MT Helmets Thunder 4 SV Full Face Motorcycle Helmet – DOT + ECE + CCC Certified, ABS Shell, S–4XL
MT Helmets Thunder 4 SV Full Face Motorcycle Helmet – DOT + ECE + CCC Certified, ABS Shell, S–4XL
The MT Helmets Thunder 4 SV is a triple-certified full-face helmet in a clean modern profile — certified independently to DOT (US), ECE (Europe), and CCC (China). An injection-moulded ABS shell, EPS impact liner, clear visor, quick-release chin strap, and soft polyester comfort lining make it a straightforward, reliable helmet for street, touring, and off-road riding. Seven sizes run from S to 4XL (67–68cm) — a genuine advantage for larger riders who struggle to find a certified full-face at the top of the range.
✔ Key Features
DOT + ECE + CCC Triple Certification: Independently tested against three separate national impact protocols — ECE in particular requires pre-market independent laboratory testing
Widest Size Range S–4XL: Seven sizes up to 67–68cm — certified full-face helmets are uncommon at 4XL, making this a real advantage for larger riders
ABS Injection-Moulded Shell: Distributes impact force laterally across the shell before transferring it to the EPS liner, with impact performance retained across a wide temperature range
EPS Impact Liner: Variable-density foam absorbs energy through irreversible cellular crush to keep force away from the skull
Clear Visor: Unobstructed light transmission across day, dusk, and artificial light, with a perimeter gasket sealing against wind noise and cold air
Quick-Release Chin Strap: Glove-friendly single-hand operation with the same retention security as a D-ring, and the system responders use to remove a helmet without rotating it
Polyester Comfort Lining: Wicks moisture from the scalp; removable for washing to maintain hygiene and consistent fit
All-Season Full-Face Design: Sealed shell and visor suit year-round street, touring, and off-road use

Size Tip: Measure at the widest point of your skull — above the eyebrows, over the ears, and around the back. Take three readings and use the largest. A correctly sized helmet applies firm, even pressure with no gaps and feels snug for the first 15–20 minutes before the liner settles. If it feels comfortable immediately, it's likely one size too large. At the larger sizes (3XL–4XL) head shape varies more than circumference alone, so confirm the helmet sits without persistent pressure points before the return window closes. If your measurement falls at a size boundary, choose the larger size.
