To stay stuck to the ground

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

MotoGP Technology

When the motorcycling 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 hasn'...

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 loopholes

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

Transmission

The rebound that destroys what you don't see When the tire bounces uncontrollably, the energy it generates doesn't just disappear. It has to go somewhere. And it does. It propagates upwards through...

Frequency and regulation

Frequency and Adjustment: How to Tune the Gravitational Resonator to Your Motorcycle To understand how Oversuspension is adjusted, there's a physical concept that explains everything: frequency. Fr...

Hydroplaning: what happens before you lose control

Rain does not instantly eliminate grip. It does so in stages. And the most dangerous stage is not the last one, when the tire has already lost contact. The most dangerous stage is the one before: w...

What is chattering and why does it destroy your confidence in corners?

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 referents to whom I owe a great deal 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...

Entropy and 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 forces...

Your credit

92 cm²: The only piece of rubber separating you from the asphalt For most people, a motorcycle is power, sound, freedom. But for those who understand dynamics, a motorcycle is above all this: two p...

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, mass transfers under braking and acceleration. T...

High side

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

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. It absorbs energy. And when it recovers its shape, it does not ret...

Unsprung mass

The rear wheel you can't afford to lose In the dynamic architecture of a motorcycle, not all masses behave the same. There is a fundamental distinction between what floats on the suspension and wha...

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

When we talk about suspension, we 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 spring and that a...

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. It's the logical response. The shock absorber is there to manage vertical movement. If the motorcycle bounces excessively, i...

The flotation stage

The motorcycle has its natural pitching center at the swingarm pivot, that pivot point around which the rear of the bike oscillates and absorbs terrain irregularities. It is the dynamic anchor of t...
