Attention watercraft enthusiasts and mechanics! This Wiseco 85.00mm 2-stroke piston is built for serious performance and durability. What makes it special? It's forged from high-silicon, low-expansion aluminum that offers superior strength while being lighter weight. That means better heat transfer and longer life for your engine. The diamond-turned finish from CNC computer-controlled manufacturing ensures perfect sizing every time - no variations that can cause issues. The coolest part? You can install these pistons in any cylinder bore composition - cast iron, chrome, nikasil, or boron composite - with complete confidence. Need oversize options? Wiseco's got you covered with a wide range that can extend the life of cast iron lined cylinders. Even if you have chrome or other composite cylinders, replacement sleeves are available to work with these pistons. The manufacturing process is state-of-the-art computerized, making these some of the finest forged pistons available for both high-performance racers and recreational riders. Availability is great too - with three warehouse locations, most orders ship quickly, and even special orders typically arrive within 2-3 business days.
