This is the TBM Signature Series ride Plate for the SXR 1500. This is not just some worked over plate from the past. TBM has taken the time to map the bottom of the ski and to provide a plate that takes into account all conditions that a rider will face from smooth high-speed runs without the speed wobbles to the racecourse chop. This plate is 1-inch longer and incorporates a dual chine/concave design with steeper transitions from the hull contours to the planing surface of the ride plate. The planing angle has been manipulated to get this ski to stay planted in rough water, while not overdoing it to where the nose wants to sub entering a corner. TBM reports an average top speed increase of 1.5 mph using this plate. Finally, it is constructed from aircraft-grade alloy, trued and heat-treated and the mounting holes are CNC machined to fit without any modification. They are finished with satin black powder coating and new stainless steel hardware is provided.
