Enduro tyre PIRELLI SCORPION RALLY (F) Wide knobs 90/90-21 M/C 54R TL M+S front

PIRELLI offers this enduro tyre. In enduro, a single ride strings together rocks, roots, mud, sand and sometimes road: the tyre has to grip everywhere and stand up to impacts.

Why choose an enduro tyre?

The benefits:

• Versatile grip to link rocks, roots and mud on the same ride, with a carcass designed to take impacts.
• Depending on the model, road approved: you can ride legally on the road with a registered bike.
• Mousse or tube: a mousse puts an end to punctures but is heavier, costs more and cannot be adjusted; a tube lets you adjust the pressure, but can puncture or get pinched.

Why choose PIRELLI?

PIRELLI, founded in Milan in 1872, has won more than 80 FIM Motocross World Championship titles. In 2025, nine of the top ten in the final MXGP standings rode on Pirelli tyres.

When should you replace the tyre?

Rounded, split or torn knobs from rocks, cut or cracked sidewalls: it needs replacing. In racing, it is changed as soon as the knob edges are no longer sharp; for leisure riding, at the latest when the knobs have lost about half their height. Rocks wear the knobs much faster than dirt, and a tyre stored for several years hardens, even if it has never been ridden.
