A deflectable component for a motorized vehicle can include a deflectable part formed at least partially from a superelastic and or shape memory material, wherein at least a portion of the deflectable component is moved to a deflected position upon application of a threshold force when moving at or above a predetermined speed, and returning to an undeflected position when moving below the predetermined speed. The deflectable component may comprise a connection link fabricated at least partially from a superelastic and/or shape memory material to tailor the flex point characteristics of a connected surface to a desired response. The deflectable component may improve the performance of motorized vehicles by improving the aerodynamic and fuel efficiency, as well as other beneficial effects.
