The **Harley-Davidson 46609-06 NOS (New Old Stock) Oil Lock Lower Fork Damper Tube (Left)** is a part commonly sought after by motorcycle enthusiasts, particularly for restoring or upgrading Harley-Davidson motorcycles, especially older models with hydraulic forks. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of buying a 46609-06 NOS Oil Lock Lower Fork Damper Tube (Left)**

1. **Authentic and Original**

The NOS designation means the part is new but has been stored in original packaging and condition since it was manufactured. This ensures it is genuine and unaltered, which is critical for maintaining the integrity of a classic or restored motorcycle.

2. **High Quality and Durability**

Harley-Davidson parts, even older ones, are known for their robust construction and longevity. The oil lock damper tube is designed to handle the stresses of motorcycle suspension, providing smooth and reliable operation when paired with compatible components.

3. **Compatibility with Classic Models**

This part is likely designed for specific Harley-Davidson models from the 1970s to early 1990s, particularly those equipped with hydraulic forks (e.g., Sportster, Electra Glide, or other models with similar suspension setups). NOS parts are often a perfect fit without modification, reducing the need for customization.

4. **Preservation of Vintage Value**

For collectors or restorers, using NOS parts preserves the authenticity of a vintage motorcycle. This is especially important for maintaining resale value or ensuring the bike meets show standards (e.g., for AMA or other classic motorcycle shows).

5. **Reliability for Restoration Projects**

If you are restoring a Harley-Davidson, sourcing NOS parts can simplify the process. These parts are less likely to fail prematurely compared to aftermarket or rebuilt components, as they were designed and built to Harley-Davidson s original specifications.

6. **Ease of Installation**

Since NOS parts are new (despite being old stock), they should fit seamlessly into the suspension system with minimal adjustments. This can save time and frustration compared to sourcing used or aftermarket parts that may require machining or modification.

7. **Aesthetic Appeal**

For enthusiasts who prioritize the look of a restored motorcycle, NOS parts often retain their original finish and markings, contributing to a more authentic appearance.

---

### **Cons of buying a 46609-06 NOS Oil Lock Lower Fork Damper Tube (Left)**

1. **Limited Availability and Lead Times**

NOS parts are rare and often held by collectors or specialty dealers. This can result in long wait times for delivery, especially if the part is highly sought after. Prices may also fluctuate based on demand.

2. **High Cost**

NOS parts are typically more expensive than aftermarket or rebuilt alternatives. The premium price reflects their authenticity, rarity, and the effort required to source them. For budget-conscious buyers, this can be a significant drawback.

3. **Potential for Overpaying**

Some sellers may inflate prices due to the NOS designation, especially if the part is in high demand. Buyers must research fair market value to avoid paying more than necessary.

4. **Compatibility Issues with Modified or Modernized Bikes**

If your Harley-Davidson has undergone significant modifications (e.g., modern suspension upgrades, frame changes, or aftermarket fork conversions), the NOS part may not fit or function as intended. Always verify compatibility before purchasing.

5. **Risk of Counterfeit or Misrepresented Parts**

The NOS market can be saturated with counterfeit or mislabeled parts. Buyers must purchase from reputable sellers with verifiable histories and authentication processes to avoid receiving a fake or incompatible part.

6. **Maintenance and Upkeep Challenges**

While NOS parts are durable, they may still require periodic maintenance (e.g., oil changes, seal replacements) to ensure longevity. Older parts may also be more prone to wear if the bike has high mileage or has been stored improperly.

7. **Limited Customization Options**

Unlike aftermarket parts, NOS components cannot be easily modified or upgraded. If you want to adjust suspension characteristics (e.g., stiffness, damping), you may need to pair the NOS part with other aftermarket components, which could introduce compatibility issues.

8. **Environmental and Ethical Considerations**

NOS parts are often sourced from dismantled or retired bikes, which may raise ethical concerns about parts harvesting. Some buyers may prefer aftermarket or recycled parts to avoid contributing to the dismantling of vintage motorcycles.

### **Conclusion**

The **Harley-Davidson 46609-06 NOS Oil Lock Lower Fork Damper Tube (Left)** is an excellent choice for enthusiasts who prioritize authenticity, quality, and the preservation of their motorcycle s vintage character. It is ideal for restorers, collectors, or riders who want to maintain the original integrity of their bike. However, the high cost, limited availability, and potential for overpaying or counterfeit parts make it less suitable for casual riders or those on a tight budget.

For buyers who are not committed to a full restoration or who seek flexibility in customization, aftermarket or rebuilt alternatives may offer a more practical solution. Additionally, thorough research and purchasing from trusted sources are essential to ensure you receive a genuine NOS part that meets your needs.

### **Recommendation**

- **Buy the NOS part if:**

- You are restoring a classic Harley-Davidson and authenticity is a priority.

- You have verified the part s compatibility with your specific model and suspension setup.

- You are willing to pay a premium for a high-quality, original component.

- You purchase from a reputable dealer with a track record of authentic NOS parts.

- **Consider alternatives if:**

- You are on a budget and aftermarket or rebuilt parts are sufficient for your needs.

- Your bike has been heavily modified, and compatibility with the NOS part is uncertain.

- You prioritize customization or modern performance upgrades over vintage authenticity.

- You are unable to source the part quickly due to availability issues.

Ultimately, the decision depends on your goals, budget, and commitment to preserving the original character of your Harley-Davidson. For most restorers, the NOS part is a worthwhile investment, while others may find aftermarket solutions more practical.
