About the Honda CR500R

Choose gasket sets, individual clutch plates, rear pads and later fork seals around the work your CR500R needs.

Honda Motorcycle Logo

Maintaining a CR500R means identifying the assemblies on the motorcycle today. Engine, clutch and suspension parts each have their own service ranges, and a replacement engine or front end may differ from the frame’s model year. Keep component markings and donor details with your repair notes.

Build an engine or chassis repair order

For engine work, compare the gasket set’s supplied pieces with the joints being opened. For clutch service, establish the plate type, condition and quantity before ordering individual plates. A fork-seal job needs all three seal dimensions and a separate look at dust seals and bushings; rear-pad replacement starts with the fitted caliper and old pad outline.

The linked products cover 1989–2001 engine gaskets, 1990–2001 clutch plates, 1996–2001 fork seals and 1987–2001 rear pads. For early cooling differences, front-pad options and earlier fork-seal sizes, use the Honda CR500 model and year guide. Other motocross models are grouped in Honda CR parts.

Model and year comparisonCR500R parts differences

Engine versus clutch

1989 is included in one range

The engine gasket set lists 1989–2001. The clutch plate lists 1990–2001, so its application cannot be extended back to 1989 from the gasket range.

Later fork service

1996–2001 oil-seal application

The later oil-seal set measures 46 × 58 × 9.5 mm. Earlier CR500R forks have separate product pages; measure the fitted assembly rather than choosing by a familiar model name.

Prepare for the repairIdentify your CR500R components

  1. Confirm the model year and compare frame and engine markings with the documentation. Treat a replacement engine as a separate identification task.
  2. Compare each gasket set’s contents with the repair scope. For clutch plates, confirm type, thickness, tab pattern and quantity.
  3. Measure the old fork seal and identify the fitted rear caliper. Preserve any application gaps or end years in the product page.

Honda CR500R parts questions

What years does the CR500R engine gasket set fit?
The linked engine gasket set lists Honda CR500R 1989–2001. Compare its supplied gaskets with the engine and the joints being opened. The product description establishes the set contents; additional seals may be needed for the planned work.
How are CR500R clutch plates sold?
The linked clutch plate is sold individually and lists CR500R 1990–2001. Confirm the plate type and quantity required from the clutch condition and service information. Its application excludes 1989, even though the linked gasket set includes that year.
What size fork seals fit a 1996–2001 CR500R?
The linked set contains two oil seals measuring 46 × 58 × 9.5 mm and lists CR500R 1996–2001. Match the actual forks and seal style. Dust seals and bushings are separate components to inspect for the repair.
Where can I find early CR500R fork seals and front brake pads?
The Honda CR500 family guide compares the earlier 43 × 54 × 11 mm and 45 × 57 × 11 mm fork-seal sets, plus front pads for 1984–1986 and 1987–1994. Match the model year and fitted assembly before choosing one of those applications.
