2021 KTM 250 SX-F

2021 KTM 250 SX-F

The KTM 250 SX-F was primed for global domination and is set to continue its dominance for 2021. Not only is it the lightest bike in its class, but it also offers an unrivalled, confidence-inspiring power delivery, making it a great choice for both amateur and professional riders. Laying the power down effectively is the secret to fast lap times and this capable package has all the right credentials to get the most important job done - getting to the chequered flag first.

ENGINE & EXHAUST

• ENGINE

Renowned as the strongest engine in 250 competition, the 2020 version maintains its dominance. Its compact structure contributes to excellent mass centralization, which supports the easy rideability of the bike. The 2020 model features a new, stronger oil pump intermediate gear that, along with several other small, but important refinements, contributes to improved reliability. The low weight of only 57.1 lbs, in combination with the compact engine layout and unrivalled power, once again makes the KTM 250 SX-F a real force to be reckoned with, yet still easy to ride for both amateur and professional riders.

• CYLINDER HEAD

An integral part of the class-leading power delivery is the cutting-edge DOHC (double overhead camshaft) cylinder head. It features two overhead camshafts which activate the titanium valves (intake 32.5 mm, exhaust 26.5 mm) via the super-light, DLC coated finger followers. The camshafts have a friction-optimized super-fine surface and a timing that delivers incredibly refined power.

CHASSIS

• FRAME

The frame on the KTM 250 SX-F has to cater for the dynamic riding styles typical of the class it fits into. As with the entire SX range, the frame is professionally crafted from hydroformed chromium molybdenum steel tubes that are robot welded to ensure the highest levels of consistent quality. The carefully calculated stiffness of the frame delivers responsive handling and works perfectly with the suspension to provide excellent agility and high-speed stability. All 2020 KTM SX frames feature a highly durable powder coating and come with standard frame protectors. The subframe is made from lightweight aluminum and provides great feeling for the rider, as well as easy movement across the seat.

• SWINGARM

The KTM 250 SX-F's one-piece swingarm is manufactured using a gravity die-cast production process, for exceptional strength at the lowest possible weight. It 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, more choppy tracks. The swingarm's chain measurement markings are visible from above, making adjustment simpler and more accurate.

ERGONOMICS & COMFORT

• SEAT

All KTM SX models feature a seat that perfectly matches the range's dynamic performance-oriented ergonomics. The seat cover features silicone strips that provide better feel and grip for the rider. The seat is conveniently fixed to the bike using one long, lateral screw, making it secure and easy to handle.
