2017 KTM 450 SX-F Factory Edition Base

2017 KTM 450 SX-F Factory Edition

We build Factory Editions. Championship winning bikes, like this one. Thanks to its compact SOHC (single overhead camshaft) engine delivering explosive but controllable power, it is the weapon of choice for our Factory Teams around the world. Experts will notice its revolutionary WP AER 48 forks, the anodized triple clamps and sprocket, its upgraded Akrapovic muffler, the orange frame or the D.I.D DirtStar rims. The rest will only see a blur blasting past. Is it Ryan Dungey? Possibly. Or it could be you.

• ENGINE

With new features such as more compact dimensions, stronger performance throughout the rev range and a weight reduction of 1,8 kg, this newly developed powerplant is the lightest 450 engine on the off-road market. With a reworked single overhead camshaft cylinder head and the latest electronic fuel injection, the 450 SX-F has unrivalled power of more than 62 hp and a highly efficient power delivery.

• ELECTRIC STARTER

Like all KTM 4-Stroke motorcycles, the 450 SX-F is started with ease by pushing a button. Demonstrated time and time again, an electric starter can become an invaluable advantage in the heat of competition.

• CLUTCH

The 450 SX-F employs the KTM-developed DDS clutch (Damped Diaphragm Steel) with a wear-free steel basket and extremely heat resistant clutch plates. This design is distinguished by employing a diaphragm spring instead of coil springs, which makes for a considerably easier clutch action. The diaphragm spring also leaves sufficient space for a damping system integrated into the clutch hub, which benefits for both traction and durability.

• ENGINE MANAGEMENT SYSTEM

The completely reworked Keihin Engine Management System, with electronic fuel injection, features an all-new 44 mm throttle body, which provides instantaneous response and maximum performance thanks to a revolutionary injector position. The new ECU (Engine Control Unit) includes a launch control for more efficient starts with different maps according to the gear sensor selection. In addition, the rider can activate optional maps for a different power delivery via the map select switch on the handlebar.

• TRANSMISSION

The new engine of the 450 SX-F uses a lightweight 5-speed gearbox which perfectly matches to the power delivery of the large displacement engine. In addition the 1st and 3rd gears are treated with a special surface treatment for better reliability.

• WHEELS

CNC machined hubs and high-end D.I.D. DirtStar ?wheels rims are fitted with Dunlop GEOMAX MX32 tires as standard. These latest MX tires from Dunlop have been developed by KTM factory racing in the USA, with full factory testing and expert rider feedback in racing. They guarantee flawless traction and outstanding performance.

• BRAKES

High-tech Brembo brakes have always been standard equipment on KTM offroad bikes, and are combined with newly designed and weight-reduced Wave discs made by GALFER featuring also an improved heat resistance. The ultimate solution in braking technology. Weight reduction front 63 g, rear 32 g.
