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” for Cross-Country, “HELIUM” for its incredible lightness!
1.2 kg for 120 mm of travel — simply put, 200 to 300 g lighter than world-class competition benchmarks, without any concession on steering precision, thanks to exemplary stiffness.
The Fastest
The vertical trajectory at SAG preserves all your speed, with no loss of horizontal energy. Root fields will never slow you down again!
The first aerodynamic XC fork. 25% reduced frontal area and a teardrop profile so you don’t lose a single Watt!
Anti-dive works for you, guaranteeing 100% of available travel under braking. Brake harder, later… Accelerate out faster!
The symmetrical wheel umbrella guarantees exemplary wheel stiffness, for flawless steering precision, even in 32″. Follow the shortest line!
With no stanchions or bridge, packing is impossible. Keep your energy!
The « F1 » Quick Release hub will be available as an option. For just 20 extra grams, it allows a wheel change in under 5 seconds, without removing the brake caliper. Whether you’re loading your bike or dealing with a flat tire, you’ll save even more time!
The Most Durable
Two parts, one connection. It doesn’t get simpler than that.
The carbon monocoque chassis is extremely resistant. Connected to the wheel axle / rocker assembly via a single oversized link, it forms the backbone of the X-ELIUM. It will never let you down!
The shock is isolated from steering loads. It works perfectly “in line,” which prevents premature wear. Add to that an absence of bearings and perfectly sized, tightly fitted axles, and you get exemplary reliability. It’s her job to take care of you, not the other way around 😉
The smoothest
The entire shock-absorbing kinematic chain is isolated from steering loads, not just the shock itself. The result: outstanding sensitivity and filtration. Say goodbye to pins and needles in your hands at the bottom of long descents.
The extremely low unsprung mass, roughly 10 times lower than a telescopic fork (0.1 kg vs. approximately 1 kg), brings reactivity and traction.
Anti-dive allows you to reduce compression preload. That means even more comfort, less fatigue, more performance.
The Most Versatile
The X-ELIUM goes from 29″ to 32″ with a simple hydraulic token in the shock. The standard may evolve — your fork is already ready.
You can already adjust its behavior “classically” by adding an air token. But you’ll also be able to directly modify the leverage ratio, progressivity, travel, or even the chassis’s anti-dive level, thanks to future kinematic kits. The X-ELIUM will evolve with you, for you.
These parts will be available anodized or in carbon. Style, weight savings, your X-ELIUM!
The most accomplished
An aerospace-grade design
The X-ELIUM applies dimensioning logic inherited from high-risk sectors such as nuclear and aerospace: every function is dissociated to be optimized to the maximum, pushing the limits of weight and integration without ever compromising safety or longevity. Every mm of the X-ELIUM has been calculated, tested, validated. You can trust it with your eyes closed!
A benchmark shock absorber
The X-ELIUM is equipped with the Fox Float SL Kashima: the highest-end shock on the market, and the most beautiful 😉. MOTION-specific tuning, 3-position handlebar remote. For those who prefer, fitting a RockShox SID Luxe remains possible. Either way, you’re on familiar ground: standard 190×45 mm format, usual adjustments, standard maintenance. No surprises!
Uncompromising manufacturing quality
Every material has been chosen for maximum performance: carbon for the chassis, CNC-machined and anodized 7075-T6 aluminum for the mechanical parts. The assembly is built for perfect integration — integrated or semi-integrated cable routing, no visible screws. Precision, down to the smallest detail!
