Why choose an inverted Kayaba fork for your Harley-Davidson Sportster?

This kit is much more than a cosmetic upgrade. It is a true front-end transformation for the Sportster platform. With its modern inverted design, rigid CNC-machined triple clamp, and premium Kayaba fork legs, the bike becomes more precise, more stable, more confidence-inspiring, and far more distinctive visually.

• Improved front-end precision
• Sharper braking stability
• Stronger road feel
• More premium and aggressive stance
• A complete change in the character of the motorcycle

The different elements that compose the inverted fork kit

Triple clamp

Designed by REM, the triple clamp is entirely CNC machined from 6061 aluminum. It provides the rigidity and precision needed to fully exploit the performance of the inverted Kayaba front end.

Kayaba fork legs

The fork legs are based on components from the renowned Japanese manufacturer KAYABA. This setup brings a much more modern front-end feel compared to the original Sportster fork and dramatically upgrades the motorcycle’s handling and visual impact.

2 available lengths

The 33inch / 840 mm version is ideal for a club style or street scrambler build.
The 29.9inch / 760 mm version is ideal for a sport custom, roadster, or cafe racer build.

Length available: 29.9 inch / 760 mm or 33inch / 840 mm.
Tube diameter: 43 mm.
Travel: 120 mm for the 29.9 inch / 760 mm version and 150 mm for the 3inch / 840 mm version.

3 triple clamp widths available

To ensure perfect fitment depending on the wheel you use, we offer this inverted fork kit in three different triple clamp widths.

The required width depends on the hub width, measured disc mount to disc mount.

• 112 mm for a standard Sportster wheel
• 141 mm for a Forty-Eight wheel for example
• 161 mm for wider Harley-Davidson wheels

This allows us to match the fork kit perfectly to your front wheel setup for correct spacing, proper alignment, and a cleaner overall fit.

3 available colors

The fork tubes are available in silver, black, or gold. Custom finishes are also possible on request. The inner tubes can also be customized in a different finish.

The 29.9" black version :

Optional performance brake kit available

To fully match the potential of the inverted fork, we also offer an optional performance brake kit.

• Performance Radial calipers
• Matching master cylinder
• Clutch lever
• Brake lines

Once paired with the inverted front end, the braking performance has nothing to do with the stock Sportster feel. The result is a much stronger, more precise, and more confidence-inspiring front brake setup.

Optional wheels available

We also offer matching wheels to complete the build and create a fully coherent front end:

• Spoked wheels
• Forged aluminum wheels

This allows you to build a complete front-end package around the fork, depending on the style and performance level you want.

What is included in the fork kit

• Triple clamp
• Steering stem
