Yamaha XTZ 660 Ténéré [1991–1993]: The Desert Falcon That Conquered Pavement

Introduction

The Yamaha XTZ 660 Ténéré, produced between 1991 and 1993, represents a fascinating pivot in the evolution of dual-sport motorcycles. Born from Yamaha’s Paris-Dakar racing legacy, this generation of the Ténéré traded some of its desert-roaming DNA for practicality, making it a versatile companion for riders who craved adventure without sacrificing road manners. With its liquid-cooled 5-valve engine, slimmed-down chassis, and a design that whispers "go anywhere," the XTZ 660 remains a cult classic for riders who value mechanical simplicity and rugged charm. Let’s take this retro icon for a spin and see how it holds up today.

Design & Ergonomics: A Tall Order with Purpose

At first glance, the XTZ 660 Ténéré towers over its peers with a seat height of 865 mm (34.1 inches). While this might intimidate shorter riders, the narrow profile of the fuel tank—a deliberate design choice to reduce “leg spread”—makes mounting manageable. The stepped seat flows seamlessly into the 20-liter (5.3-gallon) tank, creating a rider triangle that’s surprisingly comfortable for long hauls.

The cockpit features a Paris-Dakar-inspired fairing with a basic but effective analog dash. Wind protection is modest by modern standards, but tucking behind the screen at highway speeds reduces fatigue. The aluminum rear rack and passenger grab rail are utilitarian touches, perfect for strapping down gear or yanking the bike out of mud.

Yamaha’s decision to integrate the oil reservoir into the frame not only slimmed the chassis but also lowered the center of gravity, making the 195 kg (429 lbs) wet weight feel manageable once moving. The overall aesthetic is functional rather than flashy—a no-nonsense tool ready for work.

Engine & Performance: The 5-Valve Thumper

The heart of the XTZ 660 is its 659 cc single-cylinder engine, notable for being the first production single with a 5-valve head. This engineering marvel delivers 48 HP at 6,250 RPM and 56.9 Nm (42 ft.lbs) of torque at 5,250 RPM. On startup, the engine settles into a relaxed idle at 1,300 RPM, with minimal vibration thanks to a balancer shaft and rubber-mounted handlebars.

On the Road:
- The powerband is forgiving, pulling cleanly from 3,000 RPM in top gear. Short-shifting through the 5-speed gearbox is the key to smooth progress, though a clutch dab wakes things up if you bog down.
- Top speed hovers around 167 km/h (104 mph), but the real joy lies in its midrange punch—ideal for overtaking or climbing hills with a loaded rack.
- Fuel economy averages 16.7 km/l (40 mpg), stretching the 20-liter tank to 330 km (205 miles) between fills.

Off the Beaten Path:
While the Ténéré isn’t a hardcore enduro, it handles gravel and forest trails with ease. The Dunlop Trailmax tires strike a decent compromise, though swapping to knobbies unlocks deeper off-road potential. Overheating in sand or mud is mitigated by an engine fan—a rare feature for its time.

On-Road Handling: Stable, But Not Sporty

The XTZ 660’s 1,495 mm (58.9-inch) wheelbase and 43 mm telescopic forks prioritize stability over agility. On highways, it tracks straight with minimal effort, though crosswinds can induce a slight weave above 110 km/h (68 mph). Stiffening the rear rebound damping (adjustable via a 5-way dial) tames this quirk.

The single 282 mm front disc brake lacks modern bite but provides adequate stopping power with a 4-piston caliper. The rear brake, meanwhile, offers progressive feel—perfect for modulating slides on loose surfaces.

Off-Road Capability: Know Its Limits

With 220 mm of front suspension travel and a 21-inch front wheel, the Ténéré soaks up ruts and rocks competently. However, the 200 mm rear travel and 17-inch rear wheel limit its ability in deep sand or technical singletrack. It’s best suited to fire roads and light trails, where its torque-rich engine and upright ergonomics shine.

The skid plate is a lifesaver, deflecting debris and surviving the occasional rock strike. Riders tackling tougher terrain should consider upgrading the suspension springs and adding handguards—both available at MOTOPARTS.store.

Competition: How Does It Stack Up?

The early ’90s dual-sport market was fierce. Here’s how the Ténéré fared against rivals:

1. Honda XR650L
- Pros: Lighter (144 kg / 317 lbs dry), air-cooled simplicity.
- Cons: Lower power (43 HP), no liquid cooling.
- Verdict: The XR650L is more agile off-road, but the Ténéré’s road manners and fuel range make it better for mixed use.

2. Suzuki DR650S
- Pros: Bulletproof reliability, lower seat height (885 mm / 34.8 inches).
- Cons: Less sophisticated (4-valve engine, no oil cooling).
- Verdict: The DR650 is a better commuter, but the Ténéré’s 5-valve engine feels more refined at speed.

3. BMW R80GS
- Pros: Iconic status, shaft drive, superior touring comfort.
- Cons: Heavier (206 kg / 454 lbs), complex maintenance.
- Verdict: The BMW excels on pavement and long tours, but the Ténéré is cheaper to run and more capable off-road.

Maintenance: Keeping the Legend Alive

The XTZ 660’s simplicity is a mechanic’s dream. Here’s what owners should prioritize:

1. Valve Adjustments
- Intake: 0.10–0.15 mm (0.004–0.006 in) cold
- Exhaust: 0.15–0.20 mm (0.006–0.008 in) cold
- Tip: Check every 10,000 km (6,200 miles). MOTOPARTS.store stocks shim kits for precise adjustments.

2. Oil Changes
- Use SAE 20W-40 mineral oil (2.6L without filter, 2.7L with).
- Pro Tip: Upgrade to synthetic for hotter climates.

3. Carburetor Tuning
- The stock TEIKEI Y26PV carburetor runs best with the air screw 2.5 turns out. Clean jets annually to prevent clogging.

4. Chain & Sprockets
- The 110-link chain and 15/45 sprocket combo wears quickly under heavy loads. MOTOPARTS.store offers premium X-ring chains for extended life.

5. Cooling System
- Flush with fresh coolant every 2 years. The 1.2-liter system benefits from a 60/40 water-to-coolant ratio.

6. Brake Fluid
- DOT 4 fluid absorbs moisture over time. Bleed annually for firm lever feel.
