Shoei vs. Arai: A Motorcycle Helmet Face-Off
When I embarked on the task of comparing Shoei and Arai helmets in this article, I initially underestimated the complexity of the endeavor. We had previously dissected comparisons such as Sena vs. Cardo, so I assumed this task would be straightforward. However, as my research unfolded, it became apparent that selecting the best motorcycle helmet was a more intricate and nuanced process, akin to life's perennial debates - Coke or Pepsi, Nature or Nurture, Good or Evil. Now, we add Shoei or Arai to the list.
Shoei and Arai have ascended to their esteemed positions in the motorcycle helmet industry for good reason.
When it comes to this comparison, a considerable portion of the decision-making relies on individual preferences. In the following sections, I will analyze key aspects of each helmet to furnish you with the knowledge required to make an informed choice when considering a purchase.
Motorcycle Helmet Safety
Undoubtedly, the paramount concern in selecting a motorcycle helmet is safety. The primary role of a motorcycle helmet is to shield your head during accidents, and two governing bodies, the DOT (Department of Transportation) and the ECE (Economic Commission for Europe), have established strict standards to guarantee the helmet's efficacy. A third set of standards, the "Snell rated," imposes even more stringent criteria than DOT, although it doesn't attain the exacting precision of the ECE standards. In reality, the ECE standards amalgamate DOT and Snell standards while adding a few of their own.
So, which of these two brands produces the safer helmet? Both Shoei and Arai comply with local safety standards. However, the distinction emerges when you delve deeper into their approach to safety. Arai prioritizes optimizing the helmet's safety in real-world scenarios, acknowledging that helmets can absorb the full energy of an impact but emphasizes the importance of distributing this energy across various parts of the helmet. This strategy accounts for rotational impact and energy deflection, fortifying their dedication to safety.
Conversely, Shoei adopts a broader interpretation of safety, aiming to minimize rider discomfort and fatigue. Their philosophy asserts that a lighter helmet alleviates strain on the neck muscles, ensuring a more comfortable riding experience and, by extension, reducing the likelihood of an accident.
One of Shoei's innovations in safety is the coverless face shield, a feature that most other helmet manufacturers have since adopted. However, Arai remains steadfast in their belief that this innovation compromises safety. Although the veracity of Arai's claim remains to be definitively established, their unwavering commitment to safety elevates their standing in the market while challenging their primary competitor - a strategic move indeed.
Fit of Motorcycle Helmet
Selecting a helmet that fits snugly on your head is crucial, considering that everyone's head has a slightly different shape. Arai offers a more extensive range of head shape options, including long oval, round oval, and intermediate oval. It's worth noting that not all head shapes are available in all models, so trying on a variety of models is advisable. Furthermore, Arai provides a substantial array of internal liner and cheek pad options, allowing for a customized fit once you've identified the most suitable model.
In contrast, Shoei predominantly offers one head shape - intermediate oval. While this should comfortably accommodate 75-85% of American riders, individuals with more unique head shapes might find it less accommodating. Nevertheless, Shoei does provide various interchangeable internal components, permitting fine-tuning of the helmet's fit.
Motorcycle Helmet Shell Construction
Both Arai and Shoei employ proprietary shell construction techniques, often incorporating multiple layers of fiberglass. Arai meticulously constructs their helmets by hand, ensuring a hands-on approach to every aspect of production. In contrast, Shoei employs more contemporary manufacturing methodologies.
For someone without specialized knowledge in chemical engineering or structural fiberglass properties, differentiating between the two brands' shell designs can be challenging.
EPS Liner on Motorcycle Helmets
The EPS (expanded polystyrene) liner, located within the helmet, serves as the component responsible for absorbing energy during impacts. When the liner absorbs energy, the cells within it are compressed, minimizing the amount of energy transmitted to your head. However, the EPS liner functions more like an airbag than a sponge, as once its cells have compressed during an accident, they cannot effectively absorb energy again. For this reason, it is universally recommended to replace your helmet after any accident.
Arai's EPS liner is a single-piece construction, varying in density across different sections of the helmet. This design enables the helmet to perform optimally under various impact conditions, whether it's a low-speed collision with a side impact or a high-impact force on the top of the helmet.
Shoei employs a dual-layer, multi-density EPS liner. The top portion of the liner features a softer density foam for immediate impact absorption. In 2018, Shoei introduced an updated liner that claims to reduce rotational energy by 15%.
Motorcycle Helmet Weight
With numerous helmet models available from both brands, it is crucial to compare equivalent models to gauge weight differences accurately. Our initial assessment indicates that Arai helmets tend to be marginally lighter than Shoei's. However, this disparity may fluctuate depending on the specific model. Consequently, trying on helmets from both brands to assess comfort is recommended.
Price of Motorcycle Helmets
Both Arai and Shoei helmets are positioned as premium products, justifiably so given their relentless commitment to safety and innovation. Nevertheless, Arai helmets typically carry a slightly higher price tag compared to their Shoei counterparts.
Your motorcycle helmet arguably ranks as the most significant purchase after acquiring your motorcycle. In the perpetual debate between Shoei and Arai, here's a summary of the critical considerations:
Safety: Arai gains an edge for potential collision scenarios, while Shoei's emphasis on comfort makes it an appealing choice for extended rides.
Fit: Arai excels with its three head shape options for unparalleled flexibility.
Shell Construction: A tie, as the shell design nuances are challenging to distinguish.
Liner: Another tie, with both brands offering options that prioritize safety and comfort.
Weight: Arai is slightly lighter, but this can vary by model. Testing both brands' models for comfort is advisable.
Price: Shoei is marginally more affordable, although both brands occupy the premium segment.
Ultimately, either brand is a commendable choice. We encourage you to try on various helmets and find the one that suits you best, aligning with your unique preferences and riding style. Once you've made your choice, don your helmet and embark on your next ride.
