2015 KTM SX 450 F

2015 KTM 450 SX-F

With the 450 SX-F, KTM has a winning motorcycle in its range, which derives its potential from a high-capacity engine and a chassis perfectly tuned to the power unit. The 450 SX-F is the no. 1 choice for the Red Bull/ KTM Factory Team in the AMA Championship. No wonder; the compact SOHC engine guarantees brutal yet controllable power with its revolutionary injection technology. Above all, the 450 SX-F scores highly compared with other large 4-strokes in terms of performance and handling. Ideal for every motocrosser who sees plenty of torque, ample on-tap power and a controllable ride as their complete package.

• Bodywork

KTM engineers have focussed on designing the bodywork ergonomically and functionally in such a way that the whole motorcycle is in perfect harmony with the rider down to the very last detail. The front fender is a perfect example of how molded plastic components can gain maximum stability with a well thought out structure and well-conceived attachment.

• Graphics

A new, refined graphic design with clear lines underlines the high demands made of a modern, state-of-the-art offroad motorcycle.

• Seat

The ergonomically perfectly designed seat is equipped with a durable foam core, ensuring both generous comfort and high stability.

• Airbox

At the same time, the design of the airbox guarantees optimum protection of the air filter from dirt plus maximum air throughput for the highest performance. Quick replacement of the twin-air filter - without tools and in a matter of seconds - has long since been an unrivalled KTM standard.

• Fuel Tank

All models in the SX range are equipped with a 7.5 litre, lightweight polyethylene fuel tank. The fuel pump system used on the 4-stroke motocross models is the same as that used on the 4-stroke enduro models, thereby allowing optional fitting of larger tanks from the PowerParts range or from the enduro models.

• Handlebar

All SX models are equipped with the extremely sturdy, tapered Renthal Fatbar 827 handlebar that features an offset specially designed to meet the demands of motocross. In accordance with the proven KTM standard, the handlebar can be fixed in a choice of four positions. For MY 2015, it is equipped with softer two-component grips to spare the rider's hands.

• Frame

The modern frame design of the SX models, comprising lightweight, high strength, chrome-molybdenum steel section tubes, combines maximum longitudinal stiffness with optimum torsional stiffness. A forged and milled cross-tube connects the two frame halves with the connecting rod of the linkage on the new SX frame for 2015. Omission of the weld seams leads to very precise manufacturing tolerances and greater safety - moreover, it saves another 60 grams of weight.

• Linkage / Shock Absorber

The revamped damping system for MY 2015 features a new linkage with optimized geometry. The flatter progression with a higher initial rate ensures greater stability and lowers the rear end. In addition, the new design saves another 40 grams of weight. The fully adjustable WP 5018 shock absorber has been completely retuned to suit the new linkage.

• Engine

The compact 60hp powerhouse, featuring an overhead camshaft and state-of-the-art electronic fuel injection system, excels with unrivalled performance and highly efficient power development. Newly developed oil strainer sealing rings are used for MY 2015 to provide better durability in the most extreme conditions and a longer service life.
