80/100 -21 51M TT NHS X31

Bridgestone X31 (NHS)
The Bridgestone X31 is a motocross tyre created for riders who want strong traction, controlled handling and improved drive in intermediate terrain. Its compound is engineered for reliable grip and predictable flex, giving confident acceleration and braking on mixed soil, hard packed dirt and loose surfaces. The tread pattern uses advanced block positioning and updated shoulder design to increase bite while maintaining stability when the terrain becomes rutted or uneven.

The construction provides race level feedback with a balance of rigidity and compliance, supporting aggressive riding, precise control at lean and consistent performance throughout the moto. The X31 is an NHS tyre, meaning it is designed for competition use and is not approved for road riding.
