ABSTRACT:
A snowmobile ski flexing apparatus comprises a flexible snowmobile ski with a curved front portion and a flexible elongate loop attached at a first end to the front portion of the ski and bending upward and rearward and then down upon the ski to abut it at a second end at approximately its midpoint. A retainer comprising a chain is secured at one end to the ski at its front portion, while its other end is slidably engaged to the loop, allowing the latter to move lengthwise relative to the ski. A tubular sleeve with rectangular cross-section circumscribes the loop near the second end thereof and allows sliding movement of the loop when the ski is flexed, allowing flexing of a large portion of the ski and acting as a shock absorber.
