The ProX Piston Kit is a high-quality replacement for the OEM piston in 2003-2007 KTM 450 EXC motorcycles and 2008-2009 KTM 450 XC ATVs. With a bore size of 88.96mm and a compression ratio of 11.0:1, this piston kit is designed to meet OEM specifications while offering a cost-effective alternative. Manufactured by reputable OEM suppliers, ProX pistons are precision-machined using advanced CNC technology and made from a low-expansion, low-friction alloy used by major Japanese engine manufacturers. The kit includes the piston, piston rings, wrist pin, and circlips, providing everything needed for installation. ProX offers standard and oversized piston options, allowing for proper piston-to-cylinder wall clearances and extending the lifespan of both sleeved and plated cylinders. This makes it a reliable choice for maintaining or rebuilding your engine while ensuring durability and performance.
