TUSK Dual-Chamber Fork Cap Wrench 49/35mm Two-Piece Set — Hardened Steel, Slotted Handle

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

Servicing dual‑chamber KYB forks requires the correct tools to avoid damaging anodized caps and to control the damping rod while you work. The TUSK kit brings a precision fit and durable construction so both professional mechanics and home riders can change spring preload, service seals, or rebuild forks with confidence. Compatible with many popular off‑road and motocross models, this set simplifies cap removal and helps protect visible fork surfaces.

Which fork models and years will this wrench fit?

Designed for KYB-style dual-chamber forks, the TUSK set matches the common inner and outer cap sizes used across several Honda, Kawasaki, and Yamaha models. Check your fork cap diameters and the manufacturer’s service manual if you’re unsure, but the kit covers many YZ and WR models from mid-2000s through mid-2020s.

• Fits many Yamaha models including YZ250/250F/450F and WR450F across 2005–2018 ranges.
• Compatible with Honda CRF450R (2009–2016) and Kawasaki KLX/KX450R/KX450F model years listed.
• Includes both a 49 mm outer cap tool and a 35 mm inner cap tool to match dual-chamber dimensions.

How does the wrench protect fork caps and make removal easier?

The tools are machined for an accurate seating on cap flats to reduce slipping, and the zinc-coated, hardened-steel finish resists wear while minimizing surface marring. The outer wrench features a slotted handle that lets you hold the damping rod steady, preventing rotation and allowing controlled torque when loosening or tightening caps.

• Precision-cut sockets reduce rounding or slipping on anodized cap edges.
• Slotted outer handle secures the damping rod for safer cap removal.
• Zinc coating and hardened steel increase longevity and limit surface damage.

What does the two-piece set include and how will it speed up fork service?

The kit contains a 49 mm outer cap wrench with an integrated slotted handle and a 35 mm inner cap wrench sized for the inner assembly. Having both sizes on hand eliminates makeshift solutions, reduces time spent searching for the correct tool, and lowers risk of cosmetic or mechanical damage during disassembly and reassembly.

• 49 mm outer cap wrench with slotted handle for damping rod access.
• 35 mm inner cap wrench for the inner chamber cap.
• Hardened steel construction for repeated professional or at-home use.

Can I use this wrench for professional shop work and at-home maintenance?

Yes. The durability and accurate fit make the set suitable for both daily shop use and occasional home servicing. It’s compact enough to store in a toolbox yet stout enough to withstand repeated torqueing during rebuilds, seal replacements, or routine inspections.

• Sturdy enough for frequent professional use.
• Compact, portable set ideal for home mechanics and trackside repairs.
• Helps maintain fork appearance and function by avoiding improvised tools.

Who is this for: The TUSK Dual Chamber Fork Cap Wrench set is built for motocross and off‑road riders, home mechanics, and professional technicians who work on KYB-style dual‑chamber forks and want a reliable, non-marring solution. If you service YZ, WR, CRF, KX, or KLX forks listed in the compatibility range and need the correct inner and outer cap sizes, this kit saves time and protects the fork finish during maintenance.
