Suzuki GN 250 (1983-1999): The Timeless Entry-Level Cruiser That Refuses to Quit
Introduction
The Suzuki GN 250 is the motorcycle equivalent of a trusty pair of boots – unpretentious, reliable, and always ready for adventure. Produced from 1983 to 1999, this air-cooled single-cylinder workhorse became a global phenomenon, serving as a first bike for generations of riders, a commuter staple in crowded cities, and even an off-road companion in developing nations. While its specs sheet might seem humble by modern standards, the GN 250’s true magic lies in its simplicity and durability – qualities that make it a compelling used-bike purchase even today. After spending a week with a well-maintained 1995 model, here’s why this Suzuki remains relevant decades after its debut.
Design & Ergonomics: Classic Styling Meets Everyday Practicality
The GN 250’s design is a masterclass in minimalist cruiser aesthetics. Its teardrop fuel tank (holding 10.3 liters / 2.7 US gal), pulled-back handlebars, and bench-style seat create a laid-back riding posture. At 740 mm (29.1 inches), the seat height is accessible even for shorter riders, while the 129-140 kg (284-308 lbs) weight feels manageable at stops.
Chrome accents on the exhaust, fenders, and mirrors add subtle flair without veering into gaudiness. The analog speedometer and odometer cluster are refreshingly straightforward – no digital distractions here. Pillion passengers get a basic grabrail, though the flat seat offers decent comfort for short trips.
Where the GN 250 truly shines is in its utilitarian details:
- Tire Sizes: 3.00-18 front and 4.60-16 rear (or 120/90-16 in later models) strike a balance between stability and maneuverability
- Lighting: A classic circular headlight provides adequate illumination for city riding
- Mod Potential: The simple frame and abundant aftermarket parts make customization easy
Engine Performance: Modest Power, Maximum Charm
At the heart of the GN 250 lies a SOHC 4-valve single-cylinder engine displacing 249 cc (15.2 cu in). Output figures vary slightly across model years:
- Peak Power: 17-22 HP (12.4-16.4 kW) @ 7,800-8,500 RPM
- Torque: 16-19.6 Nm (11.8-14.5 lb-ft) @ 4,000-6,500 RPM
The air-cooled mill pairs with a 5-speed transmission and chain final drive. Thumb the electric starter (a welcome upgrade from kick-only systems), and the engine settles into a throaty idle that’s surprisingly characterful for a 250cc single.
On the Road Impressions:
- 0-60 km/h (0-37 mph): Adequate for city traffic, reaching ~5 seconds
- Top Speed: 122 km/h (76 mph) indicated – enough for highway stints, though vibrations become noticeable above 100 km/h (62 mph)
- Fuel Efficiency: 30-35 km/l (70-82 mpg) makes it staggeringly cheap to run
The Mikuni 34mm carburetor delivers crisp throttle response, though cold starts sometimes require patience. Keep the tach needle between 3,000-7,000 RPM, and the GN 250 feels lively enough for urban combat. The 5-speed gearbox shifts with positive clicks, though finding neutral can be finicky when hot.
Handling & Braking: Predictable and Forgiving
Suzuki’s chassis engineers nailed the GN 250’s geometry for novice-friendly handling:
- Wheelbase: 1,349 mm (53.1 inches)
- Front Suspension: 34mm telescopic forks with 216ml SAE 10W oil
- Rear Suspension: Dual shocks with 5-way preload adjustment
At low speeds, the bike flicks through traffic with bicycle-like ease. The narrow 18-inch front wheel (3.00-18 tire) provides quick steering, while the 16-inch rear (4.60-16 or 120/90-16) adds stability. Cornering clearance is limited by the footpegs, but that’s par for the cruiser course.
Braking performance reflects the era:
- Front: Single 276mm disc (adequate with period-correct rubber)
- Rear: Drum brake (requires firm lever pressure)
ABS is absent, of course, but the lightweight chassis forgives most panic stops. For modern safety, consider upgrading to sintered brake pads and fresh DOT 4 fluid.
Competition: How the GN 250 Stacks Up
In the 250cc cruiser segment, the Suzuki faced three key rivals:
- Honda Rebel 250
- Liquid-cooled parallel-twin smoother but more complex
- Lower seat height (683mm vs 740mm)
-
Less aftermarket support today
-
Yamaha Virago 250
- V-twin character with better highway manners
- Heavier at 148 kg (326 lbs)
-
Prone to starter motor issues
-
Kawasaki Eliminator 250
- Sportier styling
- Similar power but less low-end torque
- Rare parts availability in 2023
The GN 250’s Edge:
- Air cooling eliminates radiator maintenance
- Chain drive allows easy gearing changes (stock 15/41 sprockets)
- Global parts availability via MOTOPARTS.store
