The Yamaha Tricity 125, with its distinctive leaning multi-wheel (LMW) design, promised a new level of stability and accessibility to urban commuters. However, like any vehicle, the Tricity 125 isn't without its quirks and potential issues. This article dives deep into the common problems reported by Tricity 125 owners, offering insights, potential solutions, and a realistic look at what to expect from this unique machine.

So, What's Everyone Complaining About? Common Tricity 125 Issues

The Tricity 125, while innovative, faces several recurring issues that owners frequently discuss. These problems range from minor annoyances to more significant concerns that can impact performance and reliability. Let's break down some of the most prevalent complaints:

1. The Dreaded "Stalling" Saga:

One of the most frequently reported problems with the Tricity 125 is its tendency to stall, particularly at low speeds or when idling. This can be incredibly frustrating in stop-and-go traffic and can even pose a safety hazard.

  • Possible Causes:

    • Fuel Injection Issues: The fuel injection system might not be properly calibrated, leading to an incorrect air-fuel mixture. This is more common in colder weather or after the scooter has been sitting for a while.
    • Idle Speed Adjustment: The idle speed might be set too low. A slightly higher idle speed can often resolve stalling issues.
    • Faulty Spark Plug: A worn or fouled spark plug can prevent the engine from firing consistently, leading to stalling.
    • Dirty Throttle Body: A buildup of carbon deposits in the throttle body can restrict airflow and cause stalling, especially at idle.
    • Vacuum Leaks: Small vacuum leaks in hoses or connections can disrupt the air-fuel mixture and cause stalling.

  • Potential Solutions:

    • Check and Replace Spark Plug: This is a relatively inexpensive and easy fix that often resolves stalling problems.
    • Clean the Throttle Body: Use a throttle body cleaner to remove carbon deposits. You can find tutorials online, but if you're not comfortable doing it yourself, take it to a mechanic.
    • Adjust Idle Speed: Consult your owner's manual or a mechanic to adjust the idle speed to the recommended setting.
    • Inspect Vacuum Hoses: Check for cracks or loose connections in vacuum hoses. Replace any damaged hoses.
    • Fuel Injector Cleaning: If the problem persists, the fuel injector might need to be cleaned or replaced. This is best left to a professional.
    • ECU Remapping: In some cases, an ECU remap might be necessary to optimize the fuel injection system for your specific riding conditions.

2. Suspension Woes: A Bumpy Ride?

While the LMW design is meant to enhance stability, some riders find the suspension on the Tricity 125 to be quite stiff and unforgiving, especially on rough roads.

  • The Issue: The stock suspension, particularly the rear shock absorber, is often described as being too firm, leading to a jarring ride. This can be uncomfortable, especially on longer commutes.
  • Possible Solutions:
    • Aftermarket Shock Absorber: Replacing the stock rear shock absorber with an aftermarket unit designed for comfort can significantly improve the ride quality. Look for options with adjustable preload and damping.
    • Adjust Preload (If Applicable): Some shock absorbers have adjustable preload. Reducing the preload can soften the suspension, but be careful not to reduce it too much, as this can affect handling.
    • Progressive Springs: Consider installing progressive springs in the front forks. These springs offer a softer initial response, improving comfort on small bumps, while still providing adequate support during harder braking or cornering.
    • Check Tire Pressure: Ensure your tires are inflated to the recommended pressure. Overinflated tires can contribute to a harsher ride.

3. Performance Pains: A Lack of Oomph?

The Tricity 125 is designed for urban commuting, and its performance reflects that. However, some riders find it lacking in power, especially when carrying a passenger or riding uphill.

  • The Issue: The 125cc engine can feel underpowered, especially when accelerating from a standstill or climbing hills. This can be a concern in fast-moving traffic.
  • Possible Solutions (with caveats):
    • Variator Tuning: Optimizing the variator (CVT transmission) can improve acceleration and responsiveness. This involves changing the weights and springs within the variator. However, modifying the variator can affect fuel economy and top speed.
    • Exhaust Upgrade: An aftermarket exhaust system might offer a slight performance boost, but the gains are typically minimal. Ensure the exhaust is compliant with local regulations.
    • Air Filter Upgrade: A high-flow air filter can improve airflow to the engine, potentially resulting in a small performance increase.
    • Acceptance: The Tricity 125 is a 125cc scooter. Realistic expectations are crucial. It's not designed for high-speed cruising or carrying heavy loads.
    • Consider a Larger Displacement Model: If performance is a major concern, consider upgrading to a larger displacement scooter, such as the Tricity 155 or 300 (if available in your region).

4. LMW System Quirks: The Leaning Thing

The leaning multi-wheel (LMW) system is what makes the Tricity unique, but it can also present some challenges.

  • The Issue: Some riders report a feeling of vagueness or instability when cornering, particularly at higher speeds. The LMW system can also feel heavy or cumbersome at low speeds.
  • Possible Solutions:
    • Practice and Familiarization: The LMW system requires a different riding technique than a traditional scooter or motorcycle. Practice cornering at different speeds to become comfortable with the feel of the leaning mechanism.
    • Check LMW Linkage: Ensure the linkage and bearings in the LMW system are properly lubricated and free from excessive play.
    • Tire Pressure: Correct tire pressure is crucial for optimal handling.
    • Suspension Setup: A properly adjusted suspension can improve stability and handling.
    • Acceptance: The LMW system offers enhanced stability in some situations, but it also introduces a different feel that some riders may not prefer.

5. Electrical Gremlins: Lights and Indicators Acting Up?

Like many modern vehicles, the Tricity 125 relies heavily on its electrical system. Electrical problems can manifest in various ways, such as faulty lights, indicators, or even starting issues.

  • Possible Causes:

    • Loose Connections: Vibrations can cause electrical connections to loosen over time.
    • Corrosion: Corrosion can build up on electrical contacts, especially in damp environments.
    • Faulty Wiring: Damaged or frayed wiring can cause shorts or open circuits.
    • Battery Issues: A weak or failing battery can cause a variety of electrical problems.
    • Fuse Problems: Blown fuses can interrupt circuits and cause components to malfunction.

  • Possible Solutions:

    • Check Connections: Inspect all electrical connections for looseness or corrosion. Clean and tighten any loose connections.
    • Inspect Wiring: Look for damaged or frayed wiring. Repair or replace any damaged wires.
    • Check Fuses: Check the fuses to see if any are blown. Replace any blown fuses with the correct amperage rating.
    • Test Battery: Have the battery tested to ensure it is in good condition. Replace the battery if it is weak or failing.
    • Professional Diagnosis: If you are unable to diagnose the problem yourself, take the scooter to a qualified mechanic for electrical diagnosis.

6. Build Quality Concerns: A Few Rough Edges?

While generally reliable, some owners have reported concerns about the overall build quality of the Tricity 125, particularly with regards to plastics and fit and finish.

  • The Issue: Some owners have reported issues with flimsy plastics, rattling panels, and premature wear and tear.
  • Possible Solutions:
    • Regular Maintenance: Regular cleaning and maintenance can help prevent premature wear and tear.
    • Tighten Loose Fasteners: Periodically check and tighten any loose fasteners on the body panels.
    • Use Quality Cleaning Products: Use cleaning products specifically designed for motorcycles and scooters to avoid damaging the plastics.
    • Warranty Claims: If you experience significant build quality issues, contact your Yamaha dealer to discuss warranty options.
