The Pirelli MT 21 RALLYCROSS R 120/80R18 62R is an off‑road motorcycle tyre crafted for rallycross and mixed terrain competition where traction and durability are essential. It is aimed at riders who need aggressive bite on loose surfaces while retaining controllable behaviour on harder ground. The blocky tread pattern produces strong water evacuation and an enlarged contact patch for improved traction in wet, muddy conditions. Cornering stability is delivered through the tread geometry and reinforced shoulder blocks that resist deformation under load. Driving comfort is considered insofar as the carcass absorbs impacts without sacrificing feedback.

Built with a robust carcass and reinforced elements, the tyre supports repeated impacts and sharp direction changes typical of rallycross stages. The compound and tread design promote even wear under abrasive conditions and sustain consistent performance over race distances. The profile enhances steering response for quick line changes and better control at speed. It is engineered to cope with high loads while maintaining reliable traction.

For competitors this tyre offers the aggressive grip and durability required for off‑road racing. Its construction balances longevity with the immediate bite needed for fast exits and stable braking on mixed surfaces.
