KYB Shock Bladder Ø40 mm for YAMAHA YZ 65, YZ 80, YZ 85 and KAWASAKI KX 85, KX 100 1993-2026

The KYB Ø40 mm KYB-2001000 shock bladder is designed for YAMAHA YZ 65, YZ 80, YZ 85 and KAWASAKI KX 85, KX 100 from 1993 to 2026. The bladder sits in the shock reservoir and separates the oil from the pressurised nitrogen. Over time, the rubber hardens or cracks: the nitrogen mixes with the oil and the damping becomes inconsistent.

Specifications

• Brand: KYB
• Manufacturer part number: KYB-2001000
• Diameter: 40 mm, length: 88 mm

When to replace it?

• Damping that is inconsistent or that fades as the shock heats up.
• Nitrogen pressure that drops between checks.
• Bladder hardened, deformed or cracked when opened.

Replace the bladder at every full shock service. Check its dimensions (diameter and length in the name): it has to match the reservoir.

Fitting tips

1. Release the nitrogen from the reservoir following the manual before opening anything.
2. Remove the reservoir cap and the old bladder, and clean the reservoir.
3. Fit the new bladder, bleed the air from the shock and recharge the nitrogen to the manual's pressure.

Frequently asked questions

Can I top it up with air?
No: a shock is charged with nitrogen, a dry gas that stays stable as the temperature changes. Without the equipment, leave the recharge to a specialist.
