2023 450 EXC-F
2023 KTM 450 EXC-F for Sale at Ultimate KTM Gold Coast in Biggera Waters, QLD | Specifications and Review Information
MASTER OF TRAILS
With impressive and efficient performance, a lightweight frame and subframe, race-proven bodywork and ergonomics, a compact exhaust system as well as exceptional cooling and suspension, the KTM 450 EXC-F is sure to remain the benchmark for all others to follow.
Engine
Combining compact dimensions with immense power output, this 449.9 cc fuel-injected SOHC powerplant is the most powerful and refined on the market. Its class-leading power delivery is available throughout the entire rev range and with its low weight of only 29.2 kilograms, it's also one of the lightest 450 cc mills out there.
Cyclinder Head
The KTM 450 EXC-F engine is fitted with a compact SOHC cylinder head for optimal mass centralization. The head configuration promises efficient power delivery and unrivaled performance. A single overhead camshaft also ensures optimal gas flow, with low-friction rocker arms and timing chain guides guarantee consistent performance throughout the rpm range.
Crankshaft
Located in an ideal position close to the center of gravity, The KTM 450 EXC-F crankshaft contributes to easier handling. It utilizes a short connecting rod, which makes for an overall compact and lightweight engine. The engine's pressurized lubrication system provides the necessary oil feed for the big end bearing. This design has a direct benefit for the crankshaft with extended service intervals. So just pin it, all day long.
Crankcases and engine covers
A lightweight engine case design allows for a very centralized shaft configuration while contributing to an efficient centralization of mass. Additionally, the engine covers feature a smart surface structure that reduces the wear caused by the rider's boots, keeping them looking as fresh as the day it rolled off the production line, while a reinforced clutch cover and engine guard mean the engine case is more robust.
Cooling
Keeping the engine cool when the going gets tough comes courtesy of a pair of radiators, mounted close to the center of gravity. These make use of CFD technology (Computational Fluid Dynamics) and clever coolant circuit routing, achieving optimum engine temperature for the highest performance, in all conditions. Above all, the delta distributor, integrated into the frame triangle, features a large center tube for highly efficient coolant flow, as well as radiator fan.
Exhaust
Packing a punch and delivering an unmistakable engine note, all 4-stroke KTM EXC models feature an easy-access two-piece header pipe that can be disassembled easily to allow access to the rear shock. An aluminum muffler sleeve has a short and compact profile.
Swingarm
The KTM 450 EXC-F features a one-piece aluminum swingarm, which is manufactured using a gravity die-cast production process. This results in exceptional strength at the lowest possible weight and the perfect flex behavior.
Footpegs
Self-cleaning footpegs prevent mud from clogging up the pegs, even when dragging them through deep ruts. This means your boots maintain their grip, and you maintain your focus on the trail.
