Kawasaki KLR 650 (1987–2007): The Swiss Army Knife of Dual-Sport Motorcycles
Introduction
The Kawasaki KLR 650 is the motorcycle equivalent of a trusty leatherman: not the flashiest tool in the shed, but capable of handling almost anything you throw at it. Produced from 1987 to 2007 with minimal changes, this single-cylinder stalwart earned a cult following for its rugged simplicity, go-anywhere versatility, and unshakeable reliability. Whether you’re commuting through city traffic, touring backcountry highways, or picking your way through rocky trails, the KLR 650 molds itself to the task with a shrug and a throaty exhaust note. This review dives into what makes the KLR 650 a legend—and why it remains a compelling choice for riders who value substance over spectacle.
Design and Engineering: Built to Endure
At the heart of the KLR 650 lies a 651cc liquid-cooled, single-cylinder engine with a DOHC valvetrain and a Keihin CVK40 carburetor. Outputting 42–48 HP (30.7–35 kW) and 46–47 Nm (34–35 lb-ft) of torque, this mill prioritizes low-end grunt over peak power, making it a tractor-like companion for technical terrain or highway cruising. The 5-speed transmission is bulletproof, though some riders lament the occasional “bonus neutral” between gears—a quirk that becomes part of the bike’s charm over time.
The semi-double cradle steel frame strikes a balance between rigidity and flexibility, while the 21-inch front and 17-inch rear spoked wheels (shod with 90/90-21 and 130/80-17 tires, respectively) offer a confident stance on mixed surfaces. Suspension travel is generous: 230 mm (9.1 inches) at both ends, though the soft damping can lead to brake dive or wallowing under heavy loads.
Key specs:
- Dry weight: 153 kg (337 lbs)
- Seat height: 889 mm (35 inches)
- Fuel capacity: 23 liters (6.1 gallons)
- Range: 350–450 km (217–280 miles)
On-Road Performance: The Unlikely Tourer
The KLR 650 defies expectations on pavement. The upright riding position, wide handlebars, and plush seat (initially comfortable, though it softens over time) make it a surprisingly capable commuter and tourer. The fairing and windshield—basic but effective—divert windblast at highway speeds, while the rubber-mounted pegs and handlebars mitigate vibrations from the thumping single.
Highway notes:
- The engine hums contentedly at 100 km/h (62 mph), though sustained speeds above 120 km/h (75 mph) feel strained.
- Fuel efficiency averages 18.1 km/L (42.5 mpg), stretching to 25 km/L (59 mpg) with gentle throttle input.
- The single 230mm front disc brake lacks bite; upgrading to braided steel lines or a larger rotor is a popular fix.
Off-Road Capability: More Than a Poseur
The KLR 650 isn’t a dirt bike in disguise, but it’s competent enough for fire roads, gravel trails, and mild single-track. The 239 mm (9.4 inches) of ground clearance shrugs off rocks and ruts, while the long-travel suspension soaks up bumps—though heavier riders might crave stiffer springs.
Trail quirks:
- The 337-lb (153 kg) dry weight demands respect on technical terrain; drop it, and you’ll wrestle to upright it.
- The stock Dunlop K750 tires are a compromise: adequate on dirt but slippery in mud. Swapping to aggressive knobbies (like Pirelli MT21s) unlocks better grip.
- The exposed exhaust can melt luggage; aftermarket heat shields or luggage racks are wise investments.
Comfort and Ergonomics: All-Day Companion
The KLR’s ergonomics cater to a wide range of riders. The 35-inch seat height is intimidating for shorter inseams, but the narrow tank and soft suspension sag help tip-toers reach the ground. For touring, the rear rack supports soft luggage, and the tank’s sculpted sides let you grip with your knees during long slogs.
Upgrade tips:
- Seat: The stock foam collapses over time. Corbin or Seat Concepts replacements add support.
- Windshield: A taller aftermarket screen (like from Puig) reduces buffeting.
- Handguards: Barkbusters protect levers and fingers in drops.
Competition: How the KLR Stacks Up
The KLR 650’s rivals are few but fierce. Here’s how it compares:
| Model | Pros | Cons | |--------------------|-------------------------------------------|-------------------------------------------| | Suzuki DR650S | Lighter (149 kg / 328 lbs), more agile off-road | No stock fairing, shorter fuel range | | Yamaha XT600E | Punchier mid-range, air-cooled simplicity | Smaller tank, less comfortable for touring| | BMW F650GS | Fuel-injected, premium build quality | Higher cost, complex maintenance |
The KLR’s trump card is its balance: it’s more road-biased than the DR650, more durable than the XT600, and far cheaper to own than the BMW. It’s the Goldilocks of dual-sports—just right for riders who want one bike to rule them all.
Maintenance: Keep It Simple, Keep It Running
The KLR 650 thrives on neglect but rewards attention. Key maintenance points:
- Sidestand Safety Switch: Prone to failure. Bypass it with a $5 eBay dongle.
- Countershaft Sprocket: Check for seal leaks. Upgrade to a Loctite-fixed sprocket to prevent spline wear.
- Valve Adjustments: Shim-over-bucket design requires checks every 10,000 km (6,200 miles).
- Suspension: The rear shock fades on rough terrain. A rebuilt unit from Cogent Dynamics transforms handling.
MOTOPARTS.store Recommendations:
- Braided brake lines for sharper stopping.
- Skid plates and crash bars for off-road protection.
- LED headlights to replace the dim stock bulb.
Conclusion: The Everyman’s Adventure Bike
The Kawasaki KLR 650 isn’t perfect. It’s heavy, underpowered, and about as stylish as a pair of Crocs. But like those rubber clogs, it’s functional, comfortable, and damn near indestructible. For riders who value practicality over panache, the KLR remains a benchmark—a machine that invites you to explore the world without mortgaging your future. Twenty years on, it’s still the bike you ride further, longer, and with more stories to tell.
