Dominating the mid-range professional class, the Husqvarna 550 XP® Mark II is engineered for the relentless pace of modern forestry and high-end tree care. This is not just a revision; it is a ground-up redesign that delivers a staggering 20% increase in cooling capacity and best-in-class cutting speed compared to its closest rivals. Powered by a high-output 50.1cc X-Torq® engine, the 550 XP Mark II specializes in extreme acceleration, making it the most lethal tool in your arsenal for felling, limbing, and bucking small to medium-sized timber. With a slimmed-down, ergonomic chassis that minimizes gyroscopic forces, this saw moves with a fluidity that reduces operator fatigue during eight-hour shifts. When your livelihood depends on “pull-and-go” reliability and surgical precision, the 550 XP Mark II stands alone as the undisputed king of the 50cc category. Extreme Cooling Efficiency: Features a redesigned cylinder with 13% more cooling fin surface and a specialized heat shield that isolates the carburetor from engine heat, preventing “vapor lock” and ensuring easy hot-starts in the middle of a summer felling job. AutoTune™ 2.0 Intelligence: The onboard microprocessor automatically tunes the engine 10 times faster than previous versions. It compensates for fuel quality, altitude, and humidity in real-time, meaning you never touch a carburetor screw again. Best-In-Class Gyroscopic Balance: The outboard clutch design positions the guide bar closer to the center of gravity. This translates to significantly lower gyroscopic resistance, allowing you to “flick” the saw between branches during limbing with minimal wrist strain. X-Force™ Bar & X-Cut™ Chain Optimization: Factory-fitted with the SP33G X-Cut chain, which is pre-stretched and sharpened with a unique geometry that stays sharper up to 4x longer than standard chains under heavy sap conditions. RevBoost™ Instant Acceleration: Provides high-speed chain bursts specifically for limbing, giving you a near-instant transition from idle to peak cutting speed for cleaner, faster snedding. Magnesium “Battle-Ready” Crankcase: A professional-grade, high-pressure die-cast crankcase built to withstand the extreme RPMs (up to 10,200 rpm) required for sustained commercial forestry. Visible Fuel Monitoring: A wide, transparent fuel window allows for instant checks, preventing the “run-dry” stalls that interrupt your cutting rhythm.
