About the Honda TRX300 FourTrax
Keep the utility FourTrax model and the carburetor-kit year gaps clear.
The TRX300 FourTrax and TRX300FW FourTrax 4x4 are separately identified models in Honda repair references. The exact TRX300 code matters here: this is not an umbrella application for every ATV with 300 in its name. Record the complete identification before comparing parts with the four-wheel-drive FW or sport EX models.
Use the repair links to separate carburetor float work from rear brake or front master-cylinder service. For a carburetor rebuild, the kit below lists two distinct ranges: 1988–1991 and 1998–2000. The float and needle list 1988–2000, but their broader coverage does not fill the kit’s 1992–1997 gap. Identify the carburetor before deciding which pieces are needed.
Compare the actual applicationTRX300 part and year differences
Preserve the carburetor kit’s two separate ranges: 1988–1991 and 1998–2000. The selected rear brake shoes and float parts list 1988–2000, while the front master-cylinder kit lists 1988–1996. Select each component for its own application.

Identify the fitted equipmentTRX300 FourTrax identification and repair checks
- Read the complete ATV model code and verify that it is TRX300, without FW or EX, plus the model year.
- Identify the carburetor and compare the rebuild kit contents; do not fill the 1992–1997 application gap by assumption.
- For the rear shoes, compare the drum assembly, shoe dimensions, cam ends and spring arrangement.
- For front master-cylinder service, compare bore, piston and seal configuration with the fitted assembly.
