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 what stays glued to the asphalt.
The rear wheel belongs to the second group. It is unsprung mass: a component that operates without the elastic protection that the chassis and rider have above it. It directly receives every imperfection of the terrain, every variation in grip, every force the asphalt exerts on it.
And it has a mission that cannot be interrupted: to remain in contact with the ground.
Not intermittently. Not most of the time. Permanently. As if magnetized to the asphalt. Because every fraction of a second that the rear wheel loses that contact, the system enters a territory where the laws of physics rule and the rider loses control.
What happens when the wheel loses grip
Loss of rear wheel grip is not a single event. It triggers a chain of consequences ranging from compromising to fatal, depending on the speed, angle, and moment it occurs.
Drifting. The rear wheel loses traction and begins to slide sideways. In the hands of an expert rider and under the right conditions, it is controllable. In any other scenario, it is the beginning of a progressive loss of control.
Tail wags. The lateral oscillation of the rear of the motorcycle. When the wheel alternately regains and loses grip, the movement propagates to the chassis in the form of wobbles that the rider struggles to compensate for. Each wobble is more difficult to correct than the last.
Highside. The most violent and treacherous. It occurs when the rear wheel, after losing grip and sliding, suddenly regains it. The energy accumulated in the slide is abruptly released, launching the rider over the motorcycle. It is one of the most dangerous crashes in motorcycling. It gives no warning. There is no time to react.
Oversteer. The rear of the motorcycle leads the front in a turn. The motorcycle turns more than the rider intended. The angle closes. The margin disappears.
Four different scenarios. One common origin: the rear wheel that stopped being magnetized to the ground.
The solution is to prevent it from happening
Oversuspension acts directly on the unsprung mass, counteracting in real time the forces that cause the momentary lift-off of the rear wheel. When the tire tends to lose contact with the asphalt, the Gravitational Resonator generates a counter-phase response that pushes it back down.
It does not manage grip loss once it has occurred. It prevents it from occurring.
The rear wheel remains where it should be: magnetized to the ground, in permanent contact with the asphalt, transmitting traction and receiving information. With Oversuspension, drifting, tail wags, highside, and oversteer are not corrected. They are prevented.
Because the best time to prevent a fall is before it starts.
Oversuspension does not correct falls. It prevents them. → FIND YOUR KIT HERE
