Yamaha XTZ 660 Ténéré [1994-1995]: The Refined Desert Wanderer

Introduction

The Yamaha XTZ 660 Ténéré represents a fascinating chapter in the evolution of adventure motorcycles. Produced between 1994 and 1995, this fifth-generation model straddles the line between Yamaha’s rugged off-road heritage and the demands of riders seeking a more road-friendly endurance machine. While it lacks the minimalist desert-racing DNA of the original 1983 Ténéré, this iteration shines as a versatile, no-nonsense workhorse capable of blending asphalt reliability with light off-road mischief.

After spending a week with a meticulously maintained 1994 example, it’s clear this bike was engineered for riders who value mechanical simplicity without sacrificing modern comforts. Let’s dissect what makes this single-cylinder legend tick.

Design & Ergonomics: Form Meets Functionality

Aesthetic Evolution

The 1994 redesign introduced a streamlined fairing with dual round headlights, a styling nod to its bigger sibling, the XTZ 750 Super Ténéré. This update gave the bike a distinctly modern (for its era) face, while the 20-liter fuel tank retained the classic Ténéré silhouette. The bodywork isn’t just for show—it deflects wind effectively at highway speeds, though taller riders might still feel some buffeting.

Riding Position

With a 34.1-inch (865 mm) seat height, the XTZ demands confidence at stops, but the narrow seat profile lets most riders dab a foot comfortably. The upright handlebars and slightly rear-set pegs create a natural posture for long hauls. Yamaha’s focus on ergonomics shines here: even after a 300-km (186-mile) day, fatigue is minimal.

Weight Distribution

At 195 kg (429 lbs) wet, the Ténéré isn’t a featherweight, but its mass is centralized low in the frame. This pays dividends when navigating rocky trails or urban traffic. The 58.9-inch (1,495 mm) wheelbase enhances stability at speed, though it does require deliberate input when flicking through tight corners.

Performance: The 5-Valve Heartbeat

Engine Character

The liquid-cooled 660cc single-cylinder engine is a masterpiece of 90s engineering. With 5 valves (3 intake, 2 exhaust) and a SOHC layout, it delivers 48 HP (35 kW) at 6,250 RPM and 56.9 Nm (42 ft-lb) of torque at 5,250 RPM. Cold starts are drama-free thanks to the electric starter, and the engine settles into a smooth idle at 1,300 RPM.

On the road, power builds linearly from 3,000 RPM, with a satisfying surge past 4,500 RPM. The 5-speed gearbox ratios are well-spaced, though the gap between 4th and 5th feels pronounced. Cruising at 110 km/h (68 mph) in top gear sees the engine loping along at 5,000 RPM—relaxed enough for all-day touring.

Off-Road Manners

While not a hardcore enduro, the Ténéré handles gravel and dirt roads with poise. The 21-inch front wheel rolls over ruts confidently, and the 220 mm front / 200 mm rear suspension travel absorbs smaller impacts gracefully. However, the weight becomes apparent in deep sand or technical terrain—this is a bike best suited to adventure touring, not Dakar-style rallies.

Braking & Handling

The single 282 mm front disc with a 4-piston caliper provides strong stopping power, though it lacks the modulation of modern ABS systems. On loose surfaces, the rear 245 mm disc locks easily, demanding finesse. Pavement handling is surprisingly agile for a tall bike, aided by the 43 mm telescopic forks and adjustable rear Monocross shock.

Competition: How It Stacked Up

Honda XR650L

The air-cooled XR650L was lighter (144 kg / 317 lbs dry) and more off-road-focused but lacked the Ténéré’s road manners. With only 43 HP, it felt anemic on highways, and the absence of liquid cooling made it prone to overheating in slow traffic.

Suzuki DR650S

Suzuki’s contender shared the Ténéré’s dual-sport intent but used a simpler air-cooled engine. While the DR650S was cheaper and easier to maintain, its 43 HP output and basic suspension couldn’t match the Yamaha’s refined performance.

KTM 640 Adventure

The Austrian rival was lighter and packed a punchier engine (50 HP), but its reliability and vibey single-cylinder made it a niche choice. The Ténéré’s smoother power delivery and lower maintenance needs appealed to touring-focused riders.

Verdict: The XTZ 660 Ténéré carved a niche as the most road-capable middleweight adventure bike of its era, sacrificing some off-road prowess for touring comfort.

Maintenance: Keeping the Legend Alive

Key Service Points

1. Valve Adjustments:
2. Intake: 0.10–0.15 mm (0.004–0.006 in)

3. Exhaust: 0.15–0.20 mm (0.006–0.008 in)
   Check every 6,000 km (3,728 miles). Stellite valves are durable but prone to tightening.

4. Oil Changes:

5. Use SAE 20W-40 (2.7 L with filter). The dry-sump system requires checking oil level with the engine warm and idling.

6. Carburetor Tuning:

7. The Teikei Y26PV carb benefits from periodic cleaning. Set the air screw to 2.5 turns out as a baseline.

8. Cooling System:

9. Replace coolant every 2 years (1.2 L capacity). Monitor for weepage at the water pump—a common failure point.

10. Chain & Sprockets:

11. The 15/45 sprocket combo wears evenly. Upgrade to an O-ring chain (110 links) for longer service life.
