Alpinestars Supertech SM10 Flood Helmet ECE 22.06 Silver Black Orange Fluo Matt and Gloss

The Alpinestars Supertech M10 Flood is the brand's flagship motocross and off-road helmet, finished here in a Silver, Black and Orange Fluo colourway with a mix of matte and gloss surfaces. It pairs a multi-composite carbon and aramid shell with a four-density EPS liner and MIPS, and it carries ECE 22.06 certification.

It suits motocross, enduro and off-road riders who want a light, heavily ventilated helmet with a precise fit. Four separate shell sizes across six consumer sizes keep the helmet anatomically correct rather than simply padded out, while the patented A-Head Fitment System lets you fine-tune the angle and height the helmet sits on your head.

Note: the Supertech M10 is produced in ECE 22.06 and ECE 22.06/DOT versions; this listing covers the ECE 22.06 model.

• 28 intake and exhaust ports in total — 18 intakes and 10 exhausts, excluding the eye port
• Sculpted chin bar with collarbone relief, softer extended EPS and a flexible rubber covering
• Removable semi-soft polymer side pads spread impact energy over a larger contact area
• ERS Emergency Visor Release for controlled visor removal

• 1260 g in ECE trim for a size medium

Check the fit before first ride and use the A-Head Fitment System to set the angle and height the helmet sits at, then confirm the retention strap is correctly threaded and snug.
Clean the shell with lukewarm water and a mild soap on a soft cloth — avoid petrol, solvents, thinners and other petrochemicals, which can damage the composite shell, paint and EPS.
After muddy rides, soak and rinse rather than scrub, and clear mud from the 18 intake and 10 exhaust ports so airflow is not blocked.
Remove the side pads for cleaning where needed and refit them fully seated before riding.
Handle the MIPS layer and EPS gently; do not press, gouge or modify the liner, and do not apply solvent-based stickers, adhesives or paint to the shell.
Use the ERS Emergency Visor Release only in an emergency or when servicing the visor, and make sure the visor is properly relocated and tightened afterwards.
Let the helmet and any damp padding dry naturally away from direct heat sources, heaters and hair dryers.
Store in a cool, dry place out of direct sunlight, ideally in a helmet bag, and do not rest it on mirrors or bar ends where the liner can be deformed.
Replace the helmet after any significant impact or crash, even if no damage is visible — EPS protection is designed to work once.
Do not carry or hang the helmet by the strap, and keep it away from fuel vapours in storage or transport.
