DescriptionThe whole story▼
Engineered by K-Tech Suspension — one of the most respected names in precision suspension engineering — this service kit is the definitive rebuild solution for the rear shock absorber fitted to the Aprilia RSV4 family. Every component is manufactured to match or exceed original K-Tech tolerances, restoring the crisp, confidence-inspiring damping that defines these Italian superbikes and keeping them performing exactly as the factory intended, lap after lap.
Key Features
- Complete rebuild kit containing every seal, bushing and fastener required for a professional shock absorber overhaul
- Oil seal provides a precision-tight barrier against fluid loss and pressure drop
- Dust seal shields the piston rod from road contamination and abrasive particles
- Piston rod bushing ensures accurate rod guidance and lateral stability throughout the stroke
- Comprehensive O-ring set delivers reliable sealing across all internal interfaces
- New piston rod locking nut included for safe, correct reassembly torque retention
- All parts match or surpass OEM K-Tech specification for long-service reliability
Design, Finish and Heritage
K-Tech Suspension has built its reputation supplying suspension components to World Superbike and BSB teams, and that motorsport heritage flows directly into every service kit bearing the K-Tech name. The internal dimensions — 42.00 mm inner diameter and 14.00 mm outer diameter — are held to exacting tolerances, reflecting the same manufacturing discipline applied to K-Tech's race-homologated components. This is not a generic aftermarket rebuild pack; it is a purpose-designed kit matched precisely to the shock absorber architecture of the RSV4 platform.
Performance and Longevity
Over time, shock absorber seals degrade, oil migrates past worn surfaces, and the precise damping characteristics that make the RSV4 so rewarding to ride begin to erode. Rebuilding with this kit — part number 205-200-030 — arrests that deterioration at source. Fresh seals eliminate fluid weepage, a new bushing restores rod geometry, and a correctly torqued locking nut ensures structural integrity. The result is a shock that behaves as it did when new, whether you are threading through traffic or chasing lap times at a circuit day.
Fitment and Compatibility
This service kit is designed for the following models:
- Aprilia RSV4 1000 RF (2017–2019)
- Aprilia RSV4 1100 Factory (2019–2026)
- Aprilia Tuono V4 1100 Factory (2019–2020) — original TTX36 42/14 specification
Installation Note
Shock absorber servicing requires specialist tooling and technical knowledge. For optimum safety and to ensure the shock is rebuilt to the correct performance standard, K-Tech recommends installation and servicing by an authorised K-Tech Service Centre.
