The Pirelli MT 21 RALLYCROSS 140/80R18 70R is an off‑road motorcycle tyre tailored for mixed terrain rally and enduro use, suitable for riders tackling gravel, mud and asphalt sections. It is built to offer traction and endurance across variable surfaces while supporting typical off‑road loads. The aggressive tread geometry prioritises bite in loose terrain while preserving stability on harder surfaces.

Deep, widely spaced blocks and reinforced shoulders deliver robust grip and efficient self‑cleaning to maintain traction in challenging conditions. The compound and carcass design aim to keep a reliable contact patch under lateral stress, improving cornering stability and consistent steering response. The tyre also provides good braking behaviour on mixed surfaces through optimised block edges.

For the rider this means improved control during rapid direction changes and dependable braking performance on softer ground. Enhanced structural strength supports higher load capacity and resistance to impacts, while the tread layout favours predictable wear and extended mileage even when used intensively off‑road.
