Buying **EBC MN/M7S2 rear semi-sintered brake pads** for a **1986-1987 Harley-Davidson FXRS-SP/KX** has both advantages and drawbacks, depending on your priorities performance, longevity, cost, and compatibility. Below is a detailed breakdown.
### **Pros of EBC MN/M7S2 Brake Pads**
1. **Proven Performance for Harley-Davidson Bikes**
EBC is a well-regarded manufacturer with a history of producing reliable brake components for motorcycles, including Harley-Davidsons. Their semi-sintered pads are designed to provide a good balance between stopping power and durability, which is critical for Harley s heavier rear-wheel setups.
2. **Decent Stopping Power for the Rear Wheel**
While Harley s rear brakes are traditionally weaker than the front, these pads offer improved friction compared to stock OEM pads, providing better modulation and response. This can be particularly useful in stop-and-go traffic or when carrying heavier loads.
3. **Moderate Noise and Dust Levels**
Semi-sintered pads from EBC are generally quieter than ceramic pads and produce less dust than organic pads. This makes them a practical choice for daily riding without excessive maintenance concerns.
4. **Affordable Compared to High-End Options**
EBC pads are more budget-friendly than premium brands like Nissin, Hawk, or Brembo, making them a cost-effective upgrade for riders who want better brakes without overspending.
5. **Compatibility with Stock Harley Brake Systems**
These pads are designed to fit the **1986-1987 FXRS-SP/KX** without requiring major modifications to the caliper or rotor. They should bolt on directly, assuming the rotors are in good condition.
6. **Good for General Riding Conditions**
If you primarily ride in urban or highway environments with moderate braking demands, these pads will perform adequately without requiring frequent replacements.
### **Cons of EBC MN/M7S2 Brake Pads**
1. **Limited Stopping Power Compared to Modern Pads**
Harley s rear brake system was never designed to be a primary stopping mechanism, and even upgraded pads like these will not match the performance of a high-quality front brake setup. For aggressive braking or heavy loads, the rear pads will still feel underpowered.
2. **Shorter Lifespan Than Premium Pads**
While EBC pads are durable, they may wear out faster than higher-end semi-metallic or ceramic pads, especially if you ride aggressively or in wet conditions. This could lead to more frequent replacements and added maintenance costs over time.
3. **Potential for Brake Dust Buildup**
Semi-sintered pads generate more dust than ceramic pads, which can accumulate on the rotor and caliper, reducing efficiency over time. Regular cleaning may be necessary to maintain optimal performance.
4. **Noisy Under Heavy Braking**
Some riders report a slight squeal or chatter when applying firm rear braking, which can be annoying in stop-and-go traffic. This is more noticeable than with ceramic pads but less intrusive than organic pads.
5. **Not Ideal for High-Performance or Custom Setups**
If you ve modified your bike with heavier rear suspension, a larger rear tire, or a performance exhaust, these pads may not provide sufficient stopping power. In such cases, upgrading to a more aggressive pad compound (e.g., EBC s M7S2 is semi-sintered but not as hard as some alternatives) could still fall short.
6. **Limited Availability of Aftermarket Upgrades**
Harley s rear brake system lacks the aftermarket support of modern bikes. If you later decide to upgrade to a more powerful front brake system (e.g., a dual-disc setup), the rear pads may become less relevant, making this an incremental improvement rather than a major upgrade.
### **Conclusion**
The **EBC MN/M7S2 semi-sintered brake pads** are a **practical, mid-range upgrade** for the **1986-1987 FXRS-SP/KX** if your primary goals are:- **Improved rear braking feel** over stock pads without a significant investment.
- **Reliable, low-maintenance performance** for everyday riding.
- **A balance between cost and performance**, avoiding the noise and dust issues of cheaper organic pads.
However, they are **not a game-changer** for the rear brake system, which remains the weakest link in Harley s braking setup. If you frequently carry heavy loads, ride aggressively, or prioritize maximum stopping power, you may want to consider:
- **Upgrading the front brakes** (e.g., dual-disc conversion) for the most significant safety improvement.
- **Investing in higher-end rear pads** (e.g., Hawk HPS or Nissin Ceramet) if you want longer lifespan and quieter operation.
- **Pairing these pads with a high-quality rotor** (e.g., a drilled/slotted aftermarket rotor) to improve heat dissipation and braking efficiency.
### **Recommendation**
For the **1986-1987 FXRS-SP/KX**, the **EBC MN/M7S2 pads are a solid, budget-friendly choice** if you want better rear braking than stock without breaking the bank. They are a **good middle ground** for riders who prioritize practicality over extreme performance.
If you can afford it, **pairing these with a front brake upgrade** (e.g., a dual-disc conversion) would yield far greater safety benefits. If you re satisfied with your current front brakes and just want a subtle improvement in the rear, these pads will serve you well for moderate riding.
**Final Verdict:** *Buy them if you want a noticeable but not revolutionary upgrade for the rear brake. If you re serious about safety, focus on the front first.*
