K-Tech DDS Cartridge Kit – Aprilia RSV4

The K-Tech DDS Cartridge Kits is the same kit found on today’s race bikes in BSK, MotoAmerica and Isle of Man TT. Designed to replace your factory fork internals, the DDS cartridge provides rebound, compression and preload control. The result is a complete transformation of your front end to give maximum feel and control.

Includes 3 sets of springs and tools.

The K-Tech DDS (Direct Damping System) cartridge kit is designed for high end racing applications.  The DDS cartridge replaces OEM internals, because of this the front end is much more stable and provides better feel. The K-Tech DDS cartridge pressurized damping system uses 20mm displacing pistons, this creates high flow of oil through 31mm control valves. This is the key that gives precise damping control. The patent design eliminates cavitation, therefore making the system very stable under extreme conditions.  The damping circuits work independently, this improves the dynamics and response time.  Spring force provides pressure for the system, as a result the system is much more stable under all working temperatures.
