2015 KTM 250 SX Base

2015 KTM 250 SX

The 250 SX is regarded as the motocross motorcycle with the best power-to-weight ratio. The lightweight 2-stroke engine scores highly with unrivalled performance packed in an extremely light chassis – a formidable rival for the costlier 4-stroke competitors.

• 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 moulded plastic components can gain maximum stability with a well thought out structure and well-conceived attachment.

• Seat

The ergonomically perfectly designed seat is equipped with a durable foam core, ensuring both greater comfort and higher 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 liter, lightweight polyethylene fuel tank.

• 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.

• Wheels

The wheels fitted for MY 2015 feature black coated, high-end Excel rims with lightweight, CNC-machined hubs and spokes with lightweight aluminium nipples, allowing highest levels of stability to be achieved, while keeping weight to a minimum. New Dunlop Geomax MX 52 tires were developed in collaboration with the KTM USA factory team and offer perfect traction with top performance. The new rear sprockets save 50 grams in unsprung mass.

• Brakes

High-tech brakes from Brembo have always been standard equipment on KTM offroad bikes and, together with the lightweight Galfer Wave brake discs, they are the measure of all things in terms of brake technology. As the best brakes in the motocross class, they remain unchanged for MY 2015.

• Engine

The powerful KTM 250 SX engine unites an unbeatable power-to-weight ratio with outstanding performance and extremely easy handling.

• Clutch

A new DDS clutch (Damped Diaphragm Steel) with diaphragm spring and wear-free steel cage is fitted to the KTM 250 SX engine. The diaphragm spring, which preloads the package, not only reduces the operating force required to pull the clutch, but also provides space for integrated hub damping. The result: more traction and protection for the transmission. And with updated hydraulic clutch actuation from Brembo, the rider has everything under control right from the start.

• 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.
