About the Honda GB500

Carburetor and front-brake service for Honda’s GB500 Tourist Trophy single.

Honda Motorcycle Logo

The Honda GB500 Tourist Trophy, also identified as GB500TT, pairs an air-cooled four-stroke single with styling inspired by 1960s British road-racing motorcycles. Honda announced it in Japan in 1985; the repair parts featured here use separate GB500 1989–1990 applications.

Locate the fault before choosing the service part

A carburetor float, caliper seal kit and reservoir diaphragm repair three different assemblies. Check the float and fuel valve for fuel-level trouble. For a brake-fluid leak, identify whether it comes from the caliper or reservoir before selecting seals or a diaphragm.

Know your model before choosing partsHonda GB500 repair checkpoints

Use the complete model, year and fitted assembly. Each product has its own application and package contents.

Model history and market years

The Japanese GB500TT introduction predates the featured 1989–1990 parts applications. Use the product’s listed years for ordering.

Caliper versus reservoir

Caliper seals work at the brake caliper. A reservoir diaphragm is under the master-cylinder reservoir cover; it is not a caliper or master-cylinder piston repair kit.

Carburetor float versus valve

The float controls fuel level through the float valve. Replacing one does not establish that the other is serviceable or included.

Identify your model before orderingHonda GB500 identification checklist

Use the identification on your machine and the component being repaired.

  1. Read GB500, year and market identification; record replacement engine markings separately.
  2. Identify the carburetor and compare the original float construction.
  3. Record front-caliper and master-cylinder details before selecting brake seals or a reservoir diaphragm.

Honda GB500 parts questions

Do the featured GB500 parts cover the 1985 Japanese model?
The linked float, caliper kit and reservoir diaphragm list GB500 1989–1990. Honda’s 1985 Japanese introduction is model history, not confirmation that these parts fit that earlier market version.
Is the GB500 reservoir diaphragm a master-cylinder rebuild kit?
No. It is the flexible part beneath the reservoir cover. It does not replace the master-cylinder piston seals or the seals inside the brake caliper.
Will a new GB500 carburetor float fix every fuel leak?
No. Identify the leak and inspect the float, valve and sealing parts separately. Match the fitted carburetor and compare the product contents before deciding which repair parts are needed.
Should GB500 brake parts be ordered by year alone?
Use the year and the fitted assembly. Replacement calipers or handlebar controls can change the required seals, diaphragm or other repair components.
