Motorcycle specifications KTM250 SX 2014 Bastion du baston

the 250 SX is the motocross bike with the best power-to-weight ratio. Its lightweight two-stroke engine achieves unrivalled performance in an extremely lightweight chassis - serious competition for four-strokes.

wHEELS

Lightweight CNC-machined hubs, top-of-the-range Excel rims and black-coated spokes with lightweight aluminum nipples ensure minimum weight and maximum stability. Pirelli Scorpion MX Mid Soft 32 tires offer perfect grip and excellent performance.

bRAKES

High-tech Brembo brakes have long been standard on KTM off-road bikes, with lightweight Wave disc brakes for optimum braking performance. For the 2014 model year, we note a new brake cocotte with a new compensation reservoir, a smaller piston diameter, and a new lever with optimized kinematics. Thanks to this and the optimized brake pads, front brake performance and dosability have been further significantly improved.

bODYWORK

The aim was to create a more ergonomic and functional fairing, so that every detail of the bike is in perfect harmony with the rider. The plastic mouldings of the front mudguard are a model of solidity thanks to their sophisticated structure and fastening.

sADDLE

The perfectly ergonomic saddle of the 2014 model year features an improved foam core for greater comfort and sturdiness.

aIR BOX

The airbox design ensures optimum protection of the air filter from dirt, and maximum air flow for enhanced performance. Changing the Twin Air filter in just a few seconds and without tools has long been standard at KTM.

fUEL TANK

All SX models are equipped with a new 7.5-liter fuel tank made of lightweight polyethylene.the inner thread of the lid and the lid itself have been modified, making it easier and more reliable to close. Four-stroke motocross bikes feature the same fuel pump system as four-stroke enduro models, allowing the optional installation of larger tanks available in the PowerParts catalog or on enduro models.

gUIDON

All SX models are equipped with super-strong Renthal Fatbar 827 tapered handlebars, shaped to meet motocross requirements. The tried-and-tested KTM system allows the handlebars to be fixed in a choice of four positions. For 2014, a large black/silver Renthal Crash Pad provides additional impact protection for the rider.

gRAPHICS

A refined new graphic design with clear lines underlines the uncompromising demands of this modern off-road bike.

fRAME

The modern frame design of SX models in lightweight, high-strength chromium-molybdenum steel tubing combines maximum longitudinal rigidity with optimum torsional rigidity. This not only ensures good handling and precise steering, but also excellent riding stability.

sUSPENDING ARM

The cast aluminum swingarm has been designed using state-of-the-art calculation and simulation software; the design and wall thickness ensure minimum weight for optimum strength and a perfectly defined flex. For the 2014 model year, engineers have improved the chain guide and its attachment points on the swingarm for greater reliability and reduced weight.

sUSPENSION / DAMPING

Both the rear shock absorber and the 48 mm inverted fork from WP Suspension guarantee optimum damping behavior and responsiveness. For the 2014 model year, the telescopic fork boasts optimized adjustment and greater reserves against shock loads. Fork rebound and compression can be quickly adjusted to the needs of the rider and the track. The rear shock absorber also offers High-Speed and Low-Speed compression damping.

fORK TIPS

High-quality CNC-milled fork tees have been standard equipment at KTM for years. They ensure precise handling and clearly emphasize the bending characteristics and therefore the responsiveness of the telescopic fork.

eNGINE

The engine of the 2014 model year has been upgraded with a new Boyesen-Performance valve gear to offer improved responsiveness. The carburetor setting and ignition curve have also been adapted.

eMBRAYAGE

The new KTM 250 SX engine features a damped DDS (Damped Diaphragm Steel) clutch with a wear-resistant steel bell housing, allowing the use of thinner steel plates for minimum integration width. Elastic washers for preloading reduce operating forces and leave space for integrated hub damping. The result: more traction and a gearbox with less stress. And with Brembo's optimized hydraulic clutch, the rider has everything under control right from the start.

cULASSE

The 2014 250 SX features a new cylinder head with optimized combustion chamber. The advantage is that this leads to more efficient combustion for better responsiveness and higher torque across the entire load and rpm range. A new CDI-Box has been integrated with an optimized ignition curve to achieve more efficient combustion for better power delivery and optimal handling.
