Description

Wiseco offers Black Edition V-Twin piston kits for a wide range of Harley-Davidson® street bikes. They feature forged aluminum pistons with ArmorX coating for reduced wear and superior protection in extreme conditions. An ArmorFit skirt coating auto-adjusts to the cylinder wall (so there's no need to measure clearance), providing smooth, quiet, trouble-free operation. The pistons are available in a variety of bore sizes and other options. Order the kit recommended for your motorcycle.

Additional product details:

* Dome design for improved flame travel to maximize air/fuel burn efficiency
* High compression (11:1) for added power
* Superfinish piston pin reduces friction and improves scuff resistance
* Enhanced pin oiling for improved lubrication and reduced friction
* Augmented ring land details improve ring seal and function
* Dedicated rings for precise fit, improved compression, and oil control
* Kits include two pistons, rings, piston pins, and circlips
