Vertex Piston Kit, 44.97 mm for Husqvarna CR65 and KTM 65 SX (22481CD)

Upgrade your two-stroke engine with the VERTEX 22481CD Piston Kit, engineered as a cast OE replacement for Husqvarna CR65 and KTM 65 SX applications. This kit is designed to support dependable engine performance, consistent operation, and a practical replacement solution for routine maintenance or engine rebuilding. The piston is manufactured from gravity-cast aluminum alloy with an 18% silicone content, providing a durable foundation suited to demanding off-road riding conditions.
The piston receives a T-5 heat-treatment cycle that combines hardening and tempering to improve material strength and durability. Its skirt is coated with a high-tech molybdenum disulfide coating, which helps reduce friction during initial operation, promotes faster break-in, and supports extended piston life. This coating works with the piston’s precision construction to help maintain smooth movement within the cylinder while supporting reliable engine service.
The VERTEX 22481CD kit includes the essential components for installation, including the piston, piston rings, wrist pin, and circlips. As a complete replacement package, it helps simplify the rebuilding process and ensures the primary piston hardware is included together. Verify application and engine specifications before installation to ensure proper fitment for your Husqvarna CR65 or KTM 65 SX.
Designed for riders, technicians, and engine builders seeking a dependable OE-style replacement, this VERTEX piston kit combines treated cast aluminum construction with a low-friction skirt coating. Follow the engine manufacturer’s service procedures for inspection, clearance measurement, ring installation, break-in, and final assembly.
