### Pros and Cons of Buying an Aprilia RS660 660 Rear Brake Master Cylinder (Part Number: 2B007140)
#### **Pros:**1. **Compatibility and Fit:** The Aprilia RS660 660 rear brake master cylinder is an OEM (Original Equipment Manufacturer) part, meaning it is designed specifically for the RS660 model. This ensures a perfect fit without modifications, reducing the risk of installation issues or misalignment.
2. **Reliability and Performance:** Being an OEM component, it is built to the same high standards as the original part installed on the bike. This typically means better durability, smoother operation, and consistent braking performance compared to aftermarket parts that may vary in quality.
3. **Warranty Coverage:** Purchasing from an authorized dealer or Aprilia-approved supplier often includes a warranty, providing peace of mind against defects or premature failure. This can save you money on potential repairs down the line.
4. **Ease of Installation:** Since it is designed for the RS660, the master cylinder is likely to be straightforward to install, especially if you have basic mechanical skills or access to a mechanic. The lack of compatibility issues with other parts of the braking system simplifies the process.
5. **Long-Term Cost Savings:** While the upfront cost may be higher than some aftermarket alternatives, the longevity and reliability of an OEM part can reduce the need for frequent replacements or adjustments, saving money over time.
6. **Maintenance Benefits:** OEM parts are often easier to maintain and service because they are designed to work seamlessly with other components in the braking system (e.g., calipers, hoses, and fluid). This can make routine checks and servicing more efficient.

#### **Cons:**1. **Higher Upfront Cost:** OEM parts are generally more expensive than aftermarket alternatives. The price of the Aprilia RS660 rear brake master cylinder may be significantly higher, which could be a deterrent if you are on a tight budget.
2. **Limited Customization:** If you are looking to upgrade or modify your braking system for performance reasons (e.g., stiffer feel, better modulation, or enhanced stopping power), an OEM master cylinder may not offer the same level of customization as aftermarket options designed for performance tuning.
3. **Potential for Overkill:** If your original master cylinder was functioning adequately and only needed replacement due to wear or leakage, an OEM part may be more than necessary. In such cases, a high-quality aftermarket part could suffice without the added cost.
4. **Availability and Lead Times:** Depending on the supplier, OEM parts may have longer lead times or limited stock, especially if you are purchasing directly from Aprilia or an authorized dealer. This could delay your repair or upgrade project.
5. **Resale Value Impact:** If you plan to sell the bike in the future, some buyers may prefer aftermarket parts for their perceived cost savings or customization benefits. However, this is subjective and depends on the buyer s priorities.

### **Conclusion:**The decision to purchase the Aprilia RS660 660 rear brake master cylinder (2B007140) depends on your priorities, budget, and long-term goals for your bike. If you value reliability, warranty coverage, and a seamless fit with your existing braking system, the OEM part is an excellent choice. It ensures that your bike maintains its intended performance and safety standards without compromising on quality.
However, if you are on a tight budget, seeking performance upgrades, or simply replacing a part that is still functional but needs a minor fix, an aftermarket alternative might be more practical. Aftermarket parts often offer cost savings and sometimes even improved features (e.g., lighter weight, better materials) without sacrificing quality.

### **Recommendation:** - **Buy the OEM part (2B007140) if:**- You prioritize reliability, warranty, and a guaranteed fit.
- Your original master cylinder is failing or needs a full replacement.
- You want to maintain the bike s original specifications for resale or personal preference.
- You are comfortable paying a premium for peace of mind and long-term durability.
- **Consider an aftermarket alternative if:**- You are looking to save money without sacrificing quality (e.g., brands like Brembo, Magura, or reputable aftermarket manufacturers).
- You want to upgrade the braking system for better performance or modulation.
- Your original master cylinder is only partially worn and could be repaired or paired with a used OEM part.
- You are willing to research and choose a high-quality aftermarket part with good reviews and compatibility guarantees.
**Final Note:** Always ensure that any part you purchase is compatible with your bike s model and year. If possible, consult with a mechanic or Aprilia dealer to confirm the part s suitability and installation requirements. Regular maintenance of the braking system, including fluid changes and inspections, will further extend the life of your master cylinder, whether OEM or aftermarket.
