Carrillo M4027 High-Performance Piston Kit for Kawasaki KFX 450

The Carrillo M4027 is a high-performance piston kit designed for the 2008-2014 Kawasaki KFX 450 ATV. This kit features CP-Carrillo's advanced Project X Pro piston technology, engineered to deliver exceptional durability and performance in demanding powersports applications.

Key Features:

• 96mm standard bore diameter with 13.0:1 compression ratio for optimized power delivery
• Advanced pin bore technology that reduces stress concentrations and allows the wrist pin to flex naturally
• Proprietary manufacturing process developed and tested with high-end OE companies
• Significantly increased durability compared to conventional pistons through stress reduction in critical areas
• Precision-engineered to meet or exceed horsepower requirements while improving longevity

CP-Carrillo's specialized pin bore treatment process represents years of research and development with leading manufacturers. Rather than traditional honing, this technology uses specific machining processes to create optimized internal geometries that dramatically reduce stress in one of the most critical areas of the piston. This proven technology, previously reserved for high-end racing applications, delivers professional-grade performance and reliability for serious riders.
