Alta engineers have re-imagined the ideal off-road subframe structure: strong, light, durable, and comfortable. Without a need to combat hot exhaust systems, the core of Alta's subframe could be made of Makroblend®, a resin engineered for exceptional durability. The Airframe allows the system to be compliant for rider comfort, and to bounce back rather than bend or break in a crash. To achieve a more efficient (i.e. lighter, stronger) structure, we designed a system of internal ribs and a stressed skin similar to that of an airplane fuselage. The Redshift Airframe performs with multiple times the strength of a standard aluminum or polymer subframe.
