Review HONDA Rear Swingarm Bearings fits GOLDWING GL1800

The **Honda 52100-MCA-A20 GL1800 Gold Wing Rear Swingarm Bearings** are a precision-engineered, high-performance replacement component designed exclusively for the iconic Honda GL1800 Gold Wing touring motorcycle, ensuring smooth operation, durability, and reliability for extended rides. These bearings are meticulously crafted to meet Honda s stringent quality standards, featuring a robust **sealed ball bearing assembly** that incorporates a robust steel cage and high-grade chrome steel balls, all housed within a corrosion-resistant housing. Engineered to withstand the demanding stresses of long-distance touring, these bearings are designed to minimize friction, reduce wear on the swingarm pivot, and maintain optimal alignment of the rear suspension system, which is critical for both comfort and handling. The **A20 designation** indicates a specific bearing type optimized for the Gold Wing s rear swingarm pivot, where it interfaces with the swingarm bracket and the frame s pivot point, ensuring seamless articulation and resistance to lateral forces during aggressive cornering or high-speed cruising. Constructed from **high-carbon steel** with a polished, hardened surface, these bearings are treated with a protective coating to resist rust, oil degradation, and premature fatigue, making them ideal for riders who demand performance in diverse environmental conditions from humid coastal routes to arid desert highways. Installation is straightforward, requiring only basic tools, and the bearings are pre-lubricated with Honda-approved grease to ensure immediate functionality upon fitment. Whether replacing worn-out original components or upgrading for enhanced durability, these bearings are a critical upgrade for maintaining the Gold Wing s legendary reliability, ensuring that every mile ridden is met with the same confidence and smoothness as the day the bike was new.

### **Pros and Cons of buying a Honda 52100-MCA-A20 GL1800 Goldwing Rear Swingarm Bearings**

1. **OEM Quality and Compatibility** These are genuine Honda parts designed specifically for the GL1800 Goldwing, ensuring a perfect fit and reliable performance. Using OEM components reduces the risk of compatibility issues that can arise with aftermarket parts.

2. **Durability and Longevity** Honda s manufacturing standards are known for high-quality materials and precision engineering. These bearings are built to withstand the stress of daily riding, reducing the likelihood of premature failure.

3. **Reliability** The Goldwing is a high-mileage, high-performance motorcycle, and its swingarm bearings are critical for smooth operation. OEM bearings are tested under rigorous conditions, providing confidence in their ability to handle the demands of long rides and heavy loads.

4. **Ease of Installation** Since these are the original parts, they are designed to work seamlessly with the existing hardware. This can simplify the replacement process, especially for mechanics or riders with mechanical experience.

5. **Warranty Coverage** Purchasing from an authorized dealer or Honda-approved supplier may include warranty protection, offering peace of mind in case of defects or early wear.

6. **Maintenance Consistency** Using OEM parts helps maintain the motorcycle s original specifications, which can be important for resale value and long-term reliability. It also ensures that the bike remains within manufacturer-recommended maintenance intervals.

7. **Reduced Risk of Voiding Warranty** Modifying a motorcycle with non-OEM parts can sometimes void its factory warranty. Using genuine Honda parts avoids this risk, especially if the bike is still under warranty.

1. **Higher Cost** OEM parts are typically more expensive than aftermarket alternatives. The price of these bearings may be significantly higher, which could be a deterrent for budget-conscious buyers.

2. **Limited Availability** Genuine Honda parts may not always be readily available, especially if the bike is older or parts are discontinued. This could require ordering from a specialized supplier or waiting for restocking.

3. **Potential for Overkill** If the bearings are only lightly worn or the failure is isolated to a specific component (e.g., seals rather than the bearings themselves), replacing the entire assembly might be unnecessary. In such cases, aftermarket bearings or refurbished parts could be a more cost-effective solution.

4. **Longer Lead Times** Depending on the supplier, ordering OEM parts may involve longer wait times compared to aftermarket options, which are often stocked by multiple vendors.

5. **No Upgrades or Performance Benefits** Unlike some aftermarket parts, these are not designed to improve performance or aesthetics. If the goal is to enhance the bike s capabilities (e.g., with lighter or high-performance bearings), OEM parts may not offer those advantages.

6. **Potential for Overmaintenance** Some riders may replace parts proactively without clear signs of wear, leading to unnecessary expenses. It s important to diagnose the issue (e.g., using a bearing tester or inspecting for play) before committing to a replacement.

### **Conclusion**

The **Honda 52100-MCA-A20 GL1800 Goldwing rear swingarm bearings** are a high-quality, reliable choice for riders who prioritize authenticity, durability, and long-term reliability. They are ideal for those who want to maintain the motorcycle s original specifications, avoid compatibility issues, and ensure seamless integration with the rest of the bike. However, the higher cost and potential overkill for minor issues make them less suitable for riders on a tight budget or those seeking performance upgrades.

For most serious Goldwing owners, especially those who value OEM components and plan to keep the bike in pristine condition, these bearings are a **strong recommendation**. If cost is a concern or the bearings are only lightly worn, exploring aftermarket options (from reputable brands like **NSK, JUN, or SKF**) or refurbished OEM parts could be a practical alternative.

If you are replacing the bearings due to noticeable wear, play, or a confirmed failure, **purchasing the genuine Honda 52100-MCA-A20 bearings is the safest and most reliable choice**. However, if the bike is otherwise in good condition and you are looking to save money, consult a mechanic to assess whether aftermarket bearings would suffice. Always prioritize quality over cost when it comes to critical components like swingarm bearings.
