• Core Advantages
| Stability | ★★★★★ | The DN-CTCC Model 2 takes a race‑grade, multi‑valve, rebound‑adjustable strut as its backbone and a five‑way independent, fully adjustable valve system as its soul. From compression to rebound, from low speeds to high speeds, and from standard operating conditions to extreme pressure relief, every stage can be tuned independently, enabling chassis engineers and advanced users to achieve truly “customized tuning on demand.” |

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
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. A 25‑step pressure‑relief valve provides a two‑stage compression curve, ensuring consistent damping performance regardless of ambient temperature or track conditions.
Precise track handling
The initial stage is supple, absorbing minor vibrations, while the final stage stiffens to handle extreme impacts—offering two distinct personalities in a single shock absorber. A twin-tube design paired with a high-pressure nitrogen reservoir delivers the most direct dynamic feedback from the steering wheel, giving you the edge in corners and putting every inch of the road firmly under your control.
 |  |  |  |
5 independent adjustable channels: Independent adjustment of high-speed/low-speed compression, high-speed/low-speed rebound, and high-speed pressure release.
| 25-stage pressure relief valve + two-stage slope compression: It actively relieves pressure when the compression force reaches a threshold, with a soft initial phase that absorbs minor vibrations and a firm final phase that withstands extreme impacts.
| Built-in high-pressure nitrogen cylinder: Suppresses fluid aeration and cavitation, ensuring stable damping.
| Fully customized adaptation: Both the upper and lower mounting brackets and the spring are customizable; overall length, stroke, and thread‑height are all adjustable.
