01. Progressive performance
Engine
Advanced engineering techniques are used to build the engine to ensure maximum performance. It is then positioned in the frame to assist with the anti-squat behaviour from the chassis while also helping to centralise mass. Lightweight at just 29 kg, the 450 cc 4-stroke engine is also powerful with a peak power output.
Cylinder head
The SOHC cylinder head is incredibly compact and lightweight with the camshaft positioned as close to the centre of gravity as possible. 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 optimised for maximum torque and a smooth power delivery.
Cylinder and piston
The lightweight aluminium 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 anodised 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 centralise engine mass, the shaft arrangements are precisely positioned to harness rotating masses at the ideal centre of gravity.
Throttle body
The FE 450 features a 42 mm Keihin throttle body optimised 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 aluminium and stylishly finished with a black coating to highlight its premium quality.
