The Story
This Black Diamond™ Stainless Steel Exhaust Valve is built for KTM® SX-F and XC-F 250 models from 2013 to 2015. Engineered from a one-piece forging, it features a nitrided surface treatment for enhanced wear resistance and reduced friction. Developed with advanced Finite Element Analysis and flow bench testing, this valve ensures reliable performance under high-stress engine conditions. Use of KPMI Lightweight Valve Spring Kits is required for proper installation and function.
