X-ELIUM
Our Vision
MOTION is more than a suspension brand… We are a research and engineering company specializing in vehicle dynamics and suspension systems.
For more than 10 years, we have been designing and developing the suspension systems of tomorrow’s vehicles—from bicycles to lunar rovers, including autonomous robotic platforms.
With the X-ELIUM, we have put technological innovation at the service of pure performance.
The X-ELIUM was designed from scratch with one goal in mind: to become the world’s best XC fork, without compromise.
The X-ELIUM pushes the boundaries of performance. It sets a new benchmark, redefines expectations, and marks the beginning of a new era.
Why ?
Over 40 years of development, telescopic forks have reached an exceptionally high level of performance.
However, their inherent design limitations now prevent any significant leap forward.
The telescopic design fundamentally limits the stiffness-to-weight ratio.
It is impossible to build a telescopic fork that is both perfectly precise and exceptionally lightweight.
Brake dive compromises both stability and bump absorption.
Under hard braking, a telescopic fork can lose up to 80% of its available travel, resulting in a significant loss of suspension performance when it is needed most.
High unsprung mass limits suspension sensitivity and bump absorption.
The lowers, spring, and damping system are all unsprung, accounting for up to 65% of the total weight of a telescopic fork.
The fork arch restricts mud clearance.
It also limits maximum tire and wheel size, forcing a compromise between weight, stiffness, and packaging.
The telescopic design causes a significant loss of grip and comfort under load.
Braking, impacts, and cornering forces generate friction within the system, reducing suspension sensitivity and forcing a compromise between performance and durability.
Wheel kinematics are fixed, leaving no room for performance optimization.
A telescopic fork is constrained to a straight wheel path with a constant 1:1 leverage ratio, severely limiting suspension tuning and dynamic performance.
A telescopic fork is constrained to a straight wheel path with a constant 1:1 leverage ratio, severely limiting suspension tuning and dynamic performance.
These inherent limitations prevent telescopic forks from fully achieving the core goals of modern XC racing: lightness, performance, and reliability.
To push the boundaries even further, a completely new technology and a fundamentally new architecture had to be invented.
The Lightest
The “X” stands for Cross-Country. “ELIUM” is inspired by helium—symbolizing its incredible lightness.
At just 1.2 kg for 120 mm of travel, the X-ELIUM is 200 to 300 g lighter than the benchmark forks used at the highest level of XC racing—without any compromise in steering precision. Exceptional stiffness delivers uncompromising control and confidence.
