Honda CR250R [1981-1987]: A Timeless Two-Stroke Legend

Introduction

The Honda CR250R isn’t just a dirt bike—it’s a revolution on wheels. For riders who lived through the 1980s, this machine represents the golden age of two-stroke motocross dominance. Even today, the 1981–1987 CR250R generation is revered as a benchmark for raw power, agility, and engineering simplicity. Whether you’re a vintage MX enthusiast or a modern rider curious about the roots of off-road performance, the CR250R demands respect. After a day spent thrashing one through muddy trails and sandy whoops, it’s clear why this bike became a legend. Let’s dive into what makes this generation so special.

Engine Performance: The Heart of a Beast

At the core of the CR250R lies its 249cc liquid-cooled two-stroke engine, pumping out 58–60 PS (43–44 kW)—equivalent to 57–59 horsepower. By modern standards, these numbers might seem modest, but the delivery is anything but. The engine’s powerband hits like a sledgehammer, with a ferocious mid-range surge that demands respect. There’s no gentle ramp-up here: crack the throttle open, and the front wheel instantly floats skyward.

The carburetion (tuned with a 1.5–2-turn air screw) is remarkably crisp for its era, though it rewards patience. Let the engine warm up to its 1,200 ± 100 RPM idle, and it’ll purr like a chainsaw on a leash. The NGK BR9EG or BR9EIX spark plugs (gapped at 0.6 mm) ensure reliable ignition, but this engine isn’t for the faint-hearted. It thrives on aggression, rewarding riders who embrace its explosive character.

Fuel efficiency? Forget it. With a 7.5-liter (2.0-gallon) tank, you’ll be refilling often if you’re riding hard. But that’s part of the charm—this bike exists to be ridden flat-out.

Chassis and Handling: Lightweight Precision

Weighing just 97 kg (214 lbs), the CR250R feels like a feather compared to today’s four-strokes. The 33mm telescopic fork (holding 190ml of SAE 10W oil) and Honda’s iconic Pro-Link rear suspension (introduced in 1981) deliver a plush yet controlled ride. Over rocky terrain, the chassis remains composed, and the 15/41 sprocket combo paired with a 102-link chain provides snappy acceleration without sacrificing top-end pull.

Tire pressure matters. Honda recommended 2.0 BAR (29 psi) front and rear—a setting that balances grip and slide predictability. On loose dirt, the CR250R carves turns with a level of feedback that modern bikes often mute with electronic aids. This is raw, unfiltered riding: every bump, rut, and weight shift telegraphs through the handlebars.

Design and Ergonomics: Function Over Frills

The CR250R’s design is pure 1980s motocross: slim, angular, and unapologetically utilitarian. The seat is narrow but surprisingly comfortable for a race bike, and the peg-to-bar relationship encourages an aggressive riding stance. Maintenance access is straightforward—no fairings to remove, just a bare-bones layout focused on durability.

The 7.5-liter tank sits low, keeping the center of gravity neutral. Even during high-speed runs, the bike feels planted. Rustic? Yes. Effective? Absolutely.

Competition: How the CR250R Stacks Up

In the 1980s, the CR250R faced fierce rivals:
- Yamaha YZ250: Known for a broader powerband but heavier chassis.
- Suzuki RM250: Sharper cornering but less reliable suspension.
- Kawasaki KX250: Brutal low-end torque but rougher ergonomics.

The Honda stood out with its Pro-Link rear suspension, which offered better bump absorption than Yamaha’s mono-shock or Suzuki’s rising-rate linkage. While the RM250 was nicknamed "Rocket Ship" for its cornering, the CR250R dominated in technical sections where stability mattered. Kawasaki’s KX250 appealed to brute-force riders, but Honda’s balance of power and precision made it the choice for tacticians.

Maintenance: Keeping the Legend Alive

Owning a vintage CR250R isn’t just about riding—it’s about stewardship. Here’s how to keep yours thriving:

Key Tips:

1. Two-Stroke Oil: Use high-quality premix. The engine burns oil, so skip cheap brands.
2. Spark Plugs: Swap the NGK BR9EG/BR9EIX plugs every 10–15 hours.
3. Chain Care: The 102-link chain stretches quickly. Upgrade to a modern O-ring chain (available at MOTOPARTS.store) for longevity.
4. Suspension Fluid: Replace fork oil annually. Stiction from old oil ruins the plush feel.
5. Brakes: DOT 4 fluid absorbs moisture—bleed the system yearly.

MOTOPARTS.store Recommendations:

• Performance Sprockets: Try a 14-tooth front sprocket for tighter trails.
• Air Filters: Swap foam filters frequently in dusty conditions.
• Grips: Upgrade to modern rubber for better vibration damping.
