( Brand: Vertex Pistons ), ( Manufacturer Part Number: 22991A ), ( Part Type: Piston )
Introducing the Vertex Pistons 22991A piston, specifically designed for KTM 105 SX motorcycles manufactured between 2004 and 2011 with a 95mm bore size. This high-performance piston is an excellent upgrade for those looking to enhance their engine's power output and efficiency.
The Vertex piston is made from a high-grade forged aluminum alloy, providing superior strength and durability compared to its cast counterparts. Forged pistons undergo a more intricate manufacturing process, resulting in a more uniform structure and reduced weight. This contributes to greater power delivery, better ring seal, and a longer service life.
Equipped with a Nikhil DLC (Diamond Like Carbon) coating on the piston skirt, the piston offers improved cylinder wall protection from scratches and scoring. This coating reduces friction and provides excellent exhaust gas sealing, while also allowing for easier engine start-up and smoother operation.
The combustion chamber of the Vertex piston features a modern, optimized design, which increases gas flow and improves the overall engine performance. This results in better throttle response, increased power output, and better fuel efficiency.
Each Vertex piston undergoes rigorous testing to ensure perfect fitment and optimal performance. The piston is precision machined to exacting tolerances and checked for concentricity, roundness, and ring gaps. Additionally, Vertex offers comprehensive piston kits that include rings, clips, etc., making engine rebuilds or upgrades a more convenient process.
In summary, the Vertex Pistons 22991A is an exceptional choice for KTM 105 SX owners seeking to boost power, enhance efficiency, and improve engine durability. It not only offers state-of-the-art design and superior materials but also comes with the confidence that it has undergone meticulous testing and quality control.
