The Alpinestars Tech-Air Race Airbag System is the result of 15+ years of extensive safety research and development. Tech-Air is the only proactive, independent airbag system on the market - no GPS, tethers, or on-bike sensors needed. MSRP $1,149.95 The Tech-Air Race Airbag System utilizes electronic sensors that communicate with the Airbag Control Unit (ACU). This allows the system to be proactive, providing protection prior to the first impact in a crash. When inflated, Tech-Air Race provides full upper body protection for the back shoulders, kidney area, chest, and upper abdomen. The ACU is seal-protected inside a CE level 2 back protector, allowing all-weather use. Tech-Air Race is certified to function between -10°C and 50°C. The Tech-Air Race system comes pre-loaded with the Race firmware, which is optimized from MotoGP. The Race firmware allows the system to have two separate deployments on the track. The Tech-Air Race system can be configured to run the Street firmware, which is optimized for use on the street. The Tech-Air Race system will fully deploy in 45 milliseconds and stay fully inflated for 5 seconds, then begin to deflate on its own. This system uses a certified lithium-ion battery, with a battery life of 25 hours and a full recharge time of approximately 6 hours. One hour of charge equals approximately 4 hours of protection. Tech-Air Race has dual charge capability for sizes M-XL and single charge capability for 2XL garments. The main shell has a multi-material construction of Lycra, Cordura, and 2D mesh.
