### Yamaha PZ-VT500 (2007 2018) Pros and Cons of buying a Inside A-Arm Collar (Part Numbers: 90387-10057-00, 90387-10057, 90387-10074)

---

#### **Pros**

1. **Reliability and Durability**

The Yamaha PZ-VT500 is widely regarded as one of the most reliable and long-lasting motorcycles in its class. The engine, a 499cc parallel-twin, is known for its robustness, especially when maintained properly. Many units easily exceed 100,000 miles with regular upkeep. The VT500 s simplicity fewer electronic components compared to modern bikes reduces the risk of complex failures.

2. **Proven Performance**

The engine delivers consistent power (around 37 40 hp) and torque, making it suitable for both city commuting and light touring. The VT500 s powerband is forgiving, and the clutch and transmission are durable if not abused. The bike s weight (around 380 400 lbs) provides stability at speed, and the parallel-twin layout offers smooth power delivery without the complexity of a V-twin or inline-four.

3. **Low Maintenance Costs**

Compared to modern bikes with advanced electronics, fuel injection, or complex suspension systems, the VT500 is inexpensive to maintain. Basic upkeep (oil changes, chain adjustments, valve checks) is straightforward and affordable. Parts are widely available, and labor costs are minimal. The absence of a catalytic converter or strict emissions requirements (in most regions) further reduces maintenance hassle.

4. **Simplicity and Ease of Repair**

The VT500 s design is straightforward, with a focus on functionality over frivolity. Mechanics and DIY enthusiasts appreciate its accessibility components like the carburetors (if not upgraded to fuel injection), clutch, and suspension are easy to service. The lack of advanced diagnostics means fewer trips to the shop for code-related issues.

5. **Resale Value and Community**

The PZ-VT500 holds its value surprisingly well for a bike in this class, especially given its age. There s a strong owner community, with forums (e.g., Yamaha VT500 forums, Cycle World) offering troubleshooting advice, modifications, and restoration tips. This community also means a steady supply of used parts and aftermarket support.

6. **Versatility**

- **Commuting**: Comfortable ergonomics, decent fuel economy ( 60 70 mpg), and a practical riding position.

- **Touring**: With aftermarket panniers and a windscreen, it can handle weekend trips comfortably.

- **Modifications**: The bike is popular for upgrades like fuel injection (e.g., Yamaha s own YSSI or aftermarket systems like Walbro), suspension tuning, and exhaust modifications. The stock engine can be pushed with relative ease.

7. **Weather Resistance**

The VT500 s bodywork is simple but effective, with a full fairing that provides decent wind protection. The seat is comfortable for long rides, and the bike s weight helps it stay stable in crosswinds.

8. **Cost-Effective Ownership**

Fuel, insurance, and registration costs are among the lowest for a bike in its category. The lack of advanced features also means no expensive upgrades are required to keep it running.

---

#### **Cons**

1. **Outdated Technology**

The VT500 is a carbureted bike (though some later models may have been equipped with Yamaha s YSSI fuel injection system, which is basic by modern standards). Carburetors require regular tuning and can be finicky in varying conditions (e.g., humidity, altitude). Fuel injection would improve reliability and performance but is an expensive upgrade.

- Note: The **inside A-arm collar** (part numbers 90387-10057-00, 90387-10057, 90387-10074) is part of the front suspension system. If these are worn or damaged, it can lead to handling issues like excessive play or a "soft" front end. Replacing them is a straightforward DIY job but highlights the bike s aging suspension.

2. **Handling Limitations**

The VT500 s suspension is basic and not as refined as modern bikes. The front fork (a 41mm cartridge fork) and rear shock are adequate for light use but can feel stiff or worn after high mileage. The bike s weight distribution and geometry make it less nimble than sportier bikes, and aggressive cornering can feel tiring.

- The **A-arm collars** are critical for maintaining proper fork alignment. Worn collars can cause the fork to bind or misalign, leading to poor handling or even fork damage. This is a common wear item that may need replacement if the bike has seen significant mileage.

3. **Comfort for Long Rides**

While the VT500 is comfortable for casual riding, it lacks the ergonomic refinements of modern touring bikes. The seat is firm, and the footpegs may not accommodate all riders preferences. Without aftermarket modifications (e.g., a taller seat, ergonomic grips), long rides can become fatiguing.

4. **Noise and Vibration**

The parallel-twin engine is loud, especially at higher RPMs, and the lack of sound insulation means cabin noise is noticeable. Vibration levels can be high at certain RPMs, which may lead to discomfort over time. While not dangerous, this can be a drawback for riders sensitive to noise or vibration.

5. **Fuel Economy Variability**

The VT500 s fuel economy is decent but not exceptional. In city traffic, it can achieve 60 70 mpg, but on highways, it may drop to 50 60 mpg, depending on riding style and conditions. This is better than many modern bikes but not as efficient as a scooter or a smaller displacement bike.

6. **Aftermarket Parts Availability**

While parts are widely available, some aftermarket components (e.g., high-quality suspension, exhaust systems, or ergonomic upgrades) may require sourcing from third-party vendors. Yamaha s official parts can be expensive, and some specialized upgrades may not be as refined as those for more popular bikes (e.g., Honda CB500F).

7. **Safety Features**

- Traction control

- ABS (though some aftermarket ABS kits exist)

- Advanced rider aids (e.g., slipper clutch, quickshifter)

These features are not critical for casual riding but can be appealing for riders seeking more confidence in all conditions.

8. **Resale Depreciation**

While the VT500 holds its value better than many bikes, it will still depreciate over time. If you plan to sell it in the future, the resale value may not match the cost of upgrades or maintenance.

#### **Specific Notes on the Inside A-Arm Collar (90387-10057-00, 90387-10057, 90387-10074)**

- **Excessive fork play**: The fork may move too much laterally, causing a "loose" or "soft" front end.

- **Misalignment**: Worn collars can cause the fork to lean or bind, affecting handling and potentially damaging the fork seals.

- **Noise**: A worn collar may produce a clunking or rattling noise when riding over bumps.

- These are relatively inexpensive to replace (typically $20 $50 per collar, depending on brand).

- Replacement is a straightforward DIY job if you have basic mechanical skills. You ll need to remove the front wheel, fork, and fairing to access the collars.

- If the collars are worn, replacing them is a wise investment to restore proper fork function and handling.

- Ensure you get the correct part numbers (90387-10057-00 is the original Yamaha part, while 90387-10057 and 90387-10074 may be aftermarket or slightly different variants). Always verify compatibility with your bike s year and configuration.

### **Conclusion**

The Yamaha PZ-VT500 (2007 2018) is an excellent choice for riders seeking a **reliable, low-maintenance, and affordable** motorcycle that can handle commuting, light touring, and modifications.
