### Pros and Cons of buying a Moose Offroad A28-1058 Swingarm Bearing Kit, Seal, Shaft Spacer for Yamaha XS750/XS850/XS1100
#### **Pros:**1. **Compatibility** This kit is specifically designed for Yamaha XS750, XS850, and XS1100 models, ensuring a proper fit without modification. The swingarm components are engineered to match the stock dimensions and mounting points of these bikes.
2. **Improved Durability** The bearing kit includes high-quality bearings that reduce friction and wear, extending the lifespan of the swingarm pivot. The seal prevents dirt, moisture, and debris from entering the bearing housing, reducing the risk of premature failure.
3. **Smooth Operation** A well-lubricated and properly sealed bearing assembly minimizes play and vibration in the swingarm, leading to a smoother ride and better handling. This is particularly beneficial for off-road or aggressive riding where the swingarm experiences more stress.
4. **Easy Installation** Moose Offroad kits are known for being straightforward to install, even for those with moderate mechanical experience. The kit typically includes clear instructions, and the components are designed to fit without extensive machining or customization.
5. **Cost-Effective Upgrade** Replacing worn or damaged swingarm bearings and seals is often cheaper than buying a new swingarm. This kit provides a budget-friendly way to restore or improve the performance of an existing swingarm without the full cost of a replacement.
6. **Off-Road Suitability** If you ride your XS750/XS850/XS1100 off-road or in rough conditions, this kit is particularly useful. The reinforced bearings and seals are better equipped to handle the increased stress of uneven terrain compared to stock components.
7. **Aftermarket Support** Moose Offroad is a reputable brand with a strong reputation in the off-road and custom motorcycle community. Their products are widely available through dealers and online retailers, and they often provide customer support or warranties.

#### **Cons:**1. **Potential Overkill for Light Use** If your Yamaha is primarily used for light commuting or on-pavement riding with minimal stress on the swingarm, the benefits of this kit may not be as noticeable. The cost may not be justified for low-mileage or gentle-use bikes.
2. **Installation Skill Required** While the kit is designed for ease of installation, improper handling during assembly (e.g., cross-threading, incorrect lubrication, or misalignment) can lead to premature failure or damage. Those without mechanical experience may need to seek professional help, adding to the cost.
3. **Limited Customization** This is a direct replacement kit, meaning it does not offer customization options like adjustable preload or bearing sizes. If you re looking to modify the swingarm s feel or performance beyond standard maintenance, you may need additional parts or a different solution.
4. **Compatibility with Modified Swingarms** If your swingarm has been modified (e.g., drilled for weight reduction, welded, or reinforced), the stock dimensions may no longer match. In such cases, you may need to machine or fabricate custom spacers or bearings, which could void the kit s intended use.
5. **Cost Relative to New Swingarm** While cheaper than a full swingarm replacement, the kit is still an investment. For older or high-mileage bikes where the swingarm is severely worn, the cost-benefit ratio might not justify the upgrade compared to simply replacing the swingarm entirely.
6. **Lubrication Maintenance Required** Even with a new seal and bearing, the kit will require periodic lubrication and inspection to maintain optimal performance. Neglecting maintenance could lead to premature wear despite the initial upgrade.
7. **Availability of Alternatives** Depending on your location, other brands (e.g., DID, Yoshi, or stock Yamaha parts) may offer similar kits at comparable prices. It s worth comparing options to ensure you re getting the best value for your specific needs.

### **Conclusion:**The Moose Offroad A28-1058 swingarm bearing kit, seal, and shaft spacer is a solid choice for Yamaha XS750/XS850/XS1100 owners who prioritize durability, off-road performance, or are looking to extend the life of their swingarm. It strikes a balance between cost and quality, offering noticeable improvements in smoothness and reliability without the expense of a full swingarm replacement. However, it may not be the most cost-effective solution for bikes with minimal use or those that have already undergone significant swingarm modifications.
For riders who frequently push their bikes to their limits whether on trails, in aggressive riding conditions, or after high mileage this kit is highly recommended. For casual riders or those on a tight budget, the benefits may be less pronounced, and a simpler maintenance approach (e.g., regular lubrication and inspection of stock components) could suffice.
### **Recommendation:** - **Buy the kit if:**- Your bike is used for off-road or aggressive riding.
- You notice excessive play, grinding, or wear in the swingarm bearings.
- You want to proactively extend the life of your swingarm without replacing it entirely.
- You re comfortable with basic mechanical work or have access to a mechanic for installation.
- **Avoid or reconsider if:**- Your bike is lightly used and the swingarm shows no signs of significant wear.
- You ve modified your swingarm extensively, as custom machining may be required.
- You re on a tight budget and the stock swingarm components are still in good condition.
- You prefer to wait for sales or compare alternative brands for potential cost savings.
Ultimately, this kit is a practical upgrade for those who value performance and longevity in their Yamaha s swingarm assembly. Proper installation and maintenance will ensure you get the most out of the investment.
