KYB Unveils Prototype Mountain Bike Suspension
Trail riders get an early look at a new inverted fork and rear shock, with the fork described as nearly ready for production.
Updated on Nov. 6, 2026 in Hiking

Japanese suspension brand KYB has unveiled a prototype inverted mountain bike fork and a coil-sprung rear shock, shown on a Marin Alpine Trail eMTB. The fork is described as ready for production, with aftermarket availability likely in Europe and original equipment placements planned for North America.
Why it matters
For trail riders, suspension choices shape comfort, control and how much effort a long descent demands, so new options from a motorcycle-racing suspension specialist widen the field. The rear shock is still behind in development, so the full setup is not yet final.
This is a prototype display rather than a performance study, so no test results or measured weights were reported. The fork is shown on a 160mm-travel Marin Alpine Trail eMTB with a 170mm fork, and its thinner uppers are compared against recent inverted forks from Cane Creek and Fox.
The players
KYB
A Japanese suspension brand best known for motorcycle race suspensions, now expanding into bicycle and four-wheel suspension products.
Marin Bikes
A bicycle manufacturer whose Marin Alpine Trail eMTB is the platform used to display KYB's prototype fork.
Cane Creek
A bicycle suspension maker whose recent inverted forks serve as the comparison point for KYB's thinner fork uppers.
Fox Racing Shox
A bicycle and motorcycle suspension manufacturer whose recent inverted forks serve as the comparison point for KYB's thinner fork uppers.
The details
The fork legs clamp into the uppers, which could make servicing easier. Its coil springs are paired with speed-sensitive compression damping, and the right leg carries separate compression and rebound adjusters. The rear shock adds adjustable spring preload and low-speed rebound control, with dual compression adjustment likely.
Timeline
Earlier this year (2026): the fork was teased at Sea Otter Europe.
November 5, 2026: an article about the prototype suspension was published.
After the SEMA Show: the prototype bike heads to northern California for testing.
Health Landscape
Suspension design sits within the broader trail-riding equipment market, where inverted forks from Cane Creek and Fox have set recent benchmarks for weight and stiffness. KYB's entry brings a motorcycle-racing suspension specialist into that segment, with coil-spring designs competing against the air-sprung forks that dominate the category.
If you ride trails regularly, new suspension options can change how much your joints and back absorb on rough terrain, which is worth weighing against your own riding style. Any decision about riding gear or a physical activity routine is worth discussing with your doctor, especially if you have a joint or back condition.
The takeaway
Suspension technology affects how comfortably you can handle rough trails, so new designs are worth watching. Ask a bike shop or your physician about equipment that matches your fitness and any joint concerns before you buy.
What happens next
The prototype bike heads to northern California for testing after the SEMA Show, and the rear shock is still in development with changes possible before production.
