Vertex Piston Kit
DB Electrical is proud to offer genuine Vertex Top End Piston Kits. Vertex is recognized as offering the industry’s most comprehensive and performance-driven line of mechanical parts for powersports vehicles.
Vertex Piston Kits are based on the idea that you should spend less time repairing and more time riding. That’s why these kits contain all the components you’ll need to complete a specific type of repair. Why waste time sourcing a part here and a part there when you can get everything in one convenient kit? The Vertex team of experts sources all the parts you’ll need to complete the repair and get back in action.
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.
