Yamaha YZ250 (2022) Review: The Two-Stroke Motocross Legend Evolves

Introduction

The Yamaha YZ250 needs no introduction in the dirt bike world. For 2022, this iconic two-stroke motocross machine returns with subtle refinements that sharpen its competitive edge while staying true to its roots as a lightweight, high-revving adrenaline machine. As one of the last remaining carbureted two-strokes in production, it occupies a unique space in modern motocross - a bridge between old-school simplicity and contemporary chassis technology. After putting it through its paces on MX tracks and technical trails, here's why this blue beast remains relevant in the age of fuel injection and four-stroke dominance.

Engine Performance: Pure Two-Stroke Theatre

At the heart beats a 249cc liquid-cooled two-stroke engine that's remained fundamentally unchanged for years - not because Yamaha stopped innovating, but because they nailed the formula early. The 66.4mm bore x 72mm stroke configuration delivers explosive mid-range punch that sends roost flying with every throttle blip, while the Keihin PWK38S carburetor provides crisp response that fuel-injected rivals still struggle to match.

The powerband tells a beautiful story:
- Low-End: Surprisingly tractable for a 250cc two-stroke, pulling cleanly from 3,500 RPM
- Mid-Range: Hits like a sledgehammer between 6,000-8,000 RPM
- Top-End: Screams to a 9,200 RPM limiter with that classic two-stroke banshee wail

Riders will appreciate the 5-speed transmission's perfect spacing - second and third gear handle most MX track work, while fifth becomes your desert overdrive. The hydraulic clutch (a rarity in two-strokes) offers buttery modulation even when fanning through corners.

Key Maintenance Tip: That 10.6:1 compression ratio demands strict adherence to Yamaha's premix specs (32:1 ratio recommended). MOTOPARTS.store carries NGK BR8EG/BR8EIX spark plugs for optimal combustion.

Chassis & Handling: Precision Meets Brutality

Yamaha's aluminum semi-double cradle frame strikes a Goldilocks balance between stiffness and flex. At 103kg (227 lbs) wet, it flicks sideways with BMX-like agility yet remains planted at speed. The 2022 updates make meaningful differences:

• Narrower Tank/Flatter Seat: 38mm slimmer through the knees vs previous models
• KYB SSS Suspension: 48mm inverted forks with 300mm travel (11.8")
• Braking Upgrades: 270mm front rotor with 30% more pad contact area

Through consecutive whoops, the Speed-Sensitive System forks demonstrate why they're considered class-leading - initial stroke softness absorbs small chatter while progressively resisting bottoming on big hits. Out back, the KYB shock's 315mm (12.4") travel handles everything from hard landings to seated acceleration bumps.

The Dunlop Geomax MX33 tires deserve special mention. Their block-within-a-block tread pattern claws through loamy turns while resisting chunking on hardpack. Run them at Yamaha's recommended 1.0 Bar (14.5 PSI) for ideal deformation characteristics.

Rider Ergonomics: Control Through Comfort

Yamaha's 2022 ergo updates transform the riding experience:

• Flatter Seat: Enables easier weight shifts front/rear
• Reduced Knee Angle: 27.7° rake combines with 1,481mm (58.3") wheelbase for stable yet agile steering
• Lower Pegs: 361mm (14.2") ground clearance remains intact while improving cornering leverage

At 970mm (38.2"), the seat height remains tall - shorter riders may want to consider a suspension lowering link from MOTOPARTS.store's catalog. Standing riders benefit from revised handlebar bend that reduces arm pump on long motos.

Competition: How It Stacks Up

KTM 250 SX

• Advantages: 3kg lighter, electric start, TPU airbox
• YZ250 Counters: More linear power delivery, superior suspension action
• Part Swap Tip: Many YZ riders install KTM-style hour meters for easier maintenance tracking

Husqvarna TC 250

• Advantages: Hydroformed frame, Magura clutch
• YZ250 Counters: More durable wheel bearings, easier carb access
• Upgrade Path: Husky's composite subframe could inspire weight-saving mods

Kawasaki KX250

• Advantages: Air-cooled simplicity, lower seat height
• YZ250 Counters: 15% more peak power, modern chassis geometry

The YZ250's true ace? Aftermarket support. From Boyesen RAD valves to GYTR exhausts, there's more performance-adders available than for any European rival.

Maintenance: Keeping the Beast Alive

Critical Service Intervals

1. Piston Rings: Every 30-40 hours (sooner for aggressive riders)
2. Reed Valves: Inspect every 50 hours for fraying
3. Suspension Fluids: 100-hour refresh recommended
4. Brake Pads: 2022's larger pistons extend life to ~80 hours

MOTOPARTS.store Pro Tips

• Carb Tuning: Swap stock jets for JD Jetting kits when altitude/temp changes exceed 500m/15°C
• Chain Upgrades: Replace OEM 520 chain with DID ERT3 for 2x lifespan
• Cooling Mods: Boyesen Supercooler kit reduces temps by 12°C
• Air Filter Hacks: Twin Air Bio-Oil filters last 3x longer between cleanings

Conclusion: The Last True Two-Stroke?

The 2022 Yamaha YZ250 isn't just a dirt bike - it's a statement. In an era where four-strokes dominate dealership floors, this blue warrior keeps the two-stroke faith alive with updates that matter. From its revised ergonomics to the brutally effective engine, every component feels purpose-built for riders who value mechanical simplicity and visceral feedback over electronic nannies.

Will it win straight-up drag races against 450Fs? No. But few machines deliver this combination of lightweight fury and chassis sophistication. For motocross purists and woods warriors alike, the YZ250 remains a benchmark - a bike that rewards skill while punishing complacency. Keep the premix fresh, the suspension dialed, and this Yamaha will outlast trends, technologies, and probably your own courage.
