The **Honda 4551AO-MM5-670 Brake Pad Kit** is a meticulously engineered aftermarket upgrade designed specifically for the **1987-1988 Honda CBR1000R**, a legendary sportbike renowned for its aggressive styling, cutting-edge technology, and high-performance capabilities. This brake pad kit represents a critical enhancement for riders seeking to maximize braking performance, safety, and longevity of their bike s braking system. Crafted from high-quality, performance-oriented materials, these pads are engineered to deliver superior friction, heat resistance, and durability, ensuring consistent stopping power even under demanding conditions. The **MM5-670** compound is a semi-metallic formulation, striking a balance between friction coefficient and wear resistance, making it ideal for high-performance sportbikes like the CBR1000R. This blend excels in wet and dry conditions, reducing brake fade and maintaining a responsive feel, which is essential for the aggressive cornering and high-speed braking demands of modern riding. The kit includes a complete set of brake pads tailored to fit the **CBR1000R s** front and rear calipers precisely, ensuring optimal contact area and even wear. Installation is straightforward, requiring no special tools beyond basic mechanical know-how, though riders with limited experience may benefit from consulting a professional. Beyond performance, these pads are designed to minimize dust and wear on rotors, preserving the original braking system s integrity and extending its service life. Whether you re a track enthusiast pushing the limits of your CBR1000R or a street rider prioritizing safety and control, this brake pad kit offers a reliable, high-performance solution that complements the bike s legendary engineering. Upgrading to this kit is a small but impactful step toward transforming your riding experience, ensuring confidence in every brake application.

### **Honda 4551AO-MM5-670 Brake Pad Kit (CBR1000R, 1987-1988) Pros and Cons**

1. **OEM Fitment** This is a direct replacement part designed specifically for the 1987-1988 Honda CBR1000R, ensuring proper alignment with the brake calipers and rotors. No modifications are typically required for installation.

2. **Reliable Performance** Honda s original brake pads were known for durability, and aftermarket kits from reputable manufacturers (assuming this is from a trusted brand) maintain similar performance standards. They provide consistent braking power and fade resistance under normal riding conditions.

3. **Cost-Effective Upgrade** Compared to full brake system overhauls (e.g., new rotors, calipers, or master cylinder), replacing just the pads is a budget-friendly way to restore braking efficiency.

4. **Easy Installation** The kit is designed for straightforward replacement, requiring only basic tools. Many riders can install it themselves without professional help.

5. **Compatibility with Stock Components** Since this is for an older CBR1000R, the kit works seamlessly with the original brake system, avoiding compatibility issues that might arise with aftermarket upgrades.

6. **Minimal Maintenance** High-quality pads reduce wear on rotors and calipers, extending the lifespan of these more expensive components.

1. **Aged Design Limitations** The 1987-1988 CBR1000R s brake system was not as advanced as later models. The pads and rotors may lack modern stopping power, especially under aggressive or high-speed braking. Riders expecting performance comparable to contemporary systems may find them underwhelming.

2. **Potential for Wear on Rotors** If the rotors are already worn or warped, replacing just the pads may not fully restore braking performance. This could require additional investment in rotor replacement.

3. **Limited Availability of Original Parts** While this kit exists, finding genuine OEM pads or high-quality aftermarket alternatives for this specific model may be challenging compared to newer bikes. Prices could be inflated due to rarity.

4. **No Modern Materials** Older brake pads often use less advanced friction materials (e.g., semi-metallic or organic compounds) compared to modern ceramic or carbon pads. This can result in less efficient heat dissipation and shorter pad life under heavy use.

5. **Rust and Corrosion Risk** If the bike has been stored for long periods, the brake system may suffer from rust or corrosion, which could affect performance even with new pads. A thorough cleaning and inspection of calipers and rotors is recommended.

6. **No Noise or Dust Improvements** Older pads tend to produce more noise and dust compared to modern alternatives, which can be a nuisance for daily riders.

### **Conclusion**

The **Honda 4551AO-MM5-670 brake pad kit** is a practical choice for restoring basic braking functionality to a 1987-1988 CBR1000R, especially if the bike is ridden lightly or used for casual riding. It offers a straightforward, cost-effective solution for those who prioritize simplicity and compatibility with the original system. However, it is not a performance upgrade expect braking performance to remain limited by the bike s aging components.

If you plan to ride aggressively, track the bike, or want modern stopping power, this kit alone will not suffice. In such cases, consider upgrading the entire brake system (e.g., aftermarket rotors, high-performance pads, and calipers) or at least replacing the rotors alongside the pads.

---

### **Recommendation**

- You need a basic, no-frills replacement for daily commuting or light riding.

- The bike s rotors and calipers are in good condition (no excessive wear, warping, or corrosion).

- You want to avoid the hassle of sourcing more expensive or specialized parts.

- You re on a tight budget and prioritize functionality over performance.

- You ride hard or want improved braking performance. In this case, pair the pads with new rotors (e.g., EBC or Brembo aftermarket options) or invest in a full brake overhaul.

- The bike shows signs of rotor wear or caliper issues. Addressing these first will maximize the effectiveness of new pads.

- You re open to modern upgrades (e.g., hydraulic brake systems, larger rotors) for better control and safety.

For the best results, pair this kit with a thorough inspection of the brake system clean calipers, check for rust, and ensure rotors are within specification. If possible, source pads from a reputable aftermarket brand (e.g., EBC, Hawk, or Akebono) that specializes in classic motorcycle parts for slightly better performance than OEM.
