YSS HYD Z1 Cartridge Kit (Manufacturer Ref: CO208-710TRC-03) — a hydraulic cartridge designed for riders looking to fine-tune their suspension behavior on the road. Designed for roadster use and compatible with the listed models (notably YAMAHA R7 2023‑2025), this kit offers precise adjustments and an enhanced mechanical feel.
- Compression Adjustment: hydraulic needle providing control over the oil flow between the tube and the gas reservoir, with a range of adjustment over 25 positions to dial in firmness at low speeds.
- Rebound Adjustment: knob with audible clicks at each notch to adjust the return oil flow and control rebound after compression.
- Threaded Preload: a threaded ring to compress the spring, which can be locked in place once the desired position is reached.
- Specification: length 710 mm — product not homologated.
This cartridge kit emphasizes modularity: each adjustment is accessible and designed to provide feedback to the rider without complicating the installation. Ideal for those looking to refine the spring rate and hydraulic sensitivity for road use while maintaining a simple and reproducible setup.
