2014 Ktm 250 Sx Dirt Bike on 2040-motos

KTM Other description

The 250 SX is considered to be the motocross bike with the best power-to-weight ratio. The lightweight 2-stroke engine scores with unrivaled performance, wrapped into an extremely lightweight chassis - a serious competitor for the more complex 4-stroke contenders.Highlights¿¿¿Engine: In 2014, the 250 SX engine has been improved with a redesigned reed valve housing featuring Boyesen high-performance reeds for better responsiveness. A revised carburetor setting and ignition curve also allow for increased performance.¿¿¿Cylinder Head: The 250 SX has a new cylinder head with optimized combustion chamber. The benefit is more efficient combustion for better response and increased torque over the entire load and engine speed range. A new CDI box with optimized ignition mapping has been fitted for more effective combustion for better power delivery and optimum rideability.¿¿¿Air Box: The airbox design offers maximum protection of the air filter against soiling while ensuring maximum airflow for top performance. The Twin Air filter can be changed without tools in seconds, a standard for KTM.¿¿¿Fuel Tank: All models of the SX range have a new, lightweight polythene tank with a capacity of 1.98 gallons. The new filler cap with the inside thread makes for an easier and reliable closure.¿¿¿Clutch: A new DDS clutch (Damped Diaphragm Steel) with a wear-free steel cage is fitted to the new KTM 250 SX engine, allowing use of thin steel discs for minimum overall width. 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.¿¿¿Triple Clamps: Top-quality, CNC-machined triple clamps have been something of a KTM trademark. Ensuring a precise handling, they perceptibly support the flex characteristics, and with it, the fork's action.¿¿¿Swingarm: Designed using the latest in calculation and simulation software, the design and wall thickness of the cast aluminum swingarm have been optimized for minimum weight at optimum stiffness and precisely defined flexibility provides perfect stability at minimum weight. For 2014, the engineers have revised the chain guide to increase reliability while lowering the weight.¿¿¿Suspension/Damping: The rear monoshock as well as the 48mm upside-down front fork by WP Suspension guarantee the best response and damping characteristics. In 2014, the fork has more reserves against bottoming out thanks to their optimized setting.
