Vertex Pistons - 24212B - KTM - 85 SX - Cast Replica - Piston and Ring Kit
Vertex Piston Kit offers state-of-the-art, high-quality pistons for nearly any powersport use. Vertex is the choice of enthusiasts who seek optimal performance in any powersport application. Pistons are available for 2-stroke and 4-stroke applications. 2-stroke pistons have an 18% silicon content which decreases wear and thermal expansion, allowing for tighter running tolerances for more power, less noise and longer lifespan. 4-stroke pistons are forged from either 2618 or 3032 alloys for superior strength and durability. Exact fit A, B, or C pistons match your cylinder bore perfectly to maximize power and performance while reducing blow-by and oil consumption. High-tech Molybdenum Disulphide (MOS2) skirt coating for reduced wear and improved break-in. All piston kits include piston, rings, wrist pin, and circlips. Cast and Forged Replica pistons are OE replacements with stock OE compression ratios. Cast and Forged Race pistons are unique with only one compression ring. Forged Hi-Comp pistons increase compression and power over Replica pistons. Forged GP Racer's Choice pistons have T-box forgings, unique dome profiles, surface treatments and increased compression ratios to produce more power, strength, and durability. Big Bore pistons increase displacement and power while maintaining stock compression ratios.
