Product Details

The GMAX MX-46Y Youth Helmet is built for young riders who need lightweight comfort, dependable protection, and plenty of airflow on the track or trail. At approximately 2.2 lbs., the MX-46Y is designed to keep youth riders comfortable without adding unnecessary weight.

A fully adjustable interior allows the helmet to fit youth small, medium, and large sizing, helping the helmet adapt as the rider grows. The removable and washable liner also makes cleanup easier after hot, dusty rides.

For ventilation, the MX-46Y uses 19 vents to help move air through the helmet and reduce heat buildup. A high-flow removable mouth vent with washable filter, vented roost deflector, large eye port, and flexible adjustable visor complete the off-road-focused design.

GMAX Helmet Size Charts

To find your approximate helmet size, use a soft sewing tape measure. Start at your forehead about one inch above your eyebrows and measure around the largest portion of the back of your head. If you do not have a soft measuring tape, use a string or phone charging cord, then lay it flat and measure it with a ruler.
