The **Harley-Davidson 91-3660 No. 3660 Bar Handlebars** are a meticulously engineered, high-performance set of bar ends designed exclusively for the **FXR, Dyna XL, and Softail** platforms, ensuring a perfect blend of style, ergonomics, and durability. Crafted from **high-grade aircraft-grade aluminum**, these handlebars feature a **sleek, aggressive contour** that enhances rider control while maintaining a sporty yet approachable aesthetic.

Engineered with **Harley-Davidson s signature precision**, these bars incorporate **smooth, rounded grip surfaces** that offer a secure yet comfortable hold, even during aggressive maneuvers. The **anodized finish** not only resists corrosion but also adds a subtle, premium sheen that complements the motorcycle s aggressive stance. Whether paired with the **FXR s aggressive stance, the Dyna XL s sporty ergonomics, or the Softail s classic cruiser appeal**, these handlebars elevate the riding experience by delivering **superior feedback, reduced fatigue, and a more engaged connection to the bike**. Built to withstand the demands of daily riding and spirited adventures, the **91-3660 No. 3660 Bar Handlebars** are an ideal upgrade for riders seeking both performance and a bold, modern aesthetic.

### **Pros and Cons of Buying 91-3660 NOS Bar Handlebars for a Harley FXR/Dyna XL/Softail FL**

#### **Pros:**

1. **Original Equipment Quality (OEM)** The 91-3660 bar is a genuine Harley-Davidson part, meaning it was designed and built to the same high standards as the original installation. This ensures proper fitment, durability, and compatibility with the bike s frame and controls.

2. **Reliability and Longevity** Harley-Davidson parts, especially those from the early 2000s, are known for their robust construction. A NOS (New Old Stock) bar means it has never been installed or damaged, reducing the risk of wear or failure over time.

3. **Aesthetic and Brand Consistency** The 91-3660 bar matches the styling of Harley s FXR, Dyna XL, and Softail FL models from its era. If you prefer a classic look or want to maintain period-correct aesthetics, this bar fits seamlessly.

4. **Proper Ergonomics** Harley s handlebars are designed with rider comfort in mind, offering a balanced grip position that reduces strain during long rides. The bar s shape and width are optimized for the bike s intended use.

5. **Resale Value** Since it s a NOS part, it retains higher value compared to aftermarket or used replacements. If you decide to sell the bike or upgrade later, the original bar may appeal to buyers seeking authenticity.

6. **Warranty and Support** Harley-Davidson offers warranty coverage for original parts, though this may vary depending on the seller. Some NOS parts come with limited warranties or certifications from reputable dealers.

7. **Compatibility with Stock Components** The bar is designed to work seamlessly with the bike s stock controls (throttle, brake levers, turn signals, etc.), ensuring smooth operation without modifications.

8. **Reduced Risk of Modification Issues** Unlike aftermarket bars, which may require additional spacers or adjustments, the 91-3660 fits directly, minimizing potential alignment or functionality problems.

#### **Cons:**

1. **Limited Adjustability** Harley s stock bars are not adjustable for reach or rake. If you prefer a more aggressive or relaxed riding position, you may need to source aftermarket bars or spacers, which could require modifications.

2. **Weight** Harley bars, while sturdy, are heavier than some aftermarket alternatives. This can contribute to overall bike weight, though the difference is often negligible for most riders.

3. **Cost** NOS Harley parts can be expensive, especially if sourced from authorized dealers or reputable collectors. The price may be higher than aftermarket options, depending on availability and demand.

4. **Potential for Overkill** If you plan extensive modifications (e.g., lowering the bike, changing suspension, or swapping controls), the stock bar may not be the most practical choice. Aftermarket bars often offer more flexibility for custom builds.

5. **Availability and Lead Times** NOS parts can be difficult to find, particularly for older model years. Some sellers may charge premium prices due to limited stock, and delivery times could be longer than for aftermarket alternatives.

6. **Less Customization** Unlike aftermarket bars, which come in various shapes (e.g., ape hanger, low-rise, or sport bars), the 91-3660 offers no styling variations. If you want a unique look, you ll need to explore other options.

7. **Potential for Overbuilding** If you re restoring a bike to stock condition, the NOS bar is ideal. However, if you re building a custom or performance-oriented machine, the stock bar may feel restrictive.

8. **Installation Complexity** While straightforward, installing a stock bar requires proper alignment with the controls. Mismatched wiring or lever positioning can occur if not done carefully, potentially requiring adjustments.

---

### **Conclusion:**

The **91-3660 NOS bar handlebars** are an excellent choice if you prioritize **authenticity, reliability, and stock compatibility** for your Harley FXR, Dyna XL, or Softail FL. They offer the highest quality and fitment for riders who want to maintain the bike s original character or restore it to factory condition. However, if you re looking for **customization, weight savings, or ergonomic flexibility**, aftermarket alternatives may be more suitable.

For most **restoration projects or riders who prefer a classic look**, the NOS bar is a **strong recommendation**. If you re building a **modern or heavily modified bike**, weigh the pros and cons carefully especially regarding adjustability and long-term usability.

**Final Recommendation:**

- **Buy the NOS bar** if you want a **stock-sound, high-quality, and reliable** option for your Harley.

- **Consider aftermarket bars** if you need **adjustability, weight reduction, or a different riding position**.

- **Verify the part s authenticity** (check for Harley s serial numbering and condition) before purchasing to ensure you re getting a true NOS unit.
