TUSK Dual Chamber Fork Cap Wrench Set for KYB Forks 49mm & 35mm — Hardened Steel, Zinc-Coated

TUSK's Dual Chamber Fork Cap Wrench is a two-piece, hardened-steel tool set engineered to remove and install both inner and outer caps on KYB-style dual-chamber motorcycle forks without marring the anodized finish.

Working on dual-chamber KYB forks demands the correct tooling to avoid damaging delicate cap surfaces and to hold the damping rod securely while loosening or tightening. This TUSK kit includes a 49 mm outer cap wrench with a slotted handle for rod control and a 35 mm inner cap wrench sized for the inner assembly. Zinc-coated, hardened steel construction keeps the set rugged for repeated home-shop or pro-shop use across a broad list of compatible models.

How does this wrench set protect fork cap finishes?

The wrenches are machined to precise dimensions so they sit flush against fork caps and distribute torque evenly, reducing the chance of slipping or gouging anodized surfaces. A zinc coating adds corrosion resistance while the hardened-steel profile resists deformation under load.

• Precision 49 mm and 35 mm fit prevents round-off and skidding.
• Zinc coating reduces rust and surface wear.
• Hardened steel resists bending under high torque.

Will this work on my motorcycle model?

The set is intended for KYB-style dual-chamber forks on many popular off-road and motocross models from mid‑2000s to recent years. Confirm your fork has dual chambers and matches the listed diameters before purchasing to ensure compatibility.

• Fits many Yamaha models including YZ125, YZ250, YZ250F, YZ450F, WR450F and others from 2005–2018 (model-dependent).
• Compatible with multiple Kawasaki and Honda dual‑chamber KYB forks on specified year ranges.
• Not for use on non-KYB or single-chamber forks without checking cap sizes first.

How does the slotted handle improve fork servicing?

The outer 49 mm wrench has an integrated slot designed to engage and hold the damping rod, preventing it from turning while you loosen or torque the cap. That feature makes one-person fork servicing easier and reduces the need for improvised holding tools that can damage components.

• Slot secures the damping rod for safer cap removal.
• Makes torque application more controlled and repeatable.
• Reduces risk of internal fork thread damage from slipping tools.

What maintenance and longevity can I expect from this tool set?

Because the wrenches are built from hardened steel with a protective zinc finish, they're intended to withstand frequent shop use and exposure to workshop conditions. Light care—cleaning after use and storing dry—will keep them functioning reliably for years.

• Hardened construction resists wear from repeated use.
• Zinc coating helps prevent surface rust in humid environments.
• Compact two-piece design stores easily in a toolbox or service kit.

Who is this for: The TUSK Dual Chamber Fork Cap Wrench set is aimed at motocross and off-road riders, DIY motorcycle mechanics, and professional technicians who service KYB-style dual-chamber forks. If you perform fork rebuilds or routine maintenance on compatible Yamaha, Kawasaki, or Honda models and want a precise, durable tool that minimizes cosmetic damage, this kit is designed to meet those needs.
