KTM 450 SX-F 2022 for Sale at Moorooka KTM in Moorooka, QLD | Specifications and Review Information
UNRIVALLED LEGACY
The 2022 KTM 450 SX-F makes its presence felt - even before it sets out of pit lane. Thanks to a powerful, championship-winning engine churning out an industry-leading 63hp, the KTM 450 SX-F delivers holeshot-winning performance with confident, bullet-proof handling lap after lap. In simple terms, the KTM 450 SX-F remains the one to beat when the gate drops, and is the closest you'll get to a factory race machine, right out of the box.
Exhaust
When it comes to power delivery and performance, the exhausts on all KTM 4-stroke SX-F models play a key role in getting to the head of the pack. Featuring a model-specific header pipe with an advanced Flow Design Header, the design allows the exhaust to be disassembled without removing the shock absorber. The aluminum sleeve, end cap, and internal design of the silencer allow for slimmer ergonomics, making the bike feel slimmer without any compromise to regulatory noise limits.
Engine
The KTM 450 SX-F engine sits at the pinnacle of the 4-stroke motocross range, delivering a compact, single overhead camshaft design with the latest electronic injection system, resulting in unbeatable power. Its success lies in its ability to deliver usable power throughout the rev range while combining class-leading electronics, and adjustability - not to mention being the lightest 450 cc motocross engine on the market.
Cooling
Keeping things cool when the going gets heated, is a set of radiators ideally positioned for a lower center of gravity. By using computational fluid dynamics technology together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions.
TRANSMISSION
Part of the KTM 450 SX-F's acceleration comes courtesy of years of refining gear rations to ensure the best performance possible from the large displacement engine. The transmission is also engineered to be ultra-lightweight but has the durability to perform race after race. A 13/49 secondary drive also allows for instant response out of the corners, while the 4-stoke specific gear sensor provides the option of different engine characteristics for each gear, depending on engine load.
ENGINE MANAGEMENT SYSTEM
The state-of-the-art KEIHIN Engine Management System, with electronic fuel injection, features a 44 mm throttle body. The injector position guarantees optimal atomization of the fuel and air on the way to the combustion chamber, resulting in instant response and maximum performance when opening the throttle.
CLUTCH
The KTM 450 SX-F is fitted with the extremely durable, KTM-developed DDS clutch, with a wear-free steel basket and heat-resistant clutch plates. It makes use of a diaphragm spring instead of the usual coil springs, which results in considerably easier clutch action. The diaphragm spring is also compact enough to allow for a damping system to be integrated into the clutch hub, contributing to better traction and durability. What that means is, it can take everything you - or the Supercross Series - can throw at it.
FRAME
The KTM 450 SX-F makes use of a pin-point accurate hydro-formed chromium-molybdenum frame. These are robot welded to ensure the highest levels of consistent quality, stiffness, and responsive handling. And when paired with the WP PRO COMPONENT suspension, provides excellent agility and high-speed stability. For 2022, all KTM SX frames are powder-coated in full-factory orange and come with standard frame protectors. The subframe is made from lightweight aluminum and provides a great feeling for the rider, as well as easy movement across the seat.
WHEELS
The full-size KTM SX machines make use of lightweight, CNC-machined hubs and high-end Excel rims, wrapped in the latest Dunlop Geomax-MX33 tires. The aluminum spoke nipples feature a design that conveniently reduces the frequency with which the spokes need to be tightened.
BRAKES
The KTM SX range relies on the best in the business when it comes to slowing down. High-tech Brembo brakes take charge of the front and rear, ensuring maximum rider feel, less brake fade, and high-quality build quality. Combined with lightweight wavey discs, this race-proven system provides the highest level of braking efficiency, providing unrivaled stopping power.
AIRBOX
The airbox on the KTM 450 SX-F ensures optimal flow dynamics, and together with its intake snorkels, leads to maximum power and quick throttle response. Despite the obvious performance advantages, the design also offers maximum protection against soiling of the air filter. The large Twin-Air air filter is mounted on a cleverly designed stiff cage that minimizes incorrect installation. As found on previous models, filter maintenance is quick and easy and does not require tools - a standard, original feature from KTM. Every SX-F comes with an additional PowerParts airbox cover featuring additional air intake holes for higher engine performance, meaning that the airbox can be customized for different engine characteristics or to suit track conditions.
