### **Pros and Cons of buying a Smiths 4001/00B (SSM4001/00B) Speedometer (1600 Trip, BSA A65 Lightning NOS)**

#### **Pros:**

1. **Authentic NOS (New Old Stock) Condition** This speedometer is a genuine, never-used unit from a classic BSA A65 Lightning, making it highly desirable for enthusiasts seeking original parts for restoration or display.

2. **High Historical Value** As a NOS component from a legendary British motorcycle, it holds significant collector s value, especially if the bike is rare or well-preserved.

3. **Functional and Reliable** The Smiths 4001/00B is a well-engineered unit known for durability, with a mechanical trip meter that provides accurate readings over long distances.

4. **Aesthetic Appeal** The classic dial design, including the 1600-mile trip meter, adds to the vintage charm of a BSA A65 Lightning, making it a sought-after cosmetic piece for restorers.

5. **Compatibility** Designed specifically for the BSA A65 Lightning, it fits seamlessly with other NOS components, enhancing the bike s authenticity.

6. **Resale Potential** If well-preserved, a NOS Smiths speedometer can retain or even appreciate in value, making it a smart investment for collectors.

#### **Cons:**

1. **High Cost** NOS parts, especially from iconic bikes like the BSA A65 Lightning, command premium prices. This speedometer may be significantly more expensive than a modern or used replacement.

2. **Limited Availability** Finding a genuine NOS Smiths speedometer in perfect condition can be difficult, requiring patience and potentially higher bidding in specialized markets.

3. **Maintenance Requirements** Analog speedometers, even NOS units, may require occasional calibration or repair if mishandled, especially if exposed to moisture or mechanical stress.

4. **Potential for Counterfeits** Due to its desirability, there is a risk of encountering fakes or restored units posing as NOS. Buyers must verify authenticity carefully.

5. **Modern Alternatives Exist** While NOS parts are ideal for purists, modern replicas or aftermarket speedometers may offer similar functionality at a fraction of the cost, though without the same historical value.

6. **Installation Complexity** If the bike is being restored, ensuring proper wiring and alignment of the speedometer may require mechanical expertise, adding labor costs.

7. **Overkill for Casual Use** If the BSA A65 Lightning is primarily used for leisure rides rather than restoration, the high cost of a NOS speedometer may not justify the investment.

### **Conclusion:**

The Smiths 4001/00B NOS speedometer is a **premium choice** for BSA A65 Lightning enthusiasts who prioritize authenticity, historical value, and classic aesthetics. It is ideal for **restorers, collectors, or riders who appreciate the nostalgia of original components**. However, its **high cost, limited availability, and maintenance needs** make it less suitable for casual riders or those seeking a budget-friendly solution.

For **budget-conscious buyers**, a high-quality modern replica or a well-maintained used NOS unit might offer a more practical alternative. For **serious collectors and restorers**, the investment is justified by the unit s rarity and the enhanced authenticity it provides to the bike.

### **Recommendation:**

- **Buy if:** You are restoring a BSA A65 Lightning to showroom condition, prioritize NOS parts, and have the budget to support it.

- **Consider alternatives if:** You are on a tighter budget, the bike is primarily for riding rather than display, or you prefer modern convenience without sacrificing performance.

- **Verify authenticity carefully** before purchasing to avoid counterfeit units. Consult trusted dealers, forums (e.g., BSA Motorcycle Club), or restoration experts to confirm the unit s condition and provenance.
