A durable, fine-punched cam chain and Diamond-Like Carbon (DLC) coated rocker arm offer optimal efficiency and reliability with a single oil spray jet providing effective cooling. Valve timings are optimized for maximum torque and a smooth power delivery.
• CYLINDER AND PISTON: The lightweight aluminum cylinder is an engineering masterpiece with a 95 mm bore and a stroke of 63.40 mm. 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: With an optimized 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, metallic blue 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.
• 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 and designed with a calculated level of rigidity. To further complement and optimize the flex characteristics of the chassis, a 22 mm rear wheel axle is utilized. A durable chain slider is neatly integrated into the swingarm, ensuring uninterrupted forward momentum through deeply rutted corners.
