KTM 250 SX-F [2022] Review: A Motocross Weapon Refined

Introduction

The 2022 KTM 250 SX-F arrives as a precision tool for motocross warriors – a bike that doesn’t just participate in the 250cc four-stroke class but dominates it through relentless innovation. Designed for riders who demand razor-sharp responsiveness and race-ready performance straight out of the crate, this Austrian machine blends cutting-edge engineering with the raw, unapologetic aggression that defines KTM’s SX lineage. Having spent time throwing dirt with this bike on technical tracks and fast straights, it’s clear: this isn’t just a motorcycle; it’s a statement.

Engine Performance: Controlled Fury

At the heart of the 250 SX-F lies a 249.9cc liquid-cooled single-cylinder engine that’s been massaged to near perfection. The 78mm bore and 52.3mm stroke configuration prioritizes explosive top-end power without sacrificing the low-end grunt needed to claw out of corners. What stands out immediately is the Keihin engine management system – throttle response is crisp, almost telepathic, with zero lag between wrist input and rear wheel action.

The electric starter (a blessing after stalling mid-race) fires up the engine with a throaty bark that transitions into a smooth idle. On the track, the powerband feels broad for a 250cc machine. It pulls hard from 6,000 RPM, surging forward with a linear delivery that builds to a frantic 14,000 RPM crescendo. The 5-speed gearbox slots cleanly under load, though the ratios feel tightly spaced – ideal for keeping the engine in its sweet spot during sprints between jumps.

Compared to earlier models, the Brembo hydraulic clutch offers a lighter lever pull, reducing arm pump during marathon motos. Fanatics of two-strokes might miss the hit of a power valve, but the SX-F compensates with tractable power that’s easier to harness in rutted corners or loose soil.

Handling: Dance With the Dirt

KTM’s chromoly steel frame has become legendary for balancing flex and rigidity, and the 2022 iteration takes this further. At 99 kg (218 lbs) dry, the bike feels shockingly light when flicked sideways. The 1495mm wheelbase and 26.5° rake strike a near-perfect compromise between straight-line stability and cornering agility.

The WP XACT suspension package elevates the experience. Up front, the 48mm forks swallow braking bumps and landing impacts with a plushness that borders on psychic – you’ll charge into whoops sections faster just because the bike lets you. Out back, the linkage-mounted monoshock provides 300mm of travel, staying composed even when the track gets brutal. Setup is key here; lighter riders might find the stock settings too firm for slower trails, but on a prepped MX circuit, it’s magic.

Standing at 950mm (37.4"), the seat height is typical for the class, but the narrow chassis design makes it feel accessible. Combine this with 370mm (14.6") of ground clearance, and you’ve got a bike that’s as happy railing berms as it is clearing logs on an endurocross course.

Brakes and Wheels: Stop on a Dime

Brembo’s signature touch is all over the braking system. The single 220mm front disc bites hard without being grabby, offering the kind of modulation that lets you trail-brake deep into corners. Out back, the rear brake has a progressive feel – crucial for controlling slides on off-camber turns.

Wire-spoked wheels (21" front, 19" rear) wrapped in Dunlop MX33 tires (80/100-21 front, 110/90-19 rear) provide predictable grip across conditions. The 1.0 BAR (14.5 PSI) tire pressure recommendation works well for most tracks, though serious racers might tweak this based on soil hardness.

Competition: How It Stacks Up

The 250cc motocross arena is fiercely contested. Here’s how the KTM holds its ground:

• Yamaha YZ250F: Yamaha’s engine emphasizes mid-range torque, making it slightly friendlier for beginners. However, the KTM counters with a lighter chassis (YZ250F weighs 106 kg dry) and more adjustable suspension.
• Honda CRF250R: Honda’s reliability is unmatched, but the CRF feels heavier in rhythm sections. The SX-F’s Brembo clutch and hydraulic actuation give it a technical edge.
• Kawasaki KX250: Kawasaki’s Showa suspension is plush, but the KTM’s WP XACT setup handles big hits better. The KX250 also lacks the SX-F’s electric starter – a glaring omission in 2022.

Where the KTM shines is its race-ready ethos. While rivals often require aftermarket tweaks to reach full potential, this bike delivers championship-level performance from day one.

Maintenance: Keeping the Orange Beast Alive

Owning a high-strung four-stroke demands discipline. Here’s how to keep your 250 SX-F in fighting shape:

1. Oil Changes: Run premium synthetic oil (10W-50 recommended) and replace every 10-15 hours. The magnetic drain plug often reveals metal shavings – don’t panic unless they’re chunk-sized.
2. Air Filter Care: Clean the twin-air filter after every ride. Use biodegradable cleaner and lightly oil – over-oiling can suffocate the engine.
3. Cooling System: The 7.0L coolant capacity (50% water, 50% ethylene glycol) works well, but upgrade to a high-pressure radiator cap if you’re battling slow, technical terrain.
4. Chain Maintenance: The 520 chain needs regular tension checks (55-60mm slack). A worn chain accelerates wear on the $400+ sprockets.
5. Brake Fluid: Flush DOT 4/5.1 fluid annually. Spongy levers? Time for a bleed.

MOTOPARTS.store Pro Tips:
- Swap stock brake pads for sintered metal versions in muddy conditions.
- Install a skid plate if you’re venturing beyond MX tracks.
- Our CNC-machined clutch covers reduce overheating during long motos.

Conclusion: The Apex Predator

The 2022 KTM 250 SX-F isn’t here to coddle casual riders. It’s a machine built for those who view motocross not as a hobby, but a vocation. From the way the engine screams toward rev limiter to the confidence-inspiring suspension, every component feels engineered to shave tenths off lap times. Yes, it demands respect – neglect maintenance, and it’ll bite – but pour in the care (and premium parts from MOTOPARTS.store), and this bike will repay you with podiums. In the hyper-competitive world of 250cc motocross, the SX-F remains the benchmark others chase… for now.
