on a simple pr...

Staying connected to the ground

"Our wheel's mission is a singular one: to remain connected to the ground". There should be no unsprung mass traveling through the air. We have the ground, we have the rubber, we have the cont...

MotoGP Technology

When motorcycling’s elite says yes, something has changed forever. On the world’s most demanding grid, where every tenth of a second is worth millions and no engineer accepts a solution that has no...

Your tire's bounce

The Rebound is generated by a compressible element called Air that fills an elastic containment element, called a Tire. The Tire Rebounds because it is filled with Air subject to compression, which...

Physics and Chemistry

Your body on the motorcycle: between ecstasy and survival. There's a reason you get hooked. Why every time you get home on your motorcycle, you're already thinking about the next ride. Why a Sunday...

No safety net

On a track, when something goes wrong, the system is designed to give you a second chance. Gravel slows your slide. Barriers absorb the impact. A medic is there in ninety seconds. On the road, none...

Transmission

The rebound you don’t see — but that destroys everything. When the tire bounces uncontrollably, the energy it creates doesn’t disappear. It travels — fast, relentless, and unchecked — through the e...

Frequency and regulation

Frequency and Adjustment: Tune the Gravitational Resonator to Your Motorcycle Every road speaks through vibration. The Gravitational Resonator lets you decide how your motorcycle listens. The key i...

Aquaplaning: what happens before you lose control

Rain does not instantly eliminate grip. It happens in stages. The final stage is obvious: the tire has already lost contact. The dangerous stage comes earlier. Grip is still there. But it is breaki...

What is chattering in motorcycles and how does it affect traction and stability

There's a feeling every rider recognizes, though few can name it. You're leaned over in a corner, smoothly accelerating out of the apex, and suddenly the rear wheel starts to chatter. It's not a sl...

Oversuspension system

"My system takes the initial impact energy, stores it, and then uses it to push the tire into the ground". The tire responds and stays glued to the ground because it is no longer full of energy tha...

Thermodynamics

"OVERSUSPENSION is a primary binary equation in which velocities, frequencies, spring load, and travel are related, approximating an almost absolute value with respect to the ballist...

Collaboration or Conflict

“The thinkers I owe a great deal to are two physicists who are no longer with us: Giuliano Preparata and Emilio Del Giudice. What do these two physicists have to do with Oversuspension? These two t...

Entropy and the motorcycle

Entropy and motorcycles: why stability is a matter of system order. In thermodynamics, entropy measures the degree of disorder of a system. Higher entropy means greater disorganization of the force...

Your credit

92 cm²: The only patch of rubber separating you from the asphalt For most people, a motorcycle means power, sound and freedom. But for those who understand dynamics, it is above all something far s...

Why a Gravitational Resonator is not a mass damper

A conventional mass damper achieves antiphase through passive resonance. The mass oscillates freely between two symmetrical elastic elements, and if the system is well calculated, its oscillation n...

Why your suspension isn't managing your wheel's rebound

During motorcycle use, your bike’s suspension is subjected to a continuous and variable workload. Road surface irregularities, changes of direction, and mass transfers under braking and acceleratio...

Highside

Highside: The Unforgiving Crash There are motorcycle crashes that allow for some leeway. They happen slowly, they allow for reaction, they leave the rider on the ground with time to process what ha...

Don't call me Mass Dumper

I am a Gravitational Resonator. Don't confuse me with anything else. There's a term that the engineering world has been using for decades to describe devices that add mass to a system to reduce its...

Hysteresis in the rear tire: the physics of grip that nobody explains to you

When the rear tire of your motorcycle touches the asphalt, something happens that goes beyond simple friction. The rubber deforms, absorbs energy, and, as it recovers its shape, returns only part o...

Unsprung mass

The rear wheel you can't afford to lose On a motorcycle, not all mass behaves in the same way. There is a fundamental distinction between what is supported by the suspension and what must stay conn...

The tire is also a spring. And nobody controls its rebound.

When we talk about suspension, we usually think about the shock absorber, the spring, the fork — everything between the chassis and the ground. But there is one element that also acts as a spr...

Why your motorcycle bounces more than usual: causes and what's really happening

When a motorcycle bounces, the first thing we look at is the suspension. That is the logical response. The shock absorber is there to manage vertical movement. If the motorcycle bounces excessively...

The flotation stage

The motorcycle’s natural pitching centre lies at the swingarm pivot, the point around which the rear of the bike oscillates as it absorbs irregularities in the terrain. It acts as the dynamic ancho...
