Junior helmet size guide
Measure around the widest part of the head, approximately 2.5 cm above the eyebrows. Use the junior measurements below rather than LS2's adult helmet chart.
| Junior size | Head circumference |
|---|---|
| S | 47-48 cm |
| M | 49-50 cm |
| L | 51-52 cm |
LS2 advises choosing the smaller size when a measurement falls between two sizes. A new helmet should fit firmly and evenly without painful pressure points, and it should not move independently when the rider turns their head.
Goggles and compatibility
This is an off-road helmet with an open eye port. LS2 does not list a face visor or goggles as supplied with the model, so suitable junior motocross goggles should be selected separately and checked for a secure fit around the eye port.
LS2 does not list the Fast Evo II Mini as prepared for an intercom system.
