Kart Racing Helmet – Frequently Asked Questions (FAQ)
Remember that safety is paramount in kart racing, and choosing the right helmet and maintaining it properly is essential for your protection on the track. Consult the professionals at Competition Motorsport any time you have specific questions about your racing helmet.
What is the best helmet for kart racing?
The Stilo ST5 CMR Carbon Fiber kart helmet is widely considered one of the best youth karting helmets, offering premium features for serious kart racers.
Why do I need a racing helmet?
Auto and kart racing helmets are essential for protecting your head in high-speed accidents. They also shield against debris and, in some motorsports, fire—making them a non-negotiable safety requirement.
How do I choose the right size Kart Racing helmet?
Use a flexible tape to measure the circumference of your head just above your eyebrows and ears. Compare the measurement to Bell’s sizing chart. For more help, read our blog on how to fit your helmet properly at Competition Motorsport.
What safety standards should I look for in a youth kart racing helmet?
Look for the FIA CMR-2106 certification for karting.
Can I use a motorcycle helmet for kart racing?
No. Motorcycle helmets lack the kart-specific certifications and features like proper ventilation and impact resistance optimized for karting. Always use a helmet rated for motorsport competition.
How often should I replace my kart racing helmet?
Replace your helmet every few years depending on usage and the manufacturer's guidance. If it’s been dropped, involved in an impact, or shows signs of wear, replace it immediately.
Are expensive racing helmets safer than budget ones?
Yes, typically. While both must meet minimum safety standards, premium helmets offer lighter materials, better fit, improved aerodynamics, and enhanced comfort, all of which impact race performance and fatigue.
How do I maintain and clean my kart racing helmet?
Clean the exterior and interior using a helmet-specific care product like the Molecule Helmet Care Kit. Avoid submerging the helmet or using abrasive cleaners. Visors should be cleaned gently to avoid scratching.
Do I need to wear a balaclava under my kart racing helmet?
While not required for all karting events, a balaclava enhances comfort, keeps your helmet liner clean, and helps wick sweat. Fire-rated balaclavas are mandatory in sanctioned auto racing and recommended for high-performance karting.
Can I wear glasses with my kart racing helmet?
Yes. Wide eye ports, make it compatible with most prescription glasses and racing eyewear. A good fit ensures the glasses remain stable and fog-free.
Are carbon fiber helmets better?
Carbon fiber helmets are lighter and stronger, reducing fatigue during long races while offering excellent impact protection. They are a top choice for competitive drivers.
Can I use a used helmet for racing?
It’s not recommended. Damage or degradation may not be visible, and older helmets might not meet current safety standards. Always buy new from an authorized dealer like Competition Motorsport.
How can I prevent helmet fogging during races?
Use a visor with built-in anti-fog technology like Bell’s DSAF system, or apply an anti-fog spray or insert. Keeping your helmet well-ventilated also helps.
What's the importance of proper helmet ventilation?
Good ventilation helps manage heat and moisture inside the helmet, reducing fatigue and keeping you focused throughout your race.
How do I store my kart racing helmet between races?
Store your helmet in a cool, dry place away from direct sunlight. Use a padded helmet bag like our Competition Motorsport Evo Helmet Bag to prevent damage during transport or storage.
What is the difference between Snell K2020 and CMR2016 certifications?
Snell K2020 is designed for adult karting helmets, focusing on impact protection. CMR2016 is tailored for drivers under 15, offering a lighter helmet to reduce neck strain while maintaining safety standards.
Are tear-off visors necessary for kart racing?
Tear-off visors are beneficial in maintaining clear vision during races by allowing drivers to remove a dirty visor layer quickly. They are especially useful in outdoor karting where debris and dirt are common.
How do I know if my helmet is still safe to use?
Helmets should be inspected regularly for signs of wear or damage. If a helmet has been involved in a significant impact or shows signs of degradation, it should be replaced immediately. Additionally, helmets should be replaced every 5 years, even if no damage is visible.
Can I customize my kart racing helmet?
Yes, many manufacturers offer customization options for fit and aesthetics. However, any modifications should not compromise the helmet's structural integrity or safety certifications.
