Park Tool LRT-2 Shimano STEPS lockring wrench — 54mm 16-notch, Black, heat-treated alloy for E6100/E7000/E8000

The Park Tool LRT-2 is a heavy-duty lockring wrench made specifically to remove and install Shimano STEPS E-bike motor lockrings with a 54mm diameter and 16 notches.

If you service Shimano STEPS e-bike motors (E6100, E7000, E8000 and compatible E9000 systems), the LRT-2 gives you the correct fit and leverage to work the motor-side lockring quickly, safely, and without damaging the aluminum or hardened steel ring. Built from heat-treated alloy and plated to resist corrosion, this Park Tool specialty wrench is shaped to engage the 16-notch profile so you can avoid improvised tools or risky hammering.

How does the LRT-2 fit Shimano STEPS lockrings?

The LRT-2 is engineered around the exact outer diameter and notch pattern used on Shimano STEPS motor lockrings. Its pocketed engagement matches the 16-notched profile and the 54mm outside diameter so every notch receives full contact for secure turning.

• Designed for 54mm outside diameter lockrings
• Matches 16-notch Shimano STEPS profiles
• Positive engagement reduces slipping and marring

What materials and finish keep the tool reliable?

Park Tool makes the LRT-2 from 4140 alloy steel that’s been heat-treated for strength and hardness, then plated to defend against rust in a workshop environment. That combination preserves teeth integrity and keeps the tool true under torque, so it won’t deform when you’re loosening a tight lockring.

• 4140 heat-treated steel core for durability
• Protective plating to minimize corrosion
• Precision-machined contacts for long life

How do I use the LRT-2 safely during motor service?

Use the LRT-2 with a compatible wrench or handle, seating it fully into the lockring’s notches before applying steady torque. Support the motor assembly, avoid sudden impacts, and back off immediately if you feel slippage; the tool is meant to reduce damage risk, not eliminate poor technique.

• Seat tool fully into the 16 notches before turning
• Use steady, controlled torque—avoid hammer strikes
• Combine with proper motor support and safety gloves

Who should choose the Park Tool LRT-2?

This tool is aimed at bike mechanics, e-bike technicians and serious home mechanics who maintain Shimano STEPS motors and want a purpose-built solution. If you work on E6100, E7000, E8000 or compatible E9000 drives and need a durable, accurate lockring wrench that prevents damage and speeds service, the LRT-2 fits that role perfectly.

In short: the Park Tool LRT-2 is a specialized, workshop-grade lockring tool that matches Shimano STEPS motor specifications, combines long-lasting materials with a corrosion-resistant finish, and helps you remove and install 54mm/16-notch lockrings with confidence and control.
