Exceptional strength at the lowest possible weight, and with visible chain adjuster marks to make chain adjustment quick and accurate. Our hollow, die-cast swingarms deliver durability and precision.
Make no mistake about it, the MC 450F rips! But thanks to centralization being key to the compact SOHC motor's design, the 62hp power unit is positioned more centrally within the frame, ensuring a positive effect on the bike's overall handling. It weighs just 27.3kg, including the electric starter!
CYLINDER HEAD AND BALANCER SHAFT
The EX 450F cylinder head is compact, lightweight and benefits from a short profile that locates the single camshaft as close to the center of gravity as possible. Why? To significantly improve the handling. With lightweight 40mm intake and 33mm exhaust valves activated by rocker arms coated in a low-friction Diamond Like Coating (DLC), the SOHC cylinder head produces both torque and precise throttle response.
CYLINDER & PISTON
Essential to the EX 450F producing strong, smooth power is the lightweight aluminum cylinder and CP bridged-box-type piston, which only weighs 320g. Combined they ensure the motor pumps out an impressive 62hp while also helping to reduce vibrations.
The 5-speed transmission fitted inside the EX 450F motor ensures smooth and precise shifting and is designed to be extremely light and durable while delivering maximum power from the engine to the rear wheel. The shifting fork has a low-friction coating for smoother gear changes while the gear lever is designed to prevent dirt build-up and ensure perfect gear selection in all conditions
The EX 450F crankshaft is key to the motor delivering great traction and enhanced rideability. It also helps give the bike its agile handling. Benefitting from long service intervals of 100 hours (who doesn’t like those?) a plain big end bearing comprising of two force-fitted bearing shells that ensure maximum reliability and durability.
Our high-pressure die cast production process guarantees two things - reliability while keeping overall crankcase weight down. Designed so that the internal moving shafts and parts are carefully positioned, the EX 450F offers best possible handling.
Ensuring cross country specific power, our EX exhaust systems are designed to deliver the highest possible quality. The EX 250F, EX 350F and EX 450F exhaust systems are designed using an innovative 3D hydroforming process to ensure the best performance and lowest weight as well as a 2-part header pipe, which allows it to be removed without having to take out the rear shock. Further innovation allows for a short, compact silencer that doesn't increase noise levels.
Controlling the awesome power of the EX 450F is key! That's why the bike features a lightweight Dampened Diaphragm Steel (DSS) clutch. Using a single diaphragm steel pressure plate instead of traditional coil springs, together with a damping system the clutch delivers better traction and durability allow riders to have full and complete control.
