With titles in the MX2 World Championship and AMA Supercross series to its name, the FC 250 is recognised as a highly competitive machine. Designed for motocross racing at every level, each component is selected for its performance and durability. Riders can take advantage of cutting-edge technology to gain an edge over their rivals with Traction Control, a Quickshifter, and a choice of engine maps elevating the on-track experience. Its compact and powerful DOHC engine plays a vital role in how the FC 250 handles, as its placement within the chromium molybdenum frame centralises mass to enhance agility. Completing the build, quality parts from WP, D.I.D, Dunlop, ProTaper, Twin Air, and ODI highlight the premium specification of the FC 250.
Faster and wiser
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.
Crankcases
The FC 250 crankcases are designed to optimise mass centralisation by housing all internal components in the ideal position to achieve the perfect centre of gravity. Manufactured using a high-pressure die-cast production process, the result is a thin, exceptionally strong wall thickness at the lowest possible weight.
DS clutch
The FC 250 features a highly reliable diaphragm steel (DS) clutch. Engineered from a single piece of CNC-machined steel, the clutch basket allows the use of thin steel liners, which contribute to the compact overall design of the engine. Underlining just how strong and durable the clutch is, the same components are used inside the much more powerful FC 450 engine.
Gearbox
Produced by Pankl Racing Systems, the 5-speed gearbox is designed to be extremely light and durable while featuring optimised and proven motocross-specific gear ratios (24:72). Integrated into the shift drum, a Quickshifter sensor can be activated by pressing the QS marked button on the Map Select Switch to further aid smooth upshifting.
Ride easier
Lightweight frame
With an optimised distribution of material around the steering head and upper shock mount, the frame delivers confidence-inspiring handling and assured stability when entering corners. To complement the overall look of the machine, the chromium molybdenum chassis is finished with a premium, white powder coating. The finishing touches are the frame protectors, which not only protect the paintwork, but also provide riders with additional grip, even in the toughest conditions.
Polyamide-reinforced aluminium subframe
Made from 60% polyamide and 40% aluminium, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 1.8 kg. The lower subframe spars and frame mounts are manufactured from cast aluminium for significantly improved reliability. The upper section of the subframe is made from injection-moulded polyamide to enable specific flex characteristics and ensure a lightweight construction.
CNC machined triple clamps
Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps ensure precisely calculated geometry for increased stability. Handlebar flex can be customised with the handlebar clamp that offers two mounting options - rubber-damped for less vibration, or fixed for enhanced front-end feedback. The upper triple clamp is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling.
WP XACT front suspension
Rigorously tested by the WP research and development department, the 48 mm WP XACT closed cartridge spring forks fitted to the FC 250 provide exceptional comfort. Inside the forks, mid-valve pistons optimise oil flow and prevent foaming for consistent and predictable damping at all times. A hydrostop, active in the final 40 mm of travel, reduces the impact of harsh and high-speed landings to maintain forward momentum. Both compression and rebound settings can be quickly adjusted by hand using the easily accessible clickers located on top of each fork leg.
WP XACT shock absorber
The WP XACT rear shock features a Computational Fluid Dynamics (CFD) optimised main piston, ensuring superior initial comfort and predictable performance in all conditions. To give riders the option of creating a personalised set-up, rebound, as well as the high and low-speed compression settings, can all be adjusted easily by hand.
Swingarm
The swingarm is manufactured using a die-cast production process and designed with a calculated level of rigidity. To further complement and optimise the flex characteristics of the chassis, a 22 mm rear wheel axle is utilised. A durable chain slider is neatly integrated into the swingarm, ensuring uninterrupted forward momentum through deeply rutted corners.
