The Forged Pistons 883 To 1200 10.5:1 .020 are a high-performance upgrade for Harley Davidson Sportster 883 models, designed to enhance engine power and durability. These KB forged pistons are meticulously crafted from 4032 forged alloy with an 11% silicon content, ensuring superior strength and resistance to cracking under extreme conditions like detonation or pre-ignition.

The manufacturing process involves forming the pistons in a forging press and then fully machining them to precise specifications. This results in pistons that are not only durable but also lightweight, reducing overall engine weight and improving performance. The pistons are specifically designed for Street or Race applications, making them ideal for riders looking to boost their bike’s power with NOS or turbochargers.

One of the standout features of these forged pistons is the coated skirts, which reduce friction and wear, extending the lifespan of the pistons and improving overall engine efficiency. This coating also helps with heat dissipation, keeping the pistons cool even under high-performance conditions.
