Most manufacturers will use the most flexible and cheapest dampers to reduce costs but also gain a general driving condition of the road, but to be used to cope with intense driving, these shock absorbers can not perform competently, IASATI launching a new shock absorber-SS version, features a combination of the advantages of RS shock absorber and Hi-Low Kit designed but unadjustable tube. For comfort, the damping should keep certain flexibility to allow the shock absorber to absorber the vibration from the road therefore increasing control stability and riding comfort, The spring design possesses the comfort under low speeds and stability under high speed, and tracking in corner.

Double tube structure: high speed series shock absorbers all possess single tube structure for higher radiation and inhibit oil viscosity changing, and minimize damping character changing.
