2022 450 SX-F KTM Powerful Dirt Bike – Features and Price

2022 450 SX-F KTM Powerful Dirt Bike

Engine and Exhaust


Regarding power delivery and ultimate performance, the exhaust system on all 4-stroke lineups plays a critical role and gives a powerful punch. It features a model-specific header pipe with an all-new FDH (Flow Design Header) advanced resonator and a tiny chamber surrounding the line. The design allows the disassembly of the exhaust without eliminating the shock absorber, as well as greater access to the shock. The new silencer’s interior design, which includes an aluminum sleeve, end cap, and internal structure, allows for thinner ergonomics, making the motorcycle seem smaller without compromising regulatory noise limitations.


Regarding KTM’s competitive motocross line, the 450 cc engine is the ultimate powerhouse. It has a single overhead camshaft cylinder head and is powered by the most up-to-date electronic injection system. It allows for a very effective distribution of the outstanding power over the rpm range. This type is still the lightest 450 cc engine on the MX market, even with its super-beneficial electronic starter.

Cylinder head

A lightweight, compact SOHC (single overhead camshaft) cylinder head is installed on the KTM 450 SX-F. The design emphasizes mass centralization, which helps to improve overall handling. The overhead camshaft’s surface is friction-optimized, and the valve timing is precise, resulting in exceptional responsiveness. The four ultra-lightweight titanium valves (intake 40 mm, exhaust 33 mm) are controlled by stiff rocker arms. The intake side rockers are DLC coated, enabling high engine speeds of 11,500 rpm. Low-friction chain guides further support the high RPM values. The revolutionary head shape ensures the most efficient delivery of unrivaled power, giving you a competitive advantage.


The KTM 450 SX-crankshaft F’s is positioned in an optimal location near the center of gravity, allowing for superior mass centralization. It has a short connecting rod, allowing for a more compact motor design and responsive power delivery. The machine is perfectly balanced, with just the right amount of inertia for maximum traction and ride ability. A simple large end bearing with two force-fitted shells runs directly on the crank pin, with the engine’s pressure lubrication providing the required oil flow. This design also improves longevity by allowing longer crankshaft service intervals, which means less labor and money spent on two wheels.


The KTM 450 SX-gearbox F’s is designed for lightweight performance without sacrificing durability. The gear ratios did not need to be changed since they were perfectly suited to the vast displacement engine’s power output. Still, the secondary drive (sprockets) balance was shorter (13/49) for better responsiveness. All four-stroke engines are equipped with a gear sensor, which allows for changing engine characteristics based on engine load for each gear. The sophisticated “no-dirt” gear lever design prevents dirt from accumulating and, in combination with the dependable gearbox, ensures that the next gear is always a simple click away.

The DDS clutch (damped diaphragm steel) on the KTM 450 SX-F is highly robust, with a wear-free steel basket and new heat-resistant clutch plates designed by KTM. It employs a diaphragm instead of coil springs, resulting in far easier clutch operation. The new diaphragm spring is also small enough to integrate a dampening mechanism into the clutch hub, enhancing traction and durability. The BREMBO hydraulic system also allows for simple and accurate clutch modulation.



The frame of the KTM 450 SX-F is expertly built from hydroformed chromium-molybdenum steel tubes that are robot welded to guarantee the highest standards of consistent quality, much like the rest of the KTM SX series. The frame’s rigidity is carefully calibrated to enable responsive handling and works in tandem with the suspension to produce great agility and high-speed stability. All 2020 KTM SX model frames have legal protection and an extremely durable powder coating. The lightweight aluminum subframe offers the rider a pleasant sensation and allows for smooth mobility over the seat.


The one-piece swingarm of the KTM 450 SX-F is made utilizing a gravity die-cast manufacturing method for excellent strength and lightweight. It features a broad range of rear-wheel adjustment, permitting a smaller wheelbase on tighter, twistier tracks or a higher wheelbase on longer, more choppy courses for better stability. An all-new chain measurement lines on the swingarm are visible above, making adjustments more accessible and accurate.


On an all-new 2022 450 SX-F KTM Powerful Dirt Bike, KTM employs lightweight, CNC-machined hubs and high-end Excel rims to give optimum stability and nominal weight. The new aluminum spoke nipples are designed in such a way that they reduce the need to tighten the spokes regularly. The latest Dunlop Geomax-MX33 tires are fixed on the wheels, offering more fantastic grip and stability while competently transmitting all the power to the ground.

Front suspension

The super-lightweight WP XACT front forks with AER technology are standard on all full-size 2022 450 SX-F KTM Powerful Dirt Bike with revised settings. It’s a 48mm USD air-sprung fork with damping functions on the right side and an air spring on the left. A two-chamber system with the capsuled air cartridge is used on the left leg to decrease air pressure loss. In simple terms, it implies that even if the exterior seal leaks, the internal cartridge pressure retains the motorcycle in a normal position. An all-new air spring is elementary and can easily adjust to any rider’s weight with a solo air valve and the included air pump. The new right fork leg features a damping cartridge that may alter the track conditions and the rider’s preferences to match single damping leg needs. Additionally, the fork top caps contain a novel design that enables easier compression and rebound adjustment.

Rear suspension

The new WP XACT monoshock is standard on the 2022 450 SX-F KTM Powerful Dirt Bike, and it was designed primarily to function in tandem with the whole frame and swingarm architecture; the new linkage system and the WP XACT fork. It contains high-quality machined and anodized components that lend a touch of sophistication and make it appealing beyond merely being practical. It’s completely adjustable, including high and low-speed compression, so you can fine-tune it to fit any track and rider’s tastes.


The new 2022 450 SX-F KTM Powerful Dirt Bike has high-tech Brembo S.P. Brakes as standard equipment. The acclaimed system, when combined with the lightweight wave discs, gives the best degree of braking efficiency, allowing you to out-brake the competitors.

A Gas tank

The lightweight polyethylene fuel tanks are standard on the new 2022 450 SX-F KTM Powerful Dirt Bike. The gasoline tank’s form offers sleek ergonomics while preserving a 1.85-gallon fuel capacity. The new inner thread of the filler cap guarantees secure and stable sealing.

Ergonomics and Comfort


Even while digging deep ruts, sophisticated ‘no-dirt’ footpegs avoid clogging the footpeg pivot. If someone wants to ride at a higher position, just install the 2019 EXC footpegs that are 6mm taller than the SX models.


The seat on an all-new 2022 450 SX-F KTM Powerful Dirt Bike is designed to complement the range’s dynamic performance-oriented ergonomics. The silicone stripes on the seat cover offer the rider a better feel and grip. The seat is held to the motorcycle with a solo long, lateral screw, making it safe and straightforward.


The high-strength aluminum tapered handlebar delivered by NEKEN is standard on all full-size 2022 450 SX-F KTM. The handlebar is fixed using rubber-dampened mountings that can easily be adjusted to two different settings. On the right side, there’s an all-new ODI vulcanized grip, and on the left, there’s a comfortable ODI lock-on grip that doesn’t require any wire or adhesive.
