Product Description

Brief Overview

This flat, triple-opening fork cap wrench addresses a critical gap in fork service tooling. The 24/32/41mm configuration targets Big Piston Fork (BPF) applications, particularly 09–10 GSXR1000 and ZX-6R models, where factory fork caps require precise engagement. The stamped steel construction with chamfered hex openings minimizes cam-out during high-torque cap removal and installation—a common pain point in motorcycle suspension work. For shops handling modern sportbike suspension, this tool pairs naturally with split-sleeve fork seal drivers and larger capacity cap wrenches to build a complete fork service kit.

Key Features

  • Three Hex Sizes in One Tool: 24mm, 32mm, and 41mm openings eliminate the need for multiple wrenches during fork cap service
  • Flat Plate Design: Streamlined profile allows access in tight fork crown spaces and reduces tool inventory footprint
  • S45C Steel Construction: Carbon steel body provides the rigidity needed for high-torque cap removal without deflection
  • Corrosion-Resistant Zinc Plating: Yellow/gold chromate finish protects against shop moisture and extends service life
  • Chamfered Hex Openings: Beveled internal corners reduce rounding risk on worn or soft fork caps
  • Stamped, Single-Piece Construction: No moving parts or adjustments—simple, durable, and field-reliable

Business Advantages for Resellers

Targeted OEM Fit: This wrench directly addresses a specific, documented need in the sportbike suspension market (GSXR, ZX platforms). Shops servicing these models will recognize the value immediately.

Kit Builder Opportunity: Pair this wrench with fork seal installation tools to create a bundled fork service package. High perceived value + margin stacking.

Low Holding Cost: Flat plate design stores efficiently, reducing shelf space consumption compared to multi-piece fork cap socket sets.

Repeat Sales Entry Point: Shops that buy this tool for one platform often expand to other sportbike brands requiring similar-sized caps.

Why This Tool Matters

Fork cap service is high-margin work in modern motorcycle shops. Standard open-end wrenches slip on oversized caps; adjustable wrenches round corners. This wrench engages the full hex face, distributing force across the cap and reducing damage risk—which translates to faster, more professional service delivery for your customers.

The 24/32/41mm progression is not arbitrary; it covers the critical range for mid-size and large-displacement sportbike forks. Stock this wrench if you serve the motorcycle suspension repair segment.
