Front Fork Preload Adjuster Knob for Honda Africa Twin CRF1000L (19mm On-Bike Accessory)

Tool-free, stay-on front fork preload adjuster knobs designed specifically for the Honda Africa Twin CRF1000L (2016-2019).

These knobs press directly onto the factory 19mm hex preload nuts on top of the fork caps. Once installed, they remain on the bike as a permanent, functional cockpit accessory, allowing quick preload adjustments by hand without scratching the aluminum factory nuts or needing a wrench.

OVERVIEW:

Fitment: Honda Africa Twin CRF1000L (2016-2019) with 19mm front suspension preload hex nuts.

Function: Permanent stay-on adjuster knob / protective cosmetic cap.

Grip Design: Fluted/knurled outer surface for easy grip, even with riding gloves.

Installation: Press-fit onto the clean 19mm nut. For high-vibration off-road security, a small drop of silicone/RTV inside the hex socket ensures it stays securely in place.

PRINT SETTINGS & MATERIAL:

Filament: PETG, ASA, or ABS (Do not use PLA due to sun/UV exposure and radiator/engine heat).

Walls / Perimeters: 4 to 6 walls (Essential for torsional strength on the hex profile).

Infill: 40% - 50% (Gyroid or Cubic pattern).

Layer Height: 0.16mm - 0.20mm.

Supports: No supports needed.

Orientation: Print with the hex socket opening flat on the build plate.

FITMENT TIP:

If the inner hex fit is too tight due to printer shrinkage or elephant foot, use a slight negative value for XY Hole Compensation / Horizontal Expansion (-0.05mm to -0.1mm) in your slicer or lightly chamfer the bottom inner edge.
