2017 Husqvarna FC250

Husqvarna just released its 2017 motocross models.
FC 250
The 250cc DOHC engine has been designed in conjunction with the chassis to operate in perfect harmony. All internal components have been engineered to deliver the maximum possible performance and packaged in order to position the engine at the ideal center of gravity within the chromoly steel frame. In combination with the carbon fiber rear subframe and new WP AER 48 fork, the FC 250 is one of the most technologically advanced 250 4-stroke motocrossers developed to date.
Engine
All major components and shaft arrangements have been carefully designed and placed in specific positions that best suit the performance and handling characteristics of the overall package. The 250 cc engine is not only light at 57.5 lbs but also remarkably powerful with an overall power output of 46 hp at the output shaft. In order to achieve this, all components are engineered to produce the least amount of friction possible reducing drag as a result.
 Engine design → light and compact for optimized mass-centralization
 Outstanding performance → 46 hp peak power and 14,000 rpm rev-limit
 Low friction → reduces overall drag
Cylinder head
While keeping the same structural integrity
 Large titanium valves (32.5 mm intake, 26.5 mm exhaust) → optimal intake and exhuast flow
 Finger followers with DLC coating → reduced friction, better performance
 Carefully designed combustion chamber → optimal power throughout the rev-range
Cylinder and piston
The 78mm bore cylinder houses a forged bridged-box-type piston made by CP. Both the cylinder and piston are professionally engineered from high strength aluminum resulting in outstanding performance and reliability. The compression ratio is 14.4:1.
 Large 78mm bore and large diameter valves → high-revving, quick response
 Forged box-type → high performance and reliability
Crankshaft
The crankshaft is designed to offer the best possible performance all while being placed in the perfect position to centralize oscillating masses for optimal handling. The plain big end bearing features two force-fitted bearing shells ensuring maximum reliability and durability guaranteeing long service intervals of 100 hours.
