#### **Overview**

---

### **Pros of Buying This Part**

1. **Authentic Fit and Function**

The part is manufactured by Yamaha, meaning it is designed specifically for the 1999-2000 YZF-R6/YZR6. This ensures a perfect fit without modifications, reducing the risk of leaks or improper sealing.

2. **Durability and Quality**

Yamaha parts are generally built to last, using materials that can withstand the stresses of motorcycle use, including exposure to fuel, heat, and vibration. A high-quality collar will prevent fuel or oil leaks, which can be hazardous and damaging.

3. **Easy Replacement**

Replacing a worn or damaged collar is a straightforward task that typically requires minimal tools. Many riders can do this themselves, saving on labor costs if they choose to perform the repair.

4. **Prevents Long-Term Damage**

A failing collar can lead to fuel spills, which may damage the fuel system, paint, or surrounding components. Replacing it proactively can avoid more costly repairs down the line.

5. **Availability of New Parts**

Since this is a relatively common part for older Yamaha models, it is likely to be available from Yamaha dealers, authorized service centers, or reputable aftermarket suppliers. This makes it easier to source if needed.

6. **Compatibility with Aftermarket Mods**

If you plan to modify your bike (e.g., installing an aftermarket fuel tank), an OEM collar ensures compatibility with the new part, maintaining the integrity of the seal.

---

### **Cons of Buying This Part**

1. **Age of the Model**

The YZF-R6/YZR6 from 1999-2000 is an older model, and finding a dealer that stocks original Yamaha parts for these specific years may be difficult. You might need to order online or from a specialty supplier, which could involve shipping delays.

2. **Potential for Counterfeit Parts**

Older model parts are more susceptible to counterfeit or low-quality replicas, especially if purchased from untrusted sellers. Always buy from reputable sources to avoid receiving substandard or unsafe parts.

3. **Cost Relative to Aftermarket Alternatives**

While Yamaha parts are reliable, they may be more expensive than aftermarket alternatives. Aftermarket collars from brands like **Gasket Pro, Fel-Pro, or local motorcycle-specific suppliers** might offer similar performance at a lower cost. However, ensure the aftermarket part is designed for your specific model.

4. **Limited Longevity of the Part**

Like all rubber or plastic components, collars degrade over time due to exposure to fuel, heat, and UV rays. Even a new collar may not last indefinitely, especially if the bike is ridden frequently or stored in harsh conditions.

5. **Mismatch with Later Model Upgrades**

If you ve modified your bike with parts from later model years (e.g., a 2001 fuel tank), the collar might not fit perfectly. Always verify compatibility with any upgrades before purchasing.

6. **Potential for Overkill**

If the collar is only slightly worn or the leak is minor, replacing just the collar might not be the most cost-effective solution. A thorough inspection of the surrounding components (e.g., fuel lines, tank seals) may reveal deeper issues that need addressing.

---

### **Conclusion**

The **Yamaha 90387-25024-00 collar** is a reliable, high-quality part for the 1999-2000 YZF-R6/YZR6 that ensures proper sealing and prevents leaks. Its authenticity and durability make it a strong choice for riders who prioritize long-term reliability and ease of installation. However, the challenge of sourcing it for an older model and the potential for higher costs compared to aftermarket options must be considered.

If you re experiencing a leak or suspect the collar is failing, replacing it is a prudent preventive measure. Just ensure you purchase it from a trusted supplier to avoid counterfeit parts. For those on a budget, an aftermarket alternative could be a viable option, provided it meets the same quality standards.

---

### **Recommendation**

Purchase the **Yamaha OEM collar (90387-25024-00)** from an authorized dealer or a reputable online retailer (e.g., **Motorcycle Parts 360, RockAuto, or a local Yamaha service center**). This ensures compatibility and quality.

Look for a **high-quality aftermarket collar** from brands like **Gasket Pro or Fel-Pro**, ensuring it is specified for the 1999-2000 YZF-R6/YZR6. Check reviews or consult with a mechanic to confirm its reliability.

Inspect the surrounding components (fuel lines, tank seals, clamps) for wear or damage. If the problem persists after replacement, consult a professional to diagnose any underlying issues.

Keep a spare collar on hand or set a reminder to check the fuel system periodically, especially if the bike is stored long-term or exposed to extreme conditions.

Ultimately, the **Yamaha OEM collar is the safest choice** for authenticity and performance, but aftermarket options can be explored if budget is a concern. Always prioritize quality to avoid recurring leaks or damage.
