About this part

The Macfox outer tire is a 20 x 4 in fat tire with a knobby, all-surface tread, sold as a single tire rather than a pair. It fits the X1S and X2, the two models built around this tire size.

The tread keeps grip on dry dirt, mud, asphalt, and sand without specializing in any one surface. The X2 Pro runs wider tires, 4.5 in front and 5.0 in rear, so this is not the right tire for that model.

The Part

The same part your bike left the factory with

A genuine vendor part, not a copy. It fits the factory mounts and connectors, so nothing else on the bike has to change.

Directly replaces the factory 20 x 4 in tire on the X1S and X2.
