Steering head lock-ring tool

Option 1 - Stephen Brenton tools

Two tools are shown and recommended. Use one to hold one to tighten. There are 2 locknuts to deal with. See Guzzi Manual, Fig 101, items A and B. MG# 93601026 T

Stephen Brenton is kind enough to manufacture this tool. Contact him directly for price and availability.

Option 2 - Generic tools

I extracted this recommendation from Ralf Brinkmann off of the Yahoo! Loopframe_Guzzi news group.

Here are a few places where you can purchase the special hook wrenches that will permit you to easily tighten and loosen the two steering head stem nuts. You'll need two wrenches. The outside diameter of the steering head nuts is 1111111 mm.
