Introducing the WiseCo 2945-W261731-65 piston kit, specifically designed for the 1993-1995 Harley-Davidson Touring models with an 889cc big bore engine. This high-performance piston kit offers an impressive 5.00mm increase in piston diameter and a 74.50mm stroke length, delivering enhanced power and torque.

The piston pins are made from high-strength, heat-treated steel, ensuring they can handle the increased power and torque produced by the larger pistons. Each pin is also nitrided for superior strength and durability, and features a unique pin retaining design that ensures a secure fit and easy installation.

With this WiseCo piston kit, you can expect improved engine performance, increased power and torque, and enhanced durability. It is designed to be a direct replacement for your stock pistons, making the installation process straightforward and hassle-free. This kit is an excellent choice for riders who demand the best from their Harley-Davidson Touring engine and are looking to take their performance to the next level.
