One Goal. One Vision

Alpinestars is once again leading the way in developing rider safety. Having pioneered countless innovations in boots, suits and gloves, notably the development of external protection on road race boots in the early 80’s and more recently employing the philosophy on its leather suits, they are now introducing a new dimension into race suit technology – a fully autonomous, multiple field data acquisition system. The Advanced Safety Technology suit (AST).

Fitting telemetry and acquiring data from race bikes and cars has been common practice for some years, however, acquiring data directly from the body of the rider/driver has not and Alpinestars is developing technology to allow technicians the ability to analyze the gravitational and impact forces, as well as the physiological effects experienced by a human when pushing the limits of a high performance race machine.

During the weekend of the German Grand Prix at the Sachsenring, MotoGP rider John Hopkins wore a leather suit equipped with the new A.S.T. system. Although indistinguishable from his usual race suit, John’s body was constantly monitored by a series of accelerometers, impact and physiological sensors.

The impact sensors are mounted on both external and internal surfaces of the suits protectors to measure the loads sustained and absorbed in a fall, without impeding or endangering the rider in any way. The sensors record the maximum impact value subjected to the rider, providing real situation data, above and beyond the test simulations currently conducted in the Alpinestars laboratory.

The custom data processor and solid-state memory, encased in an impact resistant structure and hidden in the back hump on John’s suit, acquire data throughout each session which can be downloaded immediately into a laptop plugged into a connector on the suit. The information can then be studied to analyze pressure point values, lateral G loads experienced, the rider’s pulse and the suit’s cooling performance.

The benefit of developing such technology is the tremendous amount of information that can be gathered about the stresses borne by a rider and the performance of safety equipment during a race and in the event of a fall. Alpinestars’ goal is to develop the technology to measure all the dimensional forces at work upon a rider and to allow greater understanding of material performance thereby improving safety both on the racetrack and ultimately on the road.

Alpinestars Bionic Tech 2 Neck Support Adult Off-Road Body Armor

The Bionic Neck Support Tech 2 is constructed from an advanced, high-performance carbon polymer compound and is designed to help prevent injury in a crash situation by dissipating and diverting impact forces away from the neck and spine. The BNS functions when the rider's helmet makes contact with the frame at the moment of a crash, thus providing a clean, solid surface which instantly channels damaging, compressive impact energy away from the neck and on to the BNS. Featuring Alpinestars' exclusive and revolutionary rear stabilizer for progressive force relief (PFR) the BNS Tech 2 is designed for use in motocross and off-road riding and offers a highly personalized and stable fit while incorporating innovative new features such as a new quick release locking system.

The Bionic Tech 2 is constructed from an advanced high-performance fiber polymer compound
Complete design facelift and technical upgrade including new lightweight rear and chest padding and updated chinplate design
Structural integrity and frame strength against heavy impact energies during a crash
Ultra-lightweight performance and comfort while riding
Less weight than its pyellow-fluoecessors
Resilience to low temperatures, below 0°C
Designed to provide a customizable, secure and personalized fit with the SAS (Size Adapter System) for a versatile fit
The stretch fabric laminated foam padding kits are adaptable and the interchangeable EVA foam pads allow compatibility wit body impact shield systems
Lightweight strap System can be worn over or under the jersey
Incorporates a bio-organic engineering design for superb ergonomics
Rear stabilizer promotes PFR (Progressive Force Relief) and dissipates energy loads by transmitting them across the back and shoulders and away from spine (thoracic vertebrae), and is connected to the frames via pivot key
Frame construction promotes improved contact with helmet during impact - including rear support edge that fits closer to the body, extra width to account for different helmet sizes and raised chest to yellow-fluouce hyper-flexion
Innovative quick-release locking system for rapid and efficient fitting / removal offers secure and convenient closure
Compressed EVA foam compound padding to distribute the impact force over the widest area, yet remain lightweight
Colors: Black / Yellow Fluo, Black / Gray
Sizes: X-Small / Small, Large / X-Large
