Inside, the forged CP bridged-box-type piston features anodized annular grooves for added durability and extended service intervals. The compression ratio remains unchanged at 12.75:1.
• CRANKCASES: Designed to be low in weight without sacrificing strength or reliability, the crankcases are made using a high-pressure die cast production process to create a thin-wall design. To centralize engine mass, the shaft arrangements are precisely positioned to harness rotating masses at the ideal center of gravity.
• THROTTLE BODY: The FE 450 features a 42 mm Keihin throttle body optimized for throttle response. The injector is positioned to ensure the most efficient flow into the combustion chamber with the throttle cable mounted directly without a linkage for an enhanced response.
• EXHAUST: The exhaust system is expertly designed to deliver class-leading performance at the lowest possible weight with the header pipe manufactured in two pieces. This design allows the header pipe to be removed without having to remove the rear shock. Further innovation allows for a short, compact silencer without increasing sound levels. The silencer is crafted from lightweight aluminum and stylishly finished with a black coating to highlight its premium quality.

State-of-the-art chassis

• FRAME: A proven chromium molybdenum steel frame ensures straight-line stability at speed without sacrificing agility through the slow and technical sections. Optimized wall thickness throughout the chassis aids durability, in addition to providing unparalleled rider feedback and energy absorption. For an optimized level of anti-squat behavior and overall chassis balance, the shock is not directly connected to the main tube. The frame is complete with a premium metallic blue powder coating with frame protectors offering improved grip in all conditions.
• HYBRID SUBFRAME: Made from 60% polyamide and 40% aluminum, the subframe offers exceptional strength and durability at a low overall weight of just 3.9 lb (1.8 kg). The lower subframe spars and frame mounts are manufactured from cast aluminum for reliability with the upper section made from injection-molded polyamide to enable specific flex characteristics.
• SWINGARM: The swingarm is manufactured using a die-cast production process for optimal rigidity. To match the flex characteristics of the chassis, a 22 mm rear axle is utilized. Additionally, the swingarm is designed to enhance the durability of the chain glider while the chain guide features a rounded profile that makes it less prone to catching on external objects.
• BODYWORK: Adorned with clean, Swedish-inspired graphics, the bodywork is designed to allow riders to perform at their best for extended periods of time. A flat seat profile offers unrestricted movement with a new, high grip cover ensuring riders stay firmly in place under hard acceleration. Above the side panels, recessed pockets allow for the machine to be lifted and moved, which is particularly beneficial for those competing in extreme enduro events.
• RADIATORS: Manufactured from high-strength aluminum, the radiators are designed using Computational Fluid Dynamics (CFD) to channel air through them in the most effective way. A large center tube channels coolant through the frame to reduce pressure at this point in the system for a more consistent flow. An internal thermostat enhances reliability while the radiator cap features a bayonet style closure for a secure fitment.
• FUELTANK: A 2.1 gallon (8.0 liter) fuel tank integrates neatly with the ergonomic bodywork and features a robust rubber cushion beneath it to hold the tank in place and protect the frame from wear. The one-piece fuel pump design and integrated filter allows the tank to be emptied further, which is particularly beneficial during longer events. For durability, the external fuel line is specifically routed to make it less exposed and susceptible to damage.

Technology advanced

• LED HEADLIGHT: The LED headlight provides a remarkably bright light output for excellent visibility at night and is particularly effective when riding through dense woodland. A clever mounting design sees the LED lighting unit fitted inside the headlight mask using a quick-release system that allows it to be replaced quickly and easily if damaged.
• MAP SELECT SWITCH: Designed for easy operation, the Map Select Switch allows riders to easily choose between two EFI maps, activates Traction Control, and engages the Quickshifter. Traction Control can be switched on or off via the Map Select Switch and functions by analyzing throttle input from the rider and the rate at which the engine RPM increases. If the RPM increases too quickly, the EMS registers a loss of grip and reduces the amount of power to the rear wheel, ensuring maximum traction. The Quickshifter can also be engaged using the same Map Select Switch and offers seamless upshifts under heavy load.
• QUICKSHIFT: The Quickshifter can be activated or deactivated via the Map Select Switch. By interrupting the ignition for a fraction of a second, this allows upshifting while the throttle is fully open without the use of the clutch. The Quickshifter is only active from second gear upwards.
