Wiseco Racer Elite Piston Kit 66.4mm RE916M06640-1113

Using several different proprietary coatings, along with high-strength materials and precision machining equipment, Wiseco has created a new series of pistons. Appropriately named the Racer Elite 2-Stroke Series, these pistons are stronger, perform better, and last longer. The challenge in replacing a piston comes in choosing the proper size piston for the dimensions of the bikes cylinder. Fortunately, Wiseco has taken the micrometer out of the equation with the Racer Elite 2-Stroke Series pistons. The secret is ArmorFit a proprietary skirt coating that allows the piston to self-adjust to the cylinder. The Racer Elite 2-Stroke Series pistons have enough clearance for the smallest cylinder, adequate clearance for the largest cylinder, and everything in between.
