Kawasaki KX 250 [1999-2002]: A Nostalgic Powerhouse That Still Demands Respect

Introduction

The early 2000s marked the final glory days of two-stroke dominance in motocross, and the Kawasaki KX 250 [1999-2002] stands as a fiery testament to that era. While modern four-strokes have since taken over the scene, this green machine remains a cult classic among riders who crave raw, unfiltered adrenaline. With its screaming 249cc engine, aggressive ergonomics, and race-bred suspension, the KX 250 wasn’t just a bike—it was a statement. Let’s throw a leg over this legendary motocrosser and explore why it still turns heads (and wrenches) decades later.

Design & First Impressions

The moment you approach the KX 250, its purpose is clear: this is a no-nonsense race bike. The 1999-2002 generation retained Kawasaki’s iconic lime green livery but introduced sharper bodywork that gave it a more aggressive stance compared to its late-’90s predecessors. The 85.6-inch (2,174 mm) overall length and 58.3-inch (1,481 mm) wheelbase create a balanced profile that looks ready to leap off the starting gate.

The cockpit is pure motocross minimalism. The narrow, 37.4-inch (950 mm) seat height feels taller than some competitors, but it rewards taller riders with room to maneuver. Every surface—from the flat, grippy seat to the angular fuel tank—is designed to keep you locked in during hard acceleration or mid-air adjustments.

Engine Performance: Two-Stroke Fury

The heart of the KX 250 is its 249cc liquid-cooled two-stroke engine, and oh, what a heart it has. Kawasaki’s engineers tuned this mill to deliver 55.6 HP (40.6 kW) with a powerband that hits like a sledgehammer. There’s no gentle buildup here—crack the throttle open, and the front wheel instantly goes light, accompanied by that signature two-stroke shriek that echoes across the track.

Riding this bike is a masterclass in momentum management. The 5-speed transmission is crisp, but you’ll rarely need more than third gear on most tracks. The real magic happens between 7,000 and 8,500 RPM, where the KX 250 pulls harder than a teenager’s first love. Unlike modern four-strokes, there’s no engine braking to save you—just pure, unadulterated acceleration that demands respect (and a strong clutch hand).

Handling & Suspension: Born for the Chop

With a dry weight of 213.8 lbs (97 kg), the KX 250 feels astonishingly light when the track gets ugly. The chassis strikes a perfect balance between rigidity and flex, absorbing square-edged hits while remaining precise in rutted corners.

Front suspension duties are handled by 46mm Kayaba inverted forks, adjustable for compression and rebound. Out back, the Uni-Trak linkage system and a fully adjustable shock keep the 110/90-19 rear tire planted. On hard-packed terrain, the setup feels slightly stiff, but it comes alive in sand or deep loam, where the bike floats over obstacles like a hovercraft.

Where the KX 250 truly shines is in its flickability. Slamming through rhythm sections or carving tight berms feels intuitive, thanks to the centralized mass and 21-inch front wheel. It’s not as razor-sharp as Suzuki’s RM250, but it trades a hint of agility for stability at speed—a fair compromise for most riders.

Braking & Control

Braking is handled by a single 250mm front disc and a 240mm rear disc, both gripped by Nissin calipers. The front brake lacks the initial bite of modern setups but offers progressive feel that’s ideal for scrubbing speed before corners. The rear, however, requires a delicate touch—stomp on it mid-corner, and the lightweight frame will pivot faster than a politician’s promise.

The Renthal handlebar (original equipment) provides a comfortable bend for most riders, though aggressive racers might swap it for a taller or narrower aftermarket option. Clutch pull is surprisingly light for a two-stroke, making it manageable during long motos—provided you’ve upgraded the stock springs.

Competition: How It Stacks Up

The late-’90s/early-2000s 250cc two-stroke class was a golden era of rivalry. Here’s how the KX 250 fared against its fiercest competitors:

1. Yamaha YZ250:
   The YZ250 was the KX’s arch-nemesis, boasting a broader powerband and superior suspension. However, the KX countered with harder-hitting midrange pull and a more durable clutch. For riders who preferred aggression over finesse, the Kawasaki often won out.

2. Honda CR250R:
   Honda’s flagship two-stroke had a reputation for razor-sharp handling and innovative engine designs (e.g., the 2001 case-reed motor). But the CR’s finicky power delivery couldn’t match the KX’s visceral hit, especially on starts and steep climbs.

3. Suzuki RM250:
   The RM250 was the lightweight champ, with a flickable chassis that dominated tight tracks. However, its narrow powerband made it less forgiving than the KX, particularly for less experienced riders.

Verdict: The KX 250 carved its niche as the “brute” of the class—less refined than the YZ, less technical than the CR, but unmatched in raw, seat-of-the-pants excitement.

Maintenance: Keeping the Green Beast Alive

Owning a 20-year-old motocross weapon isn’t for the faint of heart, but the KX 250’s simplicity makes it a DIY dream. Here’s what to watch:

Top-End Rebuilds

Two-strokes live hard, and the KX 250 is no exception. Piston replacements are needed every 15-20 hours of hard riding. MOTOPARTS.store recommends: - Wiseco Pro-Lite Pistons: Forged durability and tighter tolerances than stock.
- Cometic Gasket Kits: Perfect seal for consistent compression.

Air Filter Care

The stock foam filter works well but needs frequent cleaning. Upgrade to a Twin Air Filter with a No-Toil Pre-Oiled Kit for quicker maintenance between motos.

Suspension Refresh

Old fork seals? Replace them with SKF Seals and pair with Maxima Racing Suspension Fluid for buttery-smooth action. Don’t forget linkage bearings—Pivot Works Kits prevent slop in the Uni-Trak system.

Brake Upgrades

Modern EBC Brake Pads (Sintered or Organic) improve stopping power without altering the stock rotors. Pair with Galfer Braided Steel Lines for firmer lever feel.

Tire Recommendations

Stick with the classic Dunlop Geomax MX33 combo (80/100-21 front, 110/90-19 rear) for all-around grip. For sand, Michelin Starcross 5 Soft Terrain tires hook up like velcro.
