Hyperpro's RSC "Active" valving means that as steering speed increases, the damping automatically increases. Our "Active" technology is far beyond what any conventional aftermarket damper offers, and is a Hyperpro exclusive.

TRIPLE FUNCTION SEALS

Dust scraper and double (preloaded) oil seal, ensuring that dust cannot enter and oil cannot exit the damper at any time.

ADJUSTABLE DAMPING

Damping can be adjusted in a wide range, divided in 22 positions.

TWIN-TUBE DAMPING SYSTEM

This ensures that the clamping force of the tube-clamp does not obstruct the piston.

NITROGEN PRESSURIZED HEAT EXPANSION RESERVOIR

Gas pressure prevents the forming of air bubbles. Oil expansion due to temperature changes is compensated by the reservoir and does not influence damper performance.

ONE-PIECE PISTON ROD

Providing perfect alignment through the slide bearings and no excessive force on the piston.

LOW FRICTION DESIGN

8mm hard chromed piston rod with special surface treatment and special piston ring for smooth movement.

Active (RSC)
(Reactive Speed Control)

The HyperPro RSC is the only active valving damper available. As steering speed increases, the internal valving changes automatically to increase the damping effect. This results in a light, easy handling ride at low speeds while still keeping the heavy damping during extreme situations

non-Active (CSC)
(Constant Speed Control)

All of the great features of our top of the line RSC Active Valving Damper, without the active Valving. The CSC damper is a traditional Linear style damper, combining the quality and style you expect from HyperPro as a substantially lower cost.
