Specifically engineered for the 2017-2019 KTM 350 EXC-F and Husqvarna FE350, this Pro Series forged kit is the professional choice for maintaining \"Factory Quality\" power and long-range reliability. At Moto-House MX, we know that 350cc riders demand a perfect balance of lightweight agility and high-RPM durability; Wossner’s aerospace-grade forging delivers the strength required for both technical trails and open-road touring.\u003c\/p\u003e\n\n\u003cp\u003eForged from aerospace-grade aluminum alloy, the 8941DA features a reliable 12.5:1 compression ratio, providing crisp power delivery and smooth acceleration across the entire powerband. This kit incorporates advanced radial boss machining and enhanced oiling slots for superior wrist pin lubrication—a vital feature for the high-revving nature of modern 4-stroke engines. The permanent skirt coating reduces internal friction and piston rock, resulting in a quieter engine and a more efficient break-in period.
