Rim width is the maker's recommended width for that size. Specs are from Dunlop's Geomax MX54 size chart.
How to choose
- Match the rim diameter first: full-size motocross bikes run a 21 front and 19 rear, enduro bikes 21/18, big-wheel 85 and 105cc bikes 19/16, small-wheel minis 17/14.
- Then the width: wider rear rims (2.50 and up) suit the 110 and 120 widths.
Add a tube sized to the tire (the Tube column lists ours) and rim locks if you run low pressure.
