Kali Dirt Bike Helmets

KALI FRP TeamRider HELMET

Presenting one the most advanced MX helmets imaginable, the Kali Protective PRANA™ Helmet. Weighing just 1250 grams, it’s lighter than the human brain and a lot less than the average dirt helmet. The heart of Kali Protective PRANA™ helmet is the introduction of COMPOSITE FUSION™ Plus technology.

Years in development, this revolutionary construction incorporates pyramids of different CONTEGO™ foam densities to provide the softest materials next to your head. With a carbon shell providing the skeleton, COMPOSITE FUSION™ Plus technology provides not only one of the lightest possible helmets but also one of the most protective.

Features:

  • Fiberglass shell with COMPOSITE FUSION™ Plus construction
  • Dual Density CONTEGO™ EPS Liner
  • Integrated airflow system
  • Antibacterial, removable, washable liner
  • Breakaway visor design
  • Meets or exceeds AMA, FIM, CCS, WERA racing standards
  • Safety certifications include Australian Standards, ECE22.05, DOT (FMVSS 218)
  • Includes Kali Helmet Storage/Travel Bag

The Kali Prana FRP is only 50gm heavier than the carbon graffitti model,  at a significant cost saving. Other than having a fiberglass shell it is identical in all other respects!

Kali

Kali Protectives is designed for riders who demand exceptional performance and uncompromising comfort. Kali Protectives came from a significant breakthrough in helmet safety technology, enabling them to use a thinner shell creating a lighter and stronger helmet. No safety technology exists that can completely prevent injury, but they can significantly reduce the chance of trauma. Their goal is to deliver the absolute best available protection to riders.

The Bicycle Store is an authorised dealer of Kali bike helmets.

Sizing Guide for Prana Moto Helmets

The most important part in helmet sizing is to get a snug fit around the crown, or widest part, of your head. Extra padding is supplied to then custom fit to your cheek area. 

Measure around your head, just above your eyes, as shown in the pop up image above.

Select your helmet size from this table: 

S =   55-56cm

M =  57-58cm

L  =  59-60cm

XL = 61-62cm

 

If you do not like the fit once you have received the helmet, you may return it for an exchange or refund. No Hassles.

Exchanged helmets are returned to you with Free Shipping.

Composite Fusion PLUS Technology in Kali Dirt Bike Helmets

The purpose of a helmet is to absorb the energy of an impact to minimize or prevent a head injury. A helmet does this by transferring the energy to the foam, which crushes as it absorbs the impact. However, the way in which a helmet is constructed plays an important role in how the helmet absorbs the energy.

There are basically two ways that most companies construct a helmet. The traditional construction of full-face and skate-style helmets features impact foam glued to a hard outer shell. The other common way, which is typically used in cross-country-style helmets, has the foam molded directly to the hard exterior shell and is commonly referred to as in-molding.

Using an advanced form of in-molding, Kali has developed two designs that effectively disperse impact energy better than a traditional full-face helmet, which allows them to offer the same or better protection as other helmets in a lighter package. The secret is in their patented manufacturing technique and tooling; Kali is the first company to figure out how to produce the full outside shell of a full-face and then to have the EPS injected inside that formed shell. Here’s a quick overview of a traditional full-face helmet construction compared to Kali’s COMPOSITE FUSION and COMPOSITE FUSION Plus technology.

In the above picture, a traditional full-face helmet design features foam glued to the inside of the outer shell. While this helmet construction can provide adequate protection, it is not ideal because the design can leave gaps in between the foam and the shell. When a helmet sustains an impact, the force must first break through the hard shell before it gets to the part of the helmet that dissipates the energy. Besides offering a more durable helmet covering, the main role of a hard exterior is to help spread out the impact energy across more of the foam inside the helmet to absorb the shock. In addition, many helmet manufacturers use dual density foam to help absorb the impact energy more efficiently.

Kali’s Composite Fusion design provides a super tight (almost molecular) bond between the helmet shell and the energy absorbing material inside. This tight connection between these two materials prevents gaps, which transfers shock more efficiently through to the softer EPS foam materials. It also allows Kali to use a thinner shell that breaks down faster and allows the energy to be absorbed more efficiently. Kali also uses dual density foam, with the softer material near the head, to dissipate the energy sustained from an impact.

Taking the COMPOSITE FUSION technology a step further, Kali’s COMPOSITE FUSION  Plus has the same super tight connection but also incorporates a special impact foam design. Using geometric shapes of different densities inside the foam, the Composite Fusion Plus technology further helps dissipate the shock forces as they travel through the foam. In this image, the different colors of the dual density foam highlight the pyramid shape of the Composite Fusion Plus design, with the softer material near the head. Interestingly enough the Plus design is based on an Australian Invention, CONEHEAD TECHNOLOGY, which won World Inventor Of the Year in 2012 for its creator Don Morgan of Queensland!

G-Force Scale

Based on thousands of actual test results, this G-Force Scale demonstrates how impact force is registered and dissipated as the helmet takes impact. As you can see by the illustration, different types of helmet construction and materials absorb and dissipate impact energy differently.

Traditional As a traditional helmet absorbs the force of an impact, the transition from the hard shell to the foam is highlighted by a dip in the impact energy being absorbed (as the shell breaks down). This is not only inefficient, but can allow the energy to slightly magnify rather than continue dissipating.

COMPOSITE FUSION™ The way in which a COMPOSITE FUSION helmet absorbs the energy of an impact is much more fluid and effective than a traditional helmet. The smooth curve provides constant impact dissipation through the super tight shell/foam connection, reducing energy spikes.

COMPOSITE FUSION™ PLUS Compared to a COMPOSITE FUSION helmet, a COMPOSITE FUSION Plus helmet is even more efficient at absorbing impact energy, thanks to it additionally channeling impact energy laterally through its geometric shapes of dual-density foams. This promotes constant energy dissipation until the impact is relieved.

The Verdict

The G-Force Scale sidebar is a good way to compare the different ways that a Traditional, COMPOSITE FUSION and COMPOSITE FUSION Plus helmet design deals with energy absorption. You can see that Kali’s helmet designs disperse impact energy much more effectively and efficiently than a traditional full-face helmet. This not only makes their helmets safer but also allows them to be lighter.
