UmK airtender, the suspension evolution

UMK AirTender is much more than a suspension system. It's a patented technology that has rewritten the rules of damping, created to eliminate the long-standing compromise between comfort and performance.

Designed, developed, and entirely manufactured in Italy, it represents the first major innovation born from Umbria Kinetics.

How it works

UMK AirTender is the result of engineering research, on-road testing, and a simple yet brilliant idea: act on the spring - the elastic heart of the suspension - not just on the hydraulics.

Traditional suspension systems have always forced riders to choose between a soft setup, capable of absorbing bumps but less stable, or a stiff one, precise and responsive but uncomfortable on rough surfaces. With UMK AirTender, that compromise no longer exists.

How it's made

At the core of the technology is a shorter, stiffer spring combined in series with an air system. This configuration allows the suspension to instantly adapt to the road surface, the load, and the rider's style - turning every kilometer into a safer, smoother, and more engaging experience.

UMK AirTender is a purely mechanical, patented system, free from electronics: no software, no sensors, no complexity.

Just precision engineering, transforming the suspension into an intelligent, versatile, and reliable component that performs perfectly on any terrain.

UMK AirTender adjusts to you, your motorcycle, and the road. Thanks to the combined spring + air system, the suspension dynamically alters its response - stiff and precise on smooth asphalt, soft and comfortable on rough terrain. Whether you're riding solo, two-up, or fully loaded, the suspension maintains the ideal setup at all times.
The hydropneumatic system absorbs bumps instantly, reducing impacts and vibrations. The result is less fatigue, greater riding pleasure on long trips, and exceptional comfort even on uneven roads.
UMK AirTender enhances the dynamic behavior of any motorcycle. The stiffer spring increases responsiveness, traction, and stability under braking and cornering. On wet roads or at high speed, it ensures maximum grip and precise control.
The accumulator is entirely designed and manufactured in Italy. An internationally recognized patent that brings Umbria Kinetics' mechanical excellence and innovative capability to the world.
No invasive modifications or electronics are required. UMK AirTender can be installed on both OEM and aftermarket shock absorbers, including semi-active electronic systems such as ESA. It's a simple, long-lasting upgrade that brings a tangible step forward in suspension performance. If you change motorcycles, you don't need to buy a new system: the accumulator can be reused on your new bike, preserving part of your investment. Other components are model-specific, ensuring optimal performance every time.

UMK AirTender is not just a technical upgrade — it's your entry point into the Suspension Evolution.

It makes every motorcycle safer, more versatile, and more enjoyable to ride.

Whether you're a long-distance traveler, a sport rider who loves cornering, or simply looking for superior comfort, UMK AirTender adapts to you and your style.

This is more than improving a suspension system — it's about changing the way you experience the road. The right suspension, at the right time. Always.
