About the Honda TRX300EX
Use the complete TRX300EX code for the sport ATV and check every component’s year range.
Honda’s 2005 TRX300EX specifications identify a 282 cc air-cooled four-stroke single. The EX suffix is essential in a parts search because the TRX300 name also appears on separate Honda utility ATVs. Similar engine-size names are not a reliable guide to carburetor, brake or electrical compatibility.
A TRX300EX carburetor repair may call for a rebuild kit, a float or a float needle, depending on the condition of the fitted carburetor. Their applications differ: the kit below lists 1993–2006, while the float parts list 1993–2001. Brake pads and the regulator/rectifier have separate end years too, making the ATV’s year an essential part of each selection.
