Moose Offroad Hard Shock Absorber Bladder - Parts (manufacturer's ref: 211-900-100)

Replacement bladder designed for rear mounts equipped with an enlarged reservoir. Designed to fit the latest WP XACT 5057 2023 shock absorbers with an expanded reservoir, this black bladder is sold individually and matches the original specifications for a simple and clean replacement.

• Type: Shock absorber bladder
• Position: Rear
• Outer diameter: 60.00 mm (2.36")
• Colour / finish: Black
• Unit: Sold individually

The bladder is designed to reduce internal friction between gas and oil and to increase the useful gas volume in the reservoir — a sought-after configuration for enduro/cross/supermoto rear setups. As an original replacement, it restores consistent shock absorber behaviour when the geometry and reservoir are those of the relevant models. For correct installation, use tool 213-900-085.

Compatible with frames equipped with the WP XACT 5057 (2023 version with enlarged reservoir) and commonly found on modern 450 models (Husqvarna FE 450 Heritage, GasGas MC 450 F, KTM SX‑F 450). Check your shock absorber reference before ordering.
