Widely praised as the best performing 250 cc 4-stroke on the market, the FC 250 retains its position at the head of the field. A compact and powerful engine is housed inside in an updated chromium molybdenum frame that is lower in weight and offers improved chassis flex. Updates to the WP suspension and rear shock linkage ensures the outstanding agility of the FC 250 is enhanced further for 2025. Its new bodywork offers refined ergonomics for effortless movement and control, with striking white and blue graphics applied using in-mold technology for an outstanding and long-lasting finish.
Engine
Engineered to ensure class-leading performance and handling characteristics, all major engine components and shaft arrangements are carefully positioned closer to the centre of gravity to reduce the effects of rotational inertia. The 250 cc 4-stroke 47 hp engine is also considerably light and tips the scales at just over 26 kg. The FC 250 engine remains remarkably powerful with an increased power output and impressive torque to suit riders of all abilities.
DOHC cylinder head
Featuring finger followers treated with a diamond-like carbon (DLC) coating, the DOHC cylinder head is engineered for high-level performance and unrivalled durability. The titanium intake valves are 32.5 mm while the exhaust valves are 27.5 mm for optimised gas flow. The FC 250 revs freely, and produces strong and efficient power throughout the rev range up to its 14,000 rpm limit.
Cylinder and piston
The 81 mm cylinder houses a forged bridged-box-type piston made by CP, which weighs just 150 g. High strength aluminium is used to manufacture both the cylinder and piston, with both components professionally engineered for outstanding performance and reliability. The stroke is 48.5 mm to match the resized cylinder, which creates a compression ratio of 14.5:1 for exceptional torque and peak performance.
Lightweight frame
For 2025, the frame around the shock mount and steering head has less material, with revised wall thickness in higher stress areas improving overall strength. Together, these changes reduce the weight of the frame by 300 g for improved cornering, unparalleled rider feedback, and energy absorption. New engine mounts with cut-outs improve chassis flex characteristics, reduce weight, and contribute to confidence inspiring stability. The frame is finished with a premium metallic blue powder coating with frame protectors offering superior protection, durability, and grip in any condition.
Functional bodywork
The new bodywork has been designed to allow riders to perform at their very best for extended periods of time. Following countless hours of testing and refinements, the larger contact points and surfaces in the rider triangle enhance comfort, which in turn helps to reduce fatigue. A higher, wider seat offers unrestricted movement with revised tank shrouds and a high grip cover ensuring riders stay firmly in place under hard acceleration.
Airbox
A stiffer, one-piece airbox design with an optimised air intake reduces air deformation, ensuring an unrestricted flow of air and maximum filter protection. The Twin Air filter is easily accessed without tools, by simply removing the left side panel for easy maintenance.
Hydraulic clutch
The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in every condition. With this hydraulic system, free play is constantly compensated so that the pressure point and function of the clutch remain identical in cold or hot conditions, as well as over time. Countless hours of race-focused testing have proven the exceptional reliability of the high-quality, Brembo hydraulic systems.
Wheels and tyres
Assembled with CNC-machined hubs, lightweight spokes, and strong, black-anodised alloy rims by D.I.D, the wheels of the FC 250 offer strength and minimal unsprung weight. New, Dunlop Geomax MX34 Motocross tyres are fitted and feature a proven block-within-a-block design for enhanced control and superior grip on a variety of riding surfaces.
