Honda CB500/CB550 USD Fork Conversion Triple Tree Kit

Bring modern front suspension to a classic Honda with the MessnerMoto Honda CB500/CB550 USD Fork Conversion Kit.

Designed for Honda CB500 and CB550 motorcycles, this CNC triple tree kit allows you to install modern USD forks while maintaining a clean, purpose-built front end.

Unlike conversion kits designed around one specific donor motorcycle, the MessnerMoto system is configured around the USD forks you choose to use. This gives you far more freedom when selecting suspension, brakes, wheels and other components for your Honda café racer, restomod or custom build.

Honda CB500 & CB550 Compatibility

The conversion kit is available for classic Honda models including:

• Honda CB500
• Honda CB550
• Honda CB500 K
• Honda CB550 K
• Honda CB500 F
• Honda CB550 F

Each conversion is configured around the motorcycle and front-end combination selected for the build.

Built Around Your Choice of USD Forks

You are not restricted to one particular donor front end.

The triple trees can be configured for a wide range of modern USD forks, giving you the freedom to choose the suspension setup that suits your project.

Popular options include:

• Suzuki GSX-R USD forks
• Honda CBR USD forks
• Yamaha R1 USD forks
• Yamaha R6 USD forks
• Kawasaki ZX USD forks
• Ducati USD forks
• Triumph USD forks
• Showa USD forks
• Öhlins USD forks

Other USD fork configurations can also be accommodated.

After ordering, we confirm the relevant information about your donor forks so the triple trees can be produced for your specific front-end configuration.

This makes the kit suitable for everything from straightforward Honda CB550 USD fork conversions to highly individual custom motorcycle projects.

Complete CNC Triple Tree Kit

The Honda CB500/CB550 USD fork conversion kit includes the essential triple-tree components required to adapt a modern front end to the classic Honda chassis.

Included in the kit:

• CNC-machined upper triple tree
• CNC-machined lower triple tree
• Custom Honda conversion stem
• Aluminum top nut
• Adjustable steering stops

The components are designed together as a complete conversion system rather than as individual universal parts.

Multiple Triple Tree Offset Options

Front-end geometry is an important part of any fork conversion.

For this reason, the MessnerMoto Honda CB500/CB550 triple trees are available with several offset options:

30 mm / 35 mm / 40 mm / 45 mm / 50 mm / 55 mm / 60 mm

This allows the triple tree configuration to be better matched to different forks, wheels and custom motorcycle setups.

40 mm is our general-purpose choice for many conversions, but the appropriate offset depends on the complete motorcycle setup.

Fork length, wheel and tire dimensions, ride height and other geometry changes should all be considered when planning a custom front end.

CNC-Machined 6061-T6 Aluminum

The upper and lower triple trees are precision CNC-machined from 6061-T6 aluminum. The existing Honda kit already uses this material and offers both black and silver anodized finishes. MessnerMoto

After machining, the components are finished to create the clean, technical appearance characteristic of MessnerMoto parts.

Two finishes are available:

• Hard Anodized Black
• Silver Anodized

The minimalist design works particularly well on Honda CB café racers and restomods where the front end is visually exposed and every component becomes part of the overall motorcycle design.

Modern Suspension for a Classic Honda CB

A USD fork conversion can completely transform the front end of a classic Honda CB500 or CB550.

Modern forks give builders access to a much wider range of suspension and brake configurations while creating the compact, performance-oriented front-end proportions commonly seen on modern café racers and restomods.

The MessnerMoto conversion kit provides the connection between those modern components and the classic Honda chassis.

Whether you’re building a clean CB500 restomod or a heavily modified Honda CB550 café racer, the system gives you the flexibility to build the front end around the components you actually want to use.

Build a Complete Honda CB USD Front End

The triple tree kit can be combined with other MessnerMoto components to create a complete custom front-end setup.

Depending on your build, compatible components can include:

• CNC clip-on handlebars
• CNC motorcycle mirrors
• CNC LED handlebar switches
• CNC motorcycle throttle
• Radial brake and clutch master cylinders
• CNC headlight components

Fork diameter determines which clip-ons and other fork-mounted components are appropriate, so these can be selected around your particular USD fork setup.

Ordering Your Custom Fork Configuration

Your USD Fork Information

Because this kit is configured around your chosen front end, we need to know which USD forks you intend to use.

After your order is placed, we will confirm the necessary fork information before production.

Depending on the conversion, this may include:

• Fork manufacturer
• Donor motorcycle
• Model
• Model year
• Fork dimensions
• Selected triple tree offset

This allows us to configure the triple trees for your particular Honda CB500/CB550 and USD fork combination.

If you’re planning an unusual front-end conversion, contact us to discuss the setup.
