Wide inverted fork kit for Triumph Bobber and Speedmaster

This wide inverted fork kit has been developed for riders who want to give their Triumph Bobber or Bonneville Speedmaster a much stronger, more aggressive and more premium front-end stance.

Unlike a standard fork replacement, this version is designed as a true wide front-end conversion.

Thanks to its dedicated wide CNC-machined triple tree and Kayaba inverted fork legs, it allows the installation of a wider front wheel setup and can accommodate a front tire up to 180, depending on the selected wheel, tire profile and final installation.

The result is a more muscular and distinctive Bobber, with a wider visual presence, improved rigidity and a much more modern front-end feel.

• Wide front-end conversion
• More aggressive Bobber stance
• Compatible with wide front tire setups up to 180
• Improved front-end rigidity
• Premium custom motorcycle look

Why choose a wide Kayaba inverted fork?

This kit is not only about style. It transforms the front end of your Triumph Bobber or Speedmaster with a more technical, rigid and performance-oriented setup.

The inverted fork design improves front-end stiffness compared to the original fork layout, while the wide CNC-machined triple tree gives the bike a much stronger custom stance. Combined with high-quality Kayaba fork legs, the bike gains a more precise and confidence-inspiring front-end feel.

• Stronger front-end presence
• Improved steering precision
• Better rigidity under braking
• More stable and planted feel
• Ideal base for a high-end wide wheel build

Components included in the wide inverted fork kit

Wide CNC-machined triple tree

Designed by REM, the triple tree is fully CNC-machined from 6061 aluminum. Its wide configuration has been developed to create a stronger visual stance and to allow the installation of a wide front wheel setup.

This wide triple tree provides the rigidity required to fully exploit the potential of a modern inverted front end on a Triumph Bobber or Speedmaster.

Kayaba inverted fork legs

The fork legs are based on components from the Japanese manufacturer KAYABA, known for its high-quality suspension systems. The result is sharper steering, improved braking stability and a much more modern front-end feel compared to the stock setup.

Wide front tire compatibility

This wide version is designed for custom builds using a wider front wheel and tire setup. Depending on the selected wheel, tire profile, brake setup and final spacing, the kit can accommodate a front tire up to 180.

For best results, we recommend confirming the complete wheel, tire, brake disc and spacer configuration before ordering.

3 available colors

The fork tubes are available in silver, black or gold. Custom finishes are also available on request depending on your build style.

Performance brake kit available as an option

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

• High-performance radial calipers
• Matching master cylinder
• Clutch lever
• Brake lines

Once installed with the inverted fork, the braking improvement is immediate: more power, more precision and a much more confidence-inspiring feel both under hard riding and on the road.

Wheels available as an option

We also offer compatible wheels to build a complete and cohesive wide front-end setup:

• Spoked wheels
• Forged wheels

This allows you to create a fully customized front-end setup around the fork, depending on your desired style, from a premium performance look to a radical wide Bobber build.
