Product details

The 2027 KTM 350 SX-F is a 349.7 cc 4-stroke motocross bike, positioned between the 250 and 450 in the KTM lineup: more torque than a 250, less inertia than a 450. For 2027, it receives a revised steel frame and comes standard with a Quickshifter, launch control, and traction control. It weighs 102.4 kg without fuel. It is a competition machine, reserved for tracks and private land.

350 Engine: The torque of a big bore, the agility of a 250

The 349.7 cc 4-stroke single-cylinder engine is fueled by Keihin EFI with a 44 mm throttle body. KTM announces an engine weight of 27.5 kg. This is the advantage of the 350 displacement: usable power across the entire rev range, without the inertia of a heavy block to manage in every direction change. The engine is tilted 2° rearward to centralize masses, improving handling and reducing rear squat under acceleration. According to KTM, the silencer improves throttle response while slightly reducing noise.

Revised 25CrMo4 steel frame for 2027

KTM stays true to steel: the 25CrMo4 double-cradle central frame is hydroformed, laser-cut, and robot-welded. Its longitudinal and torsional flex is calculated so the frame absorbs impacts and reduces rider fatigue over laps. For 2027, the rear shock mounting area has been optimized, engine mounts have been revised, and front wall thickness has been adjusted with input from KTM Factory Racing. The subframe combines reinforced polyamide and aluminum.

WP XACT AER 48 mm inverted fork of the KTM 350 SX-F

WP XACT AER 48 mm fork: rider weight-adapted adjustment

The 48 mm WP XACT AER inverted fork offers 310 mm of travel. Its air spring replaces the steel spring: preload is adjusted using an air pump, supplied standard by KTM, allowing the fork to be adapted to the rider's weight without disassembling anything. Compression and rebound are adjusted by hand via clickers at the top and bottom of the fork. The CNC-machined triple clamp and forged steering stem ensure precise tube alignment for a smooth-sliding fork.

WP XACT shock absorber: 300 mm of travel, tool-free adjustment

At the rear, the linkage-mounted WP XACT shock offers 300 mm of travel, with settings derived from KTM Factory Racing teams according to the manufacturer. Compression is adjustable by hand, separately for high and low speeds: low speed affects ride height and traction, high speed handles heavy impacts like landing jumps. The geometry clears the linkage to reduce bottoming out, and thinner linkage bolts save weight.

Brembo hydraulic clutch control of the KTM 350 SX-F

Brembo hydraulic clutch and standard Quickshifter

The wet multi-disc DS clutch is operated by a Brembo hydraulic system: the bite point remains consistent even when the clutch heats up at the end of a moto, where a cable setup would tend to vary. The transmission features 5 speeds, with a 24:72 primary drive and a 520 chain. The Quickshifter allows upshifting from 2nd to 5th gear without touching the clutch, with the throttle wide open.

2 maps and handlebar traction control

The handlebar map switch offers two engine maps. Map 1 delivers power in a more linear fashion, suited for slippery surfaces or riders looking for consistency. Map 2 is punchier, for high-traction tracks. The same switch activates traction control, which limits rear wheel spin on wet or muddy surfaces: on a track watered in the morning, it allows you to get on the gas earlier coming out of corners without the rear end stepping out.

Launch control: nailing the holeshot

Launch control is activated by simultaneously pressing the traction control and Quickshifter buttons. It limits the power sent to the rear wheel during launch, reducing wheelspin and the risk of looping out when the starting gate drops. Combined with the Quickshifter for clutchless upshifts, its goal is simple: reach the first turn in a strong position without relying entirely on clutch modulation under pressure.

Ergonomics: knee grip and standing position

The dual-component plastic radiator shrouds channel air directly to the radiators. The handlebar-seat-footpeg triangle is designed to provide excellent knee grip surfaces, especially when standing. Seat height is 958 mm with a ground clearance of 343 mm: this is a full-sized adult motocross bike. The die-cast footpegs are designed to catch less in deep ruts.

Tool-free access to the Twin Air filter on the KTM 350 SX-F

Maintenance: tool-free air filter access

The Twin Air filter is accessible without tools by removing the left side panel, featuring a mounting system that prevents incorrect installation. Suspension adjustments can also be done by hand, speeding up trackside work. The chain guide and protector have been revised to snag less and accumulate less mud around the swingarm, and the wiring harness routing has been modified to reduce wear. The fuel tank holds approximately 7.2 liters.

Braking and Dunlop Geomax MX34 tires

The bike is equipped with a front disc brake and a rear disc brake. The rear brake pedal has been stiffened for improved braking feel. It comes stock with Dunlop Geomax MX34 tires, a stiff-casing motocross tire that KTM states maintains performance up to 30% longer than the previous generation. The knob pattern helps clear mud to maintain traction on loamy terrain.

7. What is the suspension travel?

310 mm at the front and 300 mm at the rear.

8. What is the seat height?

958 mm, with a ground clearance of 343 mm. Make sure the rider is comfortable touching the ground before purchasing.
