The Wiseco 746M4500 piston kit is specifically designed for KTM 65 SX and XC models produced between the years 2000 and 2008. This piston kit is an excellent upgrade solution for riders seeking improved engine performance, durability, and reliability.
The Wiseco piston kit includes two high-quality, forged pistons made from aerospace-grade 2618-T6 aluminum alloy. Forged pistons are stronger and more durable than cast pistons due to their uniform density and precise dimensions. The piston crowns are finished with a unique transmission oil cooled skirt coating, providing an excellent thermal barrier between the cylinder walls and the piston, reducing friction and increasing longevity.
The piston kit features a compression height of 45mm and a piston weight of approximately 235 grams, which contributes to a slight increase in compression ratio, enhancing engine power and torque delivery. The pistons are alloy skirts with a full floating wrist pin and a heavily ovalized piston shape, optimizing piston-to-ring contact and improving ring sealing.
This kit comes with ring packages custom-designed for the KTM 65 engine, ensuring optimal ring sealing and engine compression. The included piston rings are a nuclear alloy, CR girdle rings with a compression ring groove design, providing superior ring life and reduced engine blowby. The rings also feature a chamfered top ring compressor, making the ring installation process easier and more efficient.
Additionally, this Wiseco piston kit includes two SCAThonite steel connecting rods with tapered pins and ARP2000 rod bolts, ensuring a strong and reliable connection between the pistons and the crankshaft.
Overall, the Wiseco 746M4500 piston kit is an incredible performance enhancement for KTM 65 SX and XC motorcycles, delivering increased power, enhanced reliability, and improved durability. This product is a must-have for competitive riders and enthusiasts seeking to unlock their bike's full potential.
