Kid-friendly fit, grown-up performance
The XR1 Kids' is a durable, kid-friendly tire with the same reliable traction and performance as the grown-up versions. It rolls fast, features a versatile tread for a variety of trail conditions, and keeps weight down so little rippers can quickly gain speed and keep momentum through corners and up hills.
