The Honda Transalp 700, a versatile middleweight adventure touring motorcycle, has earned a loyal following for its reliability and comfortable ride. However, like any machine, it's not without its quirks. While generally robust, certain issues have surfaced over the years, becoming common talking points among Transalp 700 owners. Understanding these potential problems allows prospective buyers and current owners to be proactive in maintenance and troubleshooting, ensuring many more miles of enjoyable riding.

So, What Are the Common Gripes About the Transalp 700?

Let's dive into some of the most frequently discussed problems encountered by Transalp 700 riders. We'll explore each issue in detail, offering insights into potential causes and possible solutions.

1. Fuel Pump Woes: A Stalling Headache

Perhaps the most widely reported issue with the Transalp 700 is fuel pump failure. This often manifests as intermittent stalling, particularly when the bike is hot or under load. The engine might cut out suddenly, leaving you stranded.

  • The Culprit: The root cause is often attributed to the design of the fuel pump itself. The internal components, particularly the electrical contacts, can degrade over time, leading to reduced fuel delivery pressure. Heat exacerbates the problem.
  • Symptoms to Watch For:
    • Sudden stalling, especially when hot.
    • Difficulty starting, particularly after the bike has been running.
    • Hesitation or poor throttle response.
    • A whining or buzzing sound from the fuel pump.
  • What You Can Do:
    • Fuel Pump Replacement: The most reliable solution is to replace the fuel pump with an aftermarket unit known for its improved reliability. Many owners opt for pumps from brands like Facet or Quantum.
    • Relay Upgrade: Consider upgrading the fuel pump relay. A failing relay can contribute to voltage drops, stressing the fuel pump.
    • Fuel Filter Check: Ensure the fuel filter is clean. A clogged filter can put extra strain on the pump.
    • Wiring Inspection: Inspect the wiring harness connected to the fuel pump for any signs of damage or corrosion.

2. Voltage Regulator/Rectifier Issues: Keeping the Battery Happy

Another common electrical gremlin is related to the voltage regulator/rectifier (VRR). This component regulates the voltage going to the battery and other electrical systems. Failure can lead to overcharging or undercharging, both of which can damage the battery and other components.

  • Why It Happens: The VRR is often mounted in a location with poor airflow, leading to overheating. Over time, this heat can cause the internal components to fail.
  • Spotting the Problem:
    • Battery constantly dying or requiring frequent charging.
    • Overcharging the battery (indicated by a boiling or hissing sound from the battery).
    • Blown fuses.
    • Erratic electrical behavior (e.g., dimming lights, malfunctioning instruments).
  • Fixing It:
    • VRR Replacement: The most straightforward solution is to replace the VRR with an upgraded aftermarket unit. Look for units with improved cooling fins or a more robust design.
    • Relocation: Consider relocating the VRR to a cooler location with better airflow. This can significantly extend its lifespan. Some owners mount it under the seat or in a more exposed area.
    • Wiring Check: Inspect the wiring harness connected to the VRR for any signs of damage or corrosion.

3. ABS Problems: A Brake on Confidence

The ABS (Anti-lock Braking System) on the Transalp 700 can sometimes throw a wrench in the works. ABS malfunctions can range from intermittent warning lights to complete ABS failure.

  • Possible Causes:
    • Sensor Issues: The ABS sensors on the wheels can become dirty or damaged, leading to inaccurate readings.
    • Wiring Problems: Damaged or corroded wiring to the ABS sensors or the ABS control unit can cause malfunctions.
    • Low Battery Voltage: A weak battery can sometimes interfere with the ABS system's operation.
  • Signs of Trouble:
    • ABS warning light illuminating on the dashboard.
    • ABS engaging prematurely or not engaging at all.
    • Erratic braking behavior.
  • Troubleshooting Steps:
    • Sensor Cleaning: Clean the ABS sensors on the wheels with a soft cloth.
    • Wiring Inspection: Inspect the wiring harness connected to the ABS sensors and the ABS control unit for any signs of damage or corrosion.
    • Battery Check: Ensure the battery is fully charged and in good condition.
    • ABS Reset: Consult the owner's manual for instructions on how to reset the ABS system.
    • Professional Diagnosis: If the problem persists, it's best to take the bike to a qualified mechanic for diagnosis and repair. They will have the necessary tools and expertise to diagnose complex ABS issues.

4. Exhaust System Corrosion: The Rust Never Sleeps

The exhaust system on the Transalp 700, particularly the headers, is susceptible to corrosion, especially in areas with harsh weather conditions or where road salt is used.

  • Why It Happens: The exhaust system is exposed to high temperatures and moisture, creating a perfect environment for rust to form.
  • What to Look For:
    • Visible rust on the exhaust headers and other exhaust components.
    • Exhaust leaks.
    • A rattling sound from the exhaust system.
  • Fighting the Rust:
    • Regular Cleaning: Regularly clean the exhaust system with a motorcycle-specific cleaner to remove dirt and grime.
    • Protective Coating: Apply a high-temperature protective coating to the exhaust headers to prevent rust.
    • Replacement: If the corrosion is severe, the exhaust system may need to be replaced. Consider upgrading to a stainless steel exhaust system for improved durability.

5. Suspension Sag: Feeling the Weight

The stock suspension on the Transalp 700 is often criticized for being too soft, especially for heavier riders or those carrying luggage. This can lead to excessive sag, poor handling, and bottoming out on rough roads.

  • The Issue: The stock springs are often not stiff enough to handle the weight of the rider, passenger, and luggage.
  • Symptoms:
    • Excessive sag when the rider sits on the bike.
    • Poor handling and stability, especially in corners.
    • Bottoming out on rough roads.
  • Improving the Ride:
    • Spring Upgrade: Replace the stock springs with stiffer springs that are appropriate for your weight and riding style.
    • Fork Oil Change: Change the fork oil to a higher viscosity oil to improve damping.
    • Rear Shock Replacement: Consider replacing the rear shock with an aftermarket unit that offers adjustable damping and preload.

6. Side Stand Switch Issues: A Safety Cutoff

The side stand switch, designed to prevent riding with the side stand down, can sometimes malfunction, causing the engine to cut out unexpectedly.

  • The Problem: The switch can become dirty, corroded, or damaged, leading to false signals.
  • Signs of Trouble:
    • Engine cutting out when the side stand is up.
    • Difficulty starting the bike.
  • Fixing It:
    • Cleaning: Clean the side stand switch with a contact cleaner.
    • Adjustment: Adjust the position of the switch to ensure it is making proper contact.
    • Replacement: If cleaning and adjustment don't work, the switch may need to be replaced.
    • Bypass (Use with Caution): In some cases, riders choose to bypass the side stand switch altogether. However, this is a safety risk and should only be done as a temporary measure. Always ensure the side stand is up before riding.
