Buying Guide
Your helmet is the one piece of gear that matters most in a crash, so choose it based on protection, fit and the type of riding you do. Start with the basics and work toward the features that add value for your use.
Selection Criteria
- Certification: Look for DOT (required for road use in the US) and, for motocross, ASTM or similar off-road standards listed by the manufacturer.
- Fit: The helmet should feel snug all around with no pressure points, and it should not shift when you shake your head.
- Coverage: Full face helmets are the standard for dirt bike riding, with chin bars that protect the jaw.
- Weight: Heavier helmets can cause neck fatigue over long rides.
- Ventilation: Vents matter more in hot conditions, and they should be easy to open and close while riding.
Important Features
- MIPS: A low-friction liner designed to reduce rotational forces in angled impacts. Several Bell and Fox models include it.
- Visor and goggle fit: Make sure the visor is easy to adjust and that your goggles sit flush against the foam.
- Collarbone protection: Bumpers at the base of the shell help with chest and neck coverage.
- Removable liners: These make cleaning easier after muddy rides.
Specs to Check
Manufacturers usually list head circumference in centimeters or inches. Measure your head about one inch above your eyebrows, around the widest point, and compare that to the size chart for the specific model. Sizing varies between brands, so do not assume your usual size will match.
Choosing by Need
- Motocross and track riding: Prioritize MIPS, a race-style shell and a snug fit. The Fox Racing V Core MIPS suits this need.
- Trail and recreational riding: A versatile full face with good ventilation works well. The BELL Transfer is aimed at this use.
- Beginners on a budget: A DOT-approved full face helmet covers the basics. The ILM Model 128S is one option, though check the sizing chart closely.
- Riders who want a wide size range: The BELL MX-10 MIPS offers sizes from XS to XXL.
Things to Watch Out For
- Do not buy a helmet that is too large, even if it feels comfortable at first. Foam compresses over time, and loose helmets move in a crash.
- Replace any helmet that has been in a crash, even if the damage is not visible.
- Check the manufacturer’s replacement guidance, which often suggests replacement every few years depending on use and storage.
Helmet safety is a serious matter. If you are unsure about fit or certification for your specific riding, consult a qualified motorcycle or off-road gear fitter before you ride.
FAQ
Is a bell helmet dirt bike model worth buying for beginners?
Yes, if you choose a model with DOT certification and a snug, well-measured fit. Many beginners do well with a full face helmet that covers the jaw and has a comfortable liner. Start with a size chart measurement rather than guessing.
What is MIPS and do I need it?
MIPS is a liner system designed to reduce rotational forces during angled impacts. It is not required for legal riding in most places, but it is a common feature on higher-end motocross helmets and many riders consider it worthwhile.
How do I know my helmet size?
Measure your head circumference about one inch above your eyebrows, around the widest part. Then match that measurement to the specific brand’s size chart, because sizes differ between manufacturers.
How often should I replace a dirt bike helmet?
Manufacturers commonly recommend replacing a helmet after a crash or after several years of use, depending on storage and exposure to sun and sweat. Check the owner’s manual or product documentation for the exact guidance.
Can I use a dirt bike helmet for street riding?
Only if it carries DOT certification. Motocross helmets are often designed for off-road conditions, so confirm the certification on the label before using one on public roads.
Should I buy a full face or open face dirt bike helmet?
For motocross, trail and off-road riding, full face helmets are the standard because they protect the jaw and chin. Open face helmets offer less coverage and are generally not recommended for dirt bike use.
Do goggles fit with every dirt bike helmet?
Most full face helmets work with goggles, but fit varies. Check that your goggle strap and frame sit flush against the helmet’s foam and that the visor opening does not create gaps.
Conclusion
For motocross and serious track riding, the Fox Racing V Core MIPS and the BELL MX-10 MIPS are the stronger matches, since both include MIPS and suit aggressive riding. If you ride trails and want a versatile full face, the BELL Transfer is a sensible choice. Beginners on a tighter budget can consider the ILM Model 128S, provided they measure carefully and check the sizing chart. Whichever bell helmet dirt bike model you pick, prioritize certification, a snug fit and a helmet you will wear every time you ride.
