Kawasaki BN 125 Eliminator (1998-2007): A Timeless Entry-Level Cruiser

Introduction

The Kawasaki BN 125 Eliminator, produced from 1998 to 2007, remains a standout in the 125cc cruiser segment. Designed for urban agility and beginner-friendly ergonomics, this motorcycle blends minimalist cruiser styling with approachable performance. While it’s no speed demon, its lightweight chassis, low seat height, and reliable air-cooled engine make it a favorite for new riders and city commuters. Let’s dive into what makes this generation of the Eliminator a enduring choice for those seeking a no-fuss, stylish ride.

Design & Ergonomics

Kawasaki nailed the cruiser aesthetic with the BN 125 Eliminator. Its stretched fuel tank (13 liters / 3.4 US gallons), chrome-plated wire-spoke wheels, and stepped two-up seat give it a laid-back personality that belies its small displacement. The 680 mm (26.8-inch) seat height is forgiving for shorter riders, while the forward-set footpegs and upright handlebars create a relaxed posture perfect for short commutes or weekend rides.

Color options evolved over its production years, ranging from understated black and silver to vibrant reds and blues. Later models, like the 2005 Galaxy Silver edition, added subtle flair with metallic finishes. The tank-mounted turn signals and compact instrumentation keep the design clean, though the analog speedometer and basic warning lights feel dated by modern standards.

Engine & Performance

At the heart of the Eliminator lies a 124cc air-cooled single-cylinder engine producing 12 HP (8.8 kW) at 9,500 RPM and 9.6–10 Nm (7.1–7.4 lb-ft) of torque. These numbers won’t set records, but the engine’s focus on low-to-mid-range grunt makes it surprisingly peppy in city traffic. The Mikuni BS28 carburetor delivers crisp throttle response, and the 5-speed transmission shifts smoothly once you adapt to its slightly notchy feel.

Top speed hovers around 100–102 km/h (62–63 mph), though sustained highway riding feels strained. Where this engine shines is fuel efficiency: expect 3.4 liters per 100 km (69 mpg), making it a budget-friendly choice. The gear-driven balancer reduces vibrations, and the CDI ignition system ensures reliable starts—even in colder weather.

Handling & Ride Experience

Weighing 128–135 kg (282–298 lbs) dry, the Eliminator feels nimble at low speeds. The 33mm telescopic fork and twin rear shocks (with 5-way preload adjustment) handle city potholes competently, though rough roads can jostle the rider. Steering is light thanks to the narrow 90/90-17 front tire, while the 130/90-15 rear tire adds stability.

Braking is adequate for its weight: the 260mm front disc (single-piston caliper) provides predictable stopping power, but the rear drum brake lacks bite during sudden stops. The 1,470 mm (57.9-inch) wheelbase and 34° rake angle strike a balance between maneuverability and straight-line stability.

Competition

The Eliminator 125’s closest rivals include:

1. Honda Shadow 125: Shares similar cruiser styling but uses a smoother SOHC engine. The Shadow’s suspension is plusher, but it’s heavier at 140 kg (309 lbs).
2. Yamaha Virago 125: Boasts a V-twin-like aesthetic and slightly better highway composure. However, its maintenance costs are higher due to a more complex valve setup.
3. Suzuki GN125: A standard-style alternative with superior parts availability globally. Less “cool factor” but arguably more practical for daily use.

The Eliminator’s edge lies in its simplicity and Kawasaki’s reputation for bulletproof reliability. While competitors might offer marginally better specs, few match its charm as a starter cruiser.

Maintenance & Ownership

The BN 125 Eliminator is notoriously low-maintenance, but here are key points to keep it running smoothly:

• Oil Changes: Use SAE 10W-40 oil (1.1L without filter, 1.2L with). Replace every 3,000–4,000 km (1,800–2,500 miles).
• Valve Adjustments: Check every 6,000 km (3,700 miles). Intake valves: 0.08–0.12 mm (0.003–0.005 in), exhaust: 0.15–0.19 mm (0.006–0.007 in).
• Chain Care: The 132-link chain requires regular lubrication. Upgrade to an O-ring chain for longer intervals.
• Tire Pressure: 1.5 bar (22 psi) front / 1.75 bar (25 psi) rear. Stick to the stock 90/90-17 and 130/90-15 sizes for optimal handling.
• Carb Tuning: The Mikuni BS28 carburetor benefits from occasional cleaning, especially if the bike sits unused.

MOTOPARTS.store Recommendations:
- High-flow air filters for improved throttle response.
- Aftermarket exhaust systems to shed weight and enhance the engine’s character.
- Gel seat pads for long-term comfort during city rides.
