New & Improved Design!

Our 65-5331 Fork Tube Nuts (Specials) are back with the same great look but now feature an improved design and enhanced functionality.


Perfect Fit
These nuts retain the original thread and size, ensuring compatibility with your motorcycle—no modifications or adjustments required. Each one is screwed into 
original fork legs as well as checked using thread gauges, during manufacturing and again before dispatch.


Easy Installation: They screw directly into the top of the fork tubes.

Premium Features:

  • Durable Construction: Each pair is crafted from solid stainless steel for exceptional strength and longevity.
  • Premium Polished Finish - We take pride in our parts and ensure they look their absolute best. Each of our Specials is hand-polished to a stunning finish before dispatch. (See photos)
  • Removable Bronze Plug: The bronze center makes topping up or changing fork oil effortless.
    For models with clock brackets, you can service the fork oil without disturbing the brackets, reducing the risk of paint scratches.
  • Secondary Damper System Compatibility: Our revised design supports CPC's secondary damper system, which screws directly into the underside of the nuts. (Secondary damper system sold separately.)
