The Honda Deauville 650, also known as the NT650V, was a popular touring motorcycle known for its reliability, comfort, and integrated panniers. However, like any machine, it wasn't without its quirks. While generally a dependable bike, prospective buyers and current owners should be aware of some common problems that can arise, ensuring they can keep their Deauville running smoothly for years to come.

So, What Are the Most Common Deauville 650 Issues?

Let's dive straight into the areas where the Deauville 650 sometimes shows its age. These aren't necessarily deal-breakers, but knowing about them upfront can save you time, money, and frustration.

1. The Dreaded Regulator/Rectifier (Reg/Rec) Failure

This is arguably the most frequently reported issue with the Deauville 650. The regulator/rectifier, responsible for converting AC voltage from the alternator to DC voltage for the battery and regulating the voltage to prevent overcharging, is prone to failure.

  • Symptoms: A dead battery, dimming lights, or the bike simply cutting out while riding are telltale signs. You might also notice the battery overheating or boiling.
  • Why it happens: The original Reg/Rec unit is often undersized and poorly located, leading to overheating and eventual failure.
  • The fix: The best solution is to replace the original unit with an upgraded, more robust regulator/rectifier. Many owners opt for MOSFET-type regulators, known for their efficiency and cooler running temperatures. Relocating the new unit to a cooler location, away from the engine heat, is also recommended.

2. The Clutch Can Be a Little... Temperamental

While not a catastrophic failure, the Deauville 650's clutch can sometimes feel heavy or grabby, especially when cold.

  • Symptoms: Difficulty finding neutral, jerky engagement, or a heavy lever pull are common complaints.
  • Why it happens: The clutch cable can become stretched or corroded over time, leading to increased friction. The clutch plates themselves can also wear, causing slippage or jerky engagement.
  • The fix: Start with the simple things: lubricate the clutch cable thoroughly. If that doesn't improve things, consider replacing the cable. If the problem persists, it's likely time for new clutch plates.

3. Exhaust System Corrosion: A Rust Story

The exhaust system, particularly the downpipes, is susceptible to corrosion, especially in areas where the bike is exposed to salt (road salt in winter, for example).

  • Symptoms: Visible rust, exhaust leaks, and a louder exhaust note. In severe cases, the exhaust system can develop holes.
  • Why it happens: The exhaust system is constantly exposed to high temperatures and the elements, making it vulnerable to rust.
  • The fix: Regular cleaning and application of a high-temperature anti-corrosion coating can help prevent rust. For existing rust, you can try cleaning and treating the affected areas, but in many cases, replacement of the corroded sections is necessary. Stainless steel aftermarket exhausts are a more durable, albeit more expensive, option.

4. Fuel Pump Issues: A Potential Stalling Hazard

While not as widespread as the Reg/Rec issue, the fuel pump can occasionally fail, leading to starting problems or the engine cutting out while riding.

  • Symptoms: Difficulty starting, especially when the bike is hot, or the engine suddenly stalling while riding. You might also hear a weak or unusual sound from the fuel pump.
  • Why it happens: The fuel pump is an electrical component that can wear out over time. Contamination in the fuel tank can also damage the pump.
  • The fix: The fuel pump can be tested for proper operation. If it's faulty, replacement is the only option. Installing an inline fuel filter can help prevent future problems.

5. Electrical Gremlins: The Usual Suspects

Like many older motorcycles, the Deauville 650 can suffer from various electrical issues, often related to corroded connectors or damaged wiring.

  • Symptoms: Intermittent lighting problems, malfunctioning instruments, or starting issues.
  • Why it happens: Vibration, exposure to the elements, and simply age can cause electrical connections to corrode or wires to become damaged.
  • The fix: A thorough inspection of the wiring harness and connectors is crucial. Clean and protect any corroded connections with dielectric grease. Repair or replace any damaged wires.

6. Pannier Latch Woes: A Common Annoyance

The integrated panniers are a great feature, but the latches that secure them can sometimes be a source of frustration.

  • Symptoms: Panniers that are difficult to open or close, or that don't latch securely.
  • Why it happens: The latches can become stiff or corroded over time. The plastic components can also become brittle and break.
  • The fix: Lubricating the latches with WD-40 or a similar lubricant can often improve their operation. If the latches are damaged, replacement parts are available.

7. Fork Seal Leaks: A Suspension Issue

The front fork seals can leak, leading to reduced suspension performance and potential damage to the front brakes.

  • Symptoms: Visible oil leaking from the front forks, a spongy front suspension, or reduced braking performance.
  • Why it happens: The fork seals are exposed to dirt and debris, which can damage them over time.
  • The fix: Replacing the fork seals is necessary. It's also a good idea to replace the fork oil at the same time.

8. Cooling System Concerns: Keeping it Cool

Although generally reliable, the cooling system can sometimes develop leaks or become clogged.

  • Symptoms: Overheating, coolant leaks, or a lack of heat from the engine.
  • Why it happens: Hoses can become brittle and crack, the radiator can become clogged with debris, or the water pump can fail.
  • The fix: Regularly inspect the cooling system for leaks. Flush the system and replace the coolant every two years. Replace any damaged hoses or components.

Keeping Your Deauville Happy: Preventative Maintenance is Key

The best way to avoid these problems is to perform regular preventative maintenance. Here are a few tips:

  • Regular Oil Changes: Don't skimp on oil changes. Use a good quality oil and filter and change them according to the manufacturer's recommendations.
  • Keep it Clean: Regularly wash and wax your Deauville to protect it from the elements. Pay particular attention to the exhaust system and electrical connections.
  • Check the Fluids: Regularly check the coolant, brake fluid, and clutch fluid levels. Top them up as needed and replace them according to the manufacturer's recommendations.
  • Lubricate: Lubricate the clutch cable, throttle cable, and brake levers regularly.
  • Inspect Regularly: Take the time to inspect your Deauville for any signs of wear or damage. Catching problems early can prevent them from becoming more serious.
  • Battery Maintenance: Keep the battery terminals clean and tight. Use a battery tender if you're not going to be riding the bike for an extended period.
