**Pros and Cons of buying a Motion Pro MN/857H Speedometer Cable for a 1980 Suzuki SP400 Control Unit**

### **Pros:**

1. **Compatibility** The Motion Pro MN/857H is designed specifically for the Suzuki SP400, ensuring a direct fit with the control unit and speedometer wiring harness. This reduces the risk of compatibility issues that can arise with generic or aftermarket parts.

2. **Quality Construction** Motion Pro products are generally built to last, using durable materials that resist corrosion and wear. This can extend the lifespan of your speedometer and wiring system, especially in a classic bike where original components may degrade over time.

3. **Reliability** Since the cable is a direct replacement, it should function as intended without requiring modifications. This is particularly useful if your original cable has failed due to fraying, rust, or internal damage.

4. **Ease of Installation** The cable is likely designed to be a straightforward drop-in replacement, meaning you won t need extensive modifications to your wiring or control unit. This saves time and reduces the risk of damaging other components during installation.

5. **Support for Classic Motorcycles** Motion Pro specializes in parts for older bikes, so their products are often tested and optimized for vintage models like the SP400. This means they re less likely to introduce compatibility issues compared to generic or poorly researched aftermarket parts.

6. **Potential Cost Savings** If the cable is the only failing component in your speedometer system, replacing just this part can be cheaper than overhauling the entire speedometer or control unit. It may also prevent more serious electrical issues down the line.

### **Cons:**

1. **Cost** While not excessively expensive, a specialized cable like this may still be more costly than a generic or DIY solution. If you re on a tight budget, you might consider alternatives like reusing a salvaged cable from a junkyard bike or attempting repairs on the existing one.

2. **Availability and Lead Time** Depending on where you purchase it, the cable might not be in stock immediately. Some specialty suppliers may require pre-ordering, which could delay repairs if you re in a hurry.

3. **Potential for Counterfeit or Low-Quality Copies** If buying from an unverified seller (e.g., third-party online marketplaces), there s a risk of receiving a counterfeit or inferior replica. Always purchase from reputable dealers or authorized Motion Pro distributors to avoid this.

4. **Limited Customization** If your speedometer or control unit has been modified (e.g., with aftermarket gauges or wiring), the MN/857H may not account for those changes. You might need additional adapters or modifications to ensure proper function.

5. **Warranty Limitations** Some aftermarket parts, including Motion Pro items, may come with limited warranties or no warranty at all. If the cable fails shortly after purchase, you may be responsible for replacement costs.

6. **Overkill for Minor Issues** If your speedometer s problems stem from something other than the cable (e.g., a faulty control unit, bent needle, or damaged wiring elsewhere), replacing just the cable won t resolve the underlying issue. A thorough diagnosis is essential before purchasing.

### **Conclusion:**

The Motion Pro MN/857H speedometer cable is a **strong, reliable choice** for a 1980 Suzuki SP400 if your speedometer is malfunctioning due to a faulty cable. Its compatibility, durability, and ease of installation make it a practical solution for restoring proper speedometer function without major modifications. However, it s not without drawbacks primarily the cost, potential lead times, and the need to ensure the issue is isolated to the cable itself.

If you re confident that the cable is the root cause of your speedometer problems and you value quality and longevity, this is a **highly recommended** part. For budget-conscious riders or those with more complex wiring issues, a diagnostic check to confirm the exact problem (e.g., testing the control unit or other connections) may be worthwhile before committing to the purchase.

**Final Recommendation:** Purchase the Motion Pro MN/857H cable if:

- Your speedometer is not working due to a suspected bad cable.

- You want a direct, high-quality replacement with minimal risk of compatibility issues.

- You re willing to pay a slightly premium for a specialized, reliable part.

Avoid it if:

- You suspect other components (e.g., control unit, wiring harness) are faulty and need addressing.

- You re working with a tight budget and can source a used or salvaged cable instead.

- You re unsure about the installation process and lack confidence in DIY repairs.

For the best results, pair this purchase with a thorough inspection of your speedometer system to ensure no other issues exist. If possible, consult a motorcycle electrician or a Suzuki specialist for guidance.
