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 8211 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 Functional Bodywork The ergonomic bodywork was designed to ensure that riders can perform at their best throughout every race This was achieved through extensive testing with the smooth contact points in the rider triangle allowing racers to grip the machine tightly with their legs reducing fatigue The radiator shrouds featuring in mould graphics contribute to the progressive appearance of the machine while a tall wide seat offers unrestricted movement A high grip seat cover also helps keep riders securely in place under hard acceleration Airbox A one piece airbox optimises air intake by reducing deformation This design provides an unrestricted flow of air for maximum power without compromising filter protection The Twin Air filter can be easily inspected without tools by simply removing the left side panel 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 Hydraulic Brakes Class leading Brembo brake callipers made from single pieces of aluminium for strength are fitted front and rear to ensure high braking performance Together with 260 mm front and 220 mm rear discs both designed to prevent mud build up effective stopping power in all conditions is assured The rear brake pedal is highly durable and less susceptible to damage when riding through deep ruts ProTaper handlebar Developed between Husqvarna Motorcycles and leading handlebar manufacturer ProTaper the exclusive bend offers superior comfort class leading strength and fatigue resistance at the lowest possible weight ODI Grips ODI lock on
