The 250cc DOHC engine is designed in conjunction with the chassis to operate in perfect harmony. All internal components are engineered to deliver the maximum possible performance and packaged to position the engine at the ideal centre of gravity within the chromoly steel frame. The addition of a carbon fibre composite subframe and WP AER48 fork, the FC 250 is one of the most technologically advanced 250 4T motocrossers available on track.
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 FC 250. The 250 cc engine is not only light at 26.1 kg but also remarkably powerful with an overall power output of 46 hp at the output shaft. One way in which this was achieved was by engineering key components to produce the least amount of friction possible, reducing drag as a result.
DOHC cylinder head
The DOHC cylinder head features finger followers with a DLC (diamond like carbon) coating resulting in minimal friction and optimal performance. These actuate large titanium valves (32.5 mm intake, 26.5 mm exhaust) which at the 14,000 rpm rev-limit open and close multiple times each second introducing fuel/air mixture to the carefully designed combustion chamber delivering efficient and optimal power throughout the rev-range.
The FC 250 exhaust system has been expertly designed to deliver the best possible performance while adhering to the FIM noise limits. The header pipe features a resonance chambers for optimal performance while the silencer is crafted from lightweight and strong aluminium.
