Troy Lee Designs SE4 Polyacrylite Yamaha L4 MIPS Youth Off-Road Helmets

YOUTH SE4 POLYACRYLITE YAMAHA L4 HELMET.

Weighing in at 1500 grams, the Youth SE4 Polyacrylite delivers many of the top-shelf features developed for the SE4 Carbon/Composite, including MIPS safety technology to reduce internal head injury by absorbing rotational impact force. The Polyacrylite Yamaha L4 combines sharp-looking MATTE Yamaha graphics and the SE4s advanced features with a budget-friendly MSRP that Yamaha riders are sure to appreciate.

  • Durable, lightweight Polyacrylite shell reduces cost without compromising rider safety
  • MIPS (Multi-directional Impact Protection System) liner absorbs rotational force that would otherwise transfer to the brain, helping reduce the risk of concussion and internal head trauma
  • Budget-friendly design still showcases MIPS (Multi-directional Impact Protection System) advanced safety enhancement, reducing transfer of rotational impact force on the brains
  • Chinbar reinforced with EPP foam liner for improved durability without excess weight
  • Efficient negative pressure ventilation system routes cooling airflow through 16 high-flow intake ports and six exhaust vents
  • 3D contoured cheek pads offer fine-tuned anatomical fit and feature quick-release functionality to facilitate safer helmet removal by EMS responders
  • Removable liners and cheek pads interchangeable for a customized refined fit from the six available standard sizes (X-Small, Small, Medium, Large, X-Large, 2X-Large)
  • Exceeds certifications for DOT FMVSS 218 and ECE 22.05

  • Sizes: Medium, Large
  • SKU: 112877003, 112877004

Troy Lee Designs Helmets Size Chart

CORRECT HELMET SIZING

Each helmet model has small differences in its shape that ultimately affect the fit. For this reason, it is essential to test a helmet before buying it. Test whether it sits on your head properly by putting on the helmet and moving your head to the left and right, as well as up and down while holding the helmet firmly with both hands. If your head can move too freely within the helmet, we recommend that you try a smaller size. If you feel local pressure points, then choose a helmet that is one size larger, or perhaps try on a different model.

(H) HEAD

Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, repeat for good measure and use the largest measurement.
