Alpinestars - Supertech S-M8 Radium Helmet

At the outset of the MX helmet project, Alpinestars product philosophy was applied and a set of specific objectives set: Create the most advanced, protective and performance enhancing helmet possible. Primary objective: protection – to create the most high performance protection possible. Secondary objective: to give excellent ventilation, comfort and reduced weight. Alpinestars approach to the creation of the advanced technology in the Supertech M8 draws on its depth of experience from over half a decade of world class innovation across the spectrum of motorsports and especially, its deep rooted commitment to motocross. As with all other categories of technology that Alpinestars has mastered, bringing a new, highly complex, product to fruition requires specialist experience and know-how and a project plan led by the best brains in protection development. Hence Alpinestars Helmet Development Department was created and given the brief to research and develop the most protective and most comfortable possible motocross helmet. The goal was to allow riders to push the limits of performance, benefiting from confidence inspiring safety technology, reduced weight distribution to minimise muscular effort in the neck, shoulders and back and improved physiological and cognitive performance with a supremely well fitting and well ventilated construction, optimizing comfort while riding. The design is coherent to Alpinestars philosophy and shares distinctive themes with other products in the portfolio; a smooth, attractive, profile which is streamlined and free of any external channels and features that might act as a load point in an impact, or compromise the overall integrity of the construction. The surface curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider’s head from direct force to the skull and referred to the neck and spinal column. The aperture is designed to accommodate a wide variety of goggles and the air vents in the shell are located to maximize ventilation efficiency. The S-M8 shell has been profiled with performance as a priority and with a design style that identifies the profile of the helmet and its sculpted surface as uniquely ‘Alpinestars’.

Features:

  • Unique, patented, visor release system is another key attribute incorporated into the design of the Supertech M8.
  • Visor release is a key part of overall protection performance in the helmet and a major influence on the distinctive, flush, design of the outer shell profile.
  • Alpinestars has developed a unique visor release system which, while ensuring the mounting is held securely in place for riding over the most extreme terrain and any track conditions, provides exactly the right level of resistance to ensure the visor detatches from the helmet shell if it is subjected to a significant impact – no matter what the angle.
  • The S-M8 visor release mechanism is conceived to avoid the inherent weaknesses in other types of anchoring systems. Maintaining shell integrity is vital for safety and with the possibility of multi-directional forces impacting on the visor, separation at the critical point of loading reduces potentially damaging leverage and rotational accelerations that refer injury to the rider’s neck and spine.
  • Ventilation is a key feature of the Supertech M8.
  • Heat mapping tests have resulted in specifically designed ducting which produces a positive flow into the helmet over and around the rider’s head, improving comfort while riding and reducing the on-set of heat stress in extreme conditions.
  • The visor design of the S-M8 is also an integral part of the ventilation system as it is profiled to direct airflow, acting as a channel to concentrate and smooth the flow into the shell. The Supertech M8 liner design is formed to optimize airflow channeling around the rider’s head before being extracted from the S-M8 through rear exhaust vents to ensure positive pressure is maintained with constant airflow while riding.
  • Hydration system compatibility.
  • The Supertech M8 helmet lining design includes canals which allow a tube to be incorporated on either side of the shell. This is a feature extensively tested by Alpinestars rally raid and enduro riders enabling convenient fitting and connection to a hydration system.
  • Interior lining comfort.
  • Removable liner cover is washable and features a cool-max fabric interior and anti-bacterial talent yarn for long-lasting freshness and quick-dry performance between riding sessions.
  •  Helmet features TPE coating washable surfaces to improve maintenance and increase durability.
  • Additional cheek pad set offering increased thickness of +5mm, for tighter fit adjustment – available separately.
  • 1360g for size Medium (DOT)

Fits amazing!
Color: Brown, Color: Brown
Fits just right, like a glove on my desk. Make sure you take measurement on the width, it is long. Saves a lot of space. Easy to assemble, but make sure you’re aligning the front with the front on the 1 & 2. Sturdy, amazing quality.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
