Description

Twin-Chamber Cap Wrench, 46/50mm – Motorcycle Engine Service Tool

Brief Overview

This is a specialized dual-capacity cap wrench designed for precision motorcycle engine service work. It addresses a specific professional need: removing compression valve assemblies on high-performance Honda and Suzuki dirt bikes and sport models. If your shop regularly services these platforms, this tool eliminates the need to stock two separate wrenches. Pair it with offset ratchet wrenches for glow plug service to build a complete motorcycle engine maintenance toolkit.

Key Features

  • Dual-capacity design: 46mm and 50mm octagonal cap openings in a single tool

  • Zinc-plated finish: Corrosion-resistant yellow/gold chromate plating for workshop durability
  • Flat profile: Slim design allows access in confined engine spaces
  • Rectangular handle cutouts: Grip-friendly design reduces hand fatigue during prolonged use

Why Your Customers Need This

Mechanics servicing high-performance Honda and Suzuki dirt bikes face a critical bottleneck: accessing compression valve assemblies requires precise-fit cap wrenches. Off-spec tools risk stripping the soft aluminum caps, leading to costly engine repairs. This wrench fits those specific assemblies reliably, reducing rework and building shop reputation in the motorcycle service segment.

Stock this tool when building a motorcycle engine service line, or offer it as a specialty add-on to mechanics who already work on these platforms.
