Performance technology products
Multi‑damping shock absorbers: the key to clinching victory on the racetrack.
Technical Highlights
Through in-house manufacturing and rigorous quality-control processes, we strive to achieve tighter tolerances and greater product consistency. This enables vehicles to deliver crisp road feedback and stable traction—our starting point for both products and services.
To ensure optimal performance on specific vehicle models, we conduct necessary measurements and make appropriate adjustments based on model‑specific data prior to delivery, enabling the upgraded components to deliver their full potential.
Our product lineup covers off-road motorcycles, dirt bikes, electric off-road motorcycles, and motocross bikes.
Our internal R&D efforts involve cross‑disciplinary development; these cross‑functional experiences and technological expertise broaden our perspective and provide valuable insights, which we leverage to drive continuous product improvement.
Pure shock-absorbing force
The adaptive damper delivers an impeccable balance of comfort, traction, and handling. With adjustable compression and rebound settings, you can fine-tune every drive to suit your personal preferences. Its reverse‑flow design enhances response speed and heat dissipation, while the piston rod is effectively protected—regardless of ambient temperature or terrain.
Ultimate off-road road feel
Dynamic feedback on every turn. Optionally equipped with ART—Advanced Roll‑Control Technology—this system intelligently suppresses body roll and pitch in corners, delivering an exhilarating driving experience whether you’re tackling extreme jumps or carving through high‑speed bends, empowering you to push the limits without fear of performance fade.

Single-tube multi-valve damping: Single-tube multi-valve technology ensures efficient oil cooling and stable damping, while the coilover height is adjustable, balancing a low center of gravity with high structural strength.
|
Inverted structure: The inverted‑type structure enhances response speed and heat dissipation, while the piston rod is effectively protected.
|
Optional ART anti-roll system with 5–6-way adjustable basic damping: It knows cornering, braking, and acceleration; the automatic ART system intelligently increases compression damping, while low-speed rebound and low-speed compression are independently adjustable. |
Dual protection: secondary piston plus hydraulic buffer. The secondary piston delivers progressive damping in the latter portion of its stroke, while bidirectional hydraulic bump stops at the end smoothly dissipate extreme energy.
