Yamaha XJ 600 N [1994–1997] Review: The Approachable Inline-Four That Defined an Era
Introduction
The Yamaha XJ 600 N stands as a testament to 1990s motorcycle engineering – a harmonious blend of practicality, reliability, and just enough sporty character to keep things interesting. Designed during an era when naked bikes began dominating urban landscapes, this air-cooled inline-four carved its niche as a versatile companion for both daily commutes and weekend adventures. Let’s dissect why this machine remains a beloved choice for riders seeking an unfiltered, analog motorcycling experience.
Design & First Impressions
At first glance, the XJ 600 N exudes understated confidence. Its double-cradle steel frame supports a compact, muscular silhouette, with the 38mm telescopic forks and monoshock rear suspension hinting at balanced dynamics. The 770mm (30.3-inch) seat height feels welcoming for riders of varying statures, while the 193 kg (425 lb) dry weight – manageable even at parking speeds – masks its heft once in motion.
The minimalist bodywork showcases Yamaha’s focus on function over frivolity. The round headlight, analog gauges, and exposed engine components give it a timeless, "honest motorcycle" aesthetic. Practical touches like the 17L (4.4-gallon) fuel tank and upright riding position prioritize real-world usability, though the lack of wind protection becomes apparent above 100 km/h (62 mph).
Engine & Performance
The Heart of the Matter
The 599cc DOHC inline-four engine is where the XJ 600 N truly shines. Generating 61 HP (45 kW) at 8,500 RPM and 53–65 Nm (39–48 lb-ft) of torque depending on model year, this air-cooled mill delivers linear power delivery that’s forgiving for newcomers yet engaging for seasoned riders.
Cold starts require patience – the 28mm Mikuni carburetors demand proper choke technique – but once warmed to its 1,200 RPM idle, the engine settles into a smooth, turbine-like hum. Throttle response remains crisp through the midrange, with a noticeable surge around 6,000 RPM as the exhaust note transitions from bassy growl to metallic wail.
The 6-speed gearbox shifts with mechanical precision, though finding neutral at standstill can be finicky. Chain final drive maintenance is straightforward, and the 16/48 sprocket combination strikes a balance between acceleration and highway cruising. At 120 km/h (75 mph), the engine hums along comfortably at ~5,500 RPM in sixth gear, though vibrations through the bars and pegs intensify past 140 km/h (87 mph).
Handling & Ride Dynamics
Yamaha nailed the chassis geometry here. The 25° rake and 97mm (3.8-inch) trail provide stable yet responsive steering, while the 1,445mm (56.8-inch) wheelbase inspires confidence during high-speed sweepers. The non-adjustable 38mm forks and preload-adjustable monoshock handle city potholes admirably, though aggressive cornering reveals their limitations – the front end dives noticeably under hard braking, and the 140mm/110mm (5.5"/4.3") suspension travel struggles with sharp mid-corner bumps.
Braking performance aligns with era expectations. The single 320mm front disc with twin-piston caliper requires a firm squeeze for urgent stops, while the 245mm rear disc offers progressive feel. Modern radial tires (110/80-17 front, 130/70-18 rear) dramatically improve grip over period-specific rubber.
Comfort & Practicality
The XJ 600 N’s true strength lies in its everyday usability. The bench-style seat provides ample room for rider movement, though its foam density leads to numb butt syndrome after 90 minutes. The neutral riding triangle – low pegs, wide bars, and neutral spine angle – works brilliantly for urban crawls, with vibration dampening sufficient for 2-hour highway stints.
Storage options are limited to aftermarket solutions, but the 17L fuel tank delivers ~300 km (186-mile) range at a claimed 18.1 km/L (42.6 mpg). The lack of a fuel gauge (only a reserve switch) requires old-school trip meter discipline.
Competition
In the mid-90s middleweight naked arena, the XJ 600 N faced formidable rivals:
- Honda CB600F Hornet: More modern liquid-cooled engine (1998+), sharper handling, but heavier and less accessible for DIY maintenance.
- Suzuki GSX600F Katana: Sportier ergonomics and fairing, but cramped for taller riders and pricier to insure.
- Kawasaki Zephyr 550: Retro charm and bulletproof reliability, though down on power and lacking the XJ’s sixth gear.
Where the Yamaha excelled was in its mechanical simplicity. The air-cooled engine avoided radiator complexities, while the tubular steel frame made crash repairs economical. For riders valuing approachable performance over cutting-edge specs, the XJ 600 N often came out on top.
