DescriptionThe whole story

Engineered from the same precision-machined components as its DDS Pro sibling, the K-Tech DDS Lite rear shock absorber delivers championship-grade suspension performance for the Kawasaki ZX-4RR at a compelling price point. Every CNC-machined part is built to K-Tech's exacting tolerances, and the unit is fully upgradeable to Pro specification should your ambitions grow.

Key Features

  • Four-way adjustability — compression, rebound, preload and ride-height — for a truly tailored chassis setup
  • 32-click compression damping adjustment for precise, repeatable control over bump absorption
  • 32-click rebound damping adjustment to fine-tune how quickly the shock recovers after a compression event
  • Manual spring preload adjustment for exact sag and weight-transfer calibration
  • Length adjustment to dial in chassis geometry and steering feel
  • CNC-machined aluminium components throughout for exceptional rigidity and long-term durability
  • DDS technology with integrated potentiometer mounting points for data-logging capability
  • Upgradeable from Lite to full Pro specification — hydraulic preload adjuster and bypass valve can be retrofitted
  • Wide range of spring rates available to suit rider weight and riding style

Build Quality and Materials

The DDS Lite shares its core architecture — including the damper body, internals and mounting hardware — with K-Tech's DDS Pro unit. The 35 mm RCU housing and 12 mm damper rod are machined from high-grade aluminium and hardened steel respectively, and the eye-type upper and lower mounts are finished to tight dimensional tolerances. The result is a shock that feels as precise on its hundredth lap as on its first.

Performance on Road and Track

The DDS (Dual Damping System) platform is the same foundation that K-Tech supplies to professional race teams. On the ZX-4RR's compact, high-revving chassis, the DDS Lite transforms mid-corner stability and edge-of-tyre feedback. Factory recommended settings — 12 compression clicks, 12 rebound clicks and 12 mm preload — provide an excellent baseline from which riders can explore the full 32-click range in either direction. The 55 mm stroke and 95 N operating force are optimised specifically for the ZX-4RR's suspension linkage ratio.
