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
Experience‑based dampers deliver 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. The ART anti‑roll and rapid rebound systems work in tandem to ensure a consistent damping feel, whether you’re tackling desert heat or frigid snow.
Ultimate off-road road feel
Sturdy yet resilient support delivers the most direct dynamic feedback from the steering wheel. With a forged CNC‑machined precision body and aerospace‑grade materials, whether tackling extreme jumps or high‑speed corners, we give you the most intense sensations, boosting your confidence and letting you push harder—without fatigue.
HP.2 Technical Highlights
 |  |  |  |
Single-tube multi-valve damping + race‑grade chassis: The single-tube, multi-valve design ensures stable heat dissipation and damping, with adjustable coil‑over height, and is available in aluminum alloy or steel alloy.
|
FRS Fixed Rapid-Rebound System: After clearing the obstacle, the wheel automatically accelerates and rebounds to its full stroke, reserving travel for the next impact.
|
5-7 Adjustable to Precise Damping: High-speed/low-speed rebound and high-speed/low-speed compression
|
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 absorb peak energy.
