ENGINE & EXHAUST

Engine:

The KTM 250 SX powerplant is a 2-stroke burning marvel, with a counter-balance shaft for low engine vibration, as well as a reliable hydraulically operated DDS clutch. It has a twin-valve controlled power valve, which contributes massively to making the KTM 250 SX engine the most competitive 2-stroke in its class.

Cylinder Head:

One could argue that this is where the magic happens. The KTM 250 SX’s cylindar has a bore of 66.4 mm and is fitted with a Twin-Valve powervalve system. The exhaust port is machined for precise power valve function, providing excellent overall power delivery. By using the two supplied springs, the power characteristics can be changed quickly and easily, ensuring optimal settings for different tracks and rider preference.

Crankshaft:

The crankshaft delivers a 72 mm stroke that produces optimal torque and revs, firing the KTM 250 SX forward at a rapid pace. It is also perfectly balanced with minimal vibration. The crankshaft is situated in the perfect position to centralize mass, contributing to better agility and handling.

Crankcases and Engine Covers:

The KTM 250 SX boasts compact, lightweight engine cases which are manufactured using a high-pressure die-cast production process. This helps in reducing weight while retaining strength and durability. The design also allows for optimal shaft arrangements close to the center of gravity, resulting in better mass centralization and rideability. Most importantly, however, the engine covers feature a smart surface structure that reduces the wear caused by the rider’s boots, keeping them looking as fresh as the day the bike rolled off the production line.

Transmission:

There’s no greater thrill than taking a big 2-stroke through the gears. Thanks to a strong 5-speed gearbox built to suit any kind of motocross track, the KTM 250 SX is happy to oblige all day long, with gear ratios specifically developed to match the power delivery of the 250 cc engine. The gearbox also features a “no-dirt” gear shifter. Similar to the footpeg design, it prevents the build-up of dirt and ensures the next gear is always available, no matter what the conditions.

Balancer Shaft:

The KTM 250 SX engine design allows for the addition of a lateral balancer shaft, which helps keep engine vibrations to a minimum. This means you can keep charging harder for longer without bad vibes putting you off your game.

Clutch:

The KTM 250 SX featues a diaphragm steel clutch, which quite literally, puts the control back in your hand. It features a durable, one-piece clutch basket and primary gear, made of high-strength billet steel, guaranteeing unbeatable reliability. It is fitted with extremely heat-resistant steel carrier friction discs, which are pre-tensioned by means of a diaphragm spring, ensuring the most effective disengagement of the clutch. This design substantially reduces the operating force required to pull the clutch and is made even easier with the BREMBO hydraulic system.

Carburetor:

Getting the fuel to the cylinder comes courtesy of a MIKUNI TMX carburetor. The settings on the 38 mm flat slide carburetor perfectly suit the airbox and exhaust design, providing smooth, controllable power all the way through the rev range.

Ignition:

All KTM 2-stroke motocross models feature a CDI control unit with advanced hardware that improves the starting behavior of the engine. This means they fire perfectly everytime, all the time.

Cooling:

Keeping things cool when the going gets heated, is a set of radiators ideally positioned for a lower center of gravity. By using computational fluid dynamics technology together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions.

Exhaust:

Their’s more to it than ‘braaaap!’. The exhaust plays a key role in packing that signature 2-stroke punch. When it comes to power delivery and performance, the exhaust is developed specifically for the KTM 250 SX and plays a key role packing a punch. In addition, its special shape provides slimmer ergonomics while still operating safely within the noise limits for racing.

Frame:

The KTM 250 SX makes use of a pin-point accurate hydro-formed chromium-molybdenum frame. These are robot welded to ensure the highest levels of consistent quality, stiffness, and responsive handling. And when paired with the WP PRO COMPONENT suspension, provides excellent agility and high-speed stability. For 2022, all KTM SX frames are powder-coated in full-factory orange and come with standard frame protectors. The subframe is made from lightweight aluminum and provides a great feeling for the rider, as well as easy movement across the seat.

Swingarm:

The KTM SX range features a one-piece, gravity die-cast swingarm. This manufacturing process ensures exceptional strength at the lowest possible weight, and offers a wide range of adjustment for the rear wheel, allowing for a shorter wheelbase on tighter, twisty tracks, or a longer wheelbase for greater stability on longer straightaways. Additionally, the swingarm’s chain measurement markings are visible from above, meaning adjustments are easily made.

Wheels:

The full-size KTM SX machines make use of lightweight, CNC-machined hubs and high-end Excel rims, wrapped in the latest Dunlop Geomax-MX33 tires. The aluminum spoke nipples feature a design that conveniently reduces the frequency with which the spokes need to be tightened.

Front Suspension:

The KTM 250 SX makes use of lightweight 48 mm USD WP XACT front forks with AER technology. These air-sprung forks feature separate functions in each fork leg, with damping functions on the right side and the air spring on the left. The left leg features a two-chamber system with a capsuled air cartridge, preventing loss of air pressure. Essentially, this means that in the rare case of a leaking outer seal, the internal cartridge pressure maintains its standard position. The air spring is also easy to use and can be adjusted to any rider weight via a single air valve and an air pump which is supplied. The right fork leg integrates a damping cartridge to fit single damping leg requirements and can be adjusted to track conditions or rider preferences. Additionally, the fork top caps feature easy adjustment, with compression done from the top, and rebound from the bottom.

Rear Suspension:

All KTM SX models make use of a WP XACT mono-shock, which has been developed to work with the entire frame and swingarm architecture, as well as the linkage system. This setup perfectly compliments the WP XACT fork, to provide balance and handling performance. It features high-quality machined and anodized components, is fully adjustable, including high and low-speed compression, and allows you to set the shock up precisely to suit any track and rider’s preferences.

Triple Clamp:

High-quality, CNC-machined triple clamps have become a KTM trademark. With a precisely calculated stiffness and 22 mm offset, these have been developed to match the flex characteristics of the frame and fork, resulting in unbeatable handling and stability. An hour meter is fitted as standard on the upper triple clamp on all SX models, keeping the rider informed of the number of hours spent tearing up the track and when the next service is due.

Brakes:

The KTM SX range relies on the best in the business when it comes to slowing down. High-tech Brembo brakes take charge of the front and rear, ensuring maximum rider feel, less brake fade, and high-quality build quality. Combined with lightweight wavey discs, this race-proven system provides the highest level of braking efficiency, providing unrivaled stopping power.

Fuel Tank:

Feeding the high-revving machine beneath, a lightweight, 7-liter polyethylene fuel tank ensures an uninterrupted flow of fuel at all times. The shape of the fuel tank also aids in the overall, slim ergonomics of the bike, without compromising on fuel capacity.

Airbox:

The airbox on the KTM 250 SX ensures optimal flow dynamics, and together with its intake snorkels, leads to maximum power and quick throttle response. Despite the obvious performance advantages, the design also offers maximum protection against soiling of the air filter. The large Twin-Air air filter is mounted on a cleverly designed stiff cage that minimizes incorrect installation. As found on previous models, filter maintenance is quick and easy and does not require tools – a standard, original feature from KTM.
