Fox V Core Helmet vs Alpinestars SM7 Helmet

The Alpinestars SM7 is the stronger helmet on paper: a fiberglass, carbon and Aramid composite shell, ECE 22.06 plus DOT certification, 20 vents and a lighter listed weight. The Fox V Core is a solid entry-level motocross lid with Mips, DOT certification and a removable washable liner, but its polycarbonate and ABS shell, single certification and heavier build put it a step below. Buy the SM7 if you ride hard, race, or want the better shell and fit system. Buy the V Core if you want a straightforward Mips-equipped off-road helmet and don't need ECE approval.

  • Choose the Fox V Core if you want a simple DOT-certified motocross helmet with Mips and a washable liner, and you don't need ECE 22.06 approval.
  • Choose the Alpinestars SM7 if you want a lighter composite shell, ECE 22.06 and DOT certification, more ventilation and a more adjustable fit.

What reviewers say

Alpinestars SM7 Helmet

  • 4.8 / 550 ratings

Riders rate the SM7 highly, at 4.8 out of 5 from 50 ratings, and praise its light weight, ventilation and secure fit. Complaints center on the fiddly Double-D strap and the price of stepping into this tier.

What people mention
  • WeightPraisedOwners say it feels light on long rides compared with heavier dirt helmets.
  • VentilationPraisedRiders report strong airflow through the intake and exhaust ports in hot conditions.
  • FitPraisedThe A-Head system lets riders tune the angle and height for a secure fit.
  • BuckleCriticisedThe Double-D strap is seen as safe but slower to fasten and unfasten.

Questions and answers

Which is better for track or race use?
The SM7. It carries ECE 22.06 alongside DOT, uses a composite shell and has the A-Head fitment system. The V Core is DOT only.
Does the Fox V Core have Mips and the SM7 not?
Yes. Fox lists Mips on the V Core. Alpinestars lists a curved shell and PLASMA side pads on the SM7 but no Mips liner.
Which is lighter?
The SM7. Alpinestars lists about 1340 g DOT and 1280 g ECE. Fox lists about 1470 g in size M for the V Core.
Which has better ventilation?
The SM7, with 13 intake and 7 exhaust ports against 9 intake and 4 exhaust on the V Core.
Is the SM7 worth stepping up to?
If you want ECE 22.06 certification, a composite shell and less weight, yes. If you mainly need a DOT-certified Mips helmet for casual off-road riding, the V Core covers that.
Which fits a wider range of head sizes?
The V Core spreads its range over four shell and five EPS sizes. The SM7 uses three shell sizes but covers XS to XXL with the A-Head adjustment.
