DescriptionThe whole story▼

The outside of a motocross boot leg is the face that meets the ground in a low-side and grinds along ruts and rocks. Sidi sells that outer shell of the Crossair X as a separate part, so a scarred or cracked panel can be replaced on its own. The list entry reads Crossair X Out Leg, chart position 397, available in Black and White.

Key Features

  • Original Sidi outer leg shell for the Crossair X
  • Hard plastic, per the Sidi parts list
  • Two colours: Black and White
  • Sidi chart position no. 397

Role of the outer shell

This panel covers the lateral side of the lower leg, away from the bike. It spreads impacts from falls and trail obstacles across a wider area and protects the inner structure and liner from abrasion. Because it is the panel most exposed to sliding contact, it is often the first one to show deep wear on a hard-used boot.

Colour choice and fit

Choose Black or White to match the rest of your boot. Sidi gives no size split for this item, so one version per colour covers the Crossair X range. The white shell suits the lighter Crossair X schemes, the black one darker builds; check your boot before ordering.

What You Should Know

Sidi names the Crossair X for this part and nothing else. The list spells it 'Oout leg', which is a typing error in the source. Install it according to the Sidi spare-parts chart or have it fitted by a Sidi dealer.
