### **Pros and Cons of buying a Yamaha Pivot Shaft (Part Number: 802-47337-00-00, GP29273-74, SL338 for 72-74 GP Models)**
#### **Pros:**1. **OEM Quality and Compatibility** This is an original Yamaha part designed specifically for the 1972-1974 GP (Gavilan) and SL (Scrambler) models. It ensures a perfect fit without modification, reducing the risk of installation issues.
2. **Durability and Performance** Yamaha parts are known for their reliability and longevity, especially in critical components like the pivot shaft, which supports the swingarm and affects handling. A high-quality shaft reduces wear on suspension components and improves stability.
3. **Easier Maintenance** Since it s a genuine part, it s built to Yamaha s standards, meaning it should last as long as the original (or longer) without premature failure. This reduces the need for frequent replacements or adjustments.
4. **Resale Value** If you plan to sell the bike later, having OEM parts can make it more appealing to buyers who prefer complete or restored models.
5. **Warranty Coverage** If purchased from an authorized Yamaha dealer or a reputable seller, it may come with a warranty, providing peace of mind against defects.
6. **Avoids Counterfeit Risks** Non-OEM parts, even if labeled as "Yamaha," can be knockoffs with inferior materials or poor machining. This part guarantees authenticity.
7. **Supports the Bike s Original Intent** Using OEM parts preserves the bike s original specifications, which can be important for enthusiasts who prioritize authenticity in restorations.

#### **Cons:**1. **Higher Cost** Original Yamaha parts are significantly more expensive than aftermarket alternatives. For a pivot shaft, this could be 2-3 times the price of a generic or third-party replacement.
2. **Limited Availability** Since these models are older, finding the exact part may require ordering from a specialty motorcycle parts distributor or an online marketplace (eBay, Yamaha s official site, or used marketplaces). Lead times can be longer than for newer bikes.
3. **Potential for Overkill** If the pivot shaft is only slightly worn or the bike is used for light riding, replacing it with a new OEM part may be unnecessary. In such cases, a refurbished or aftermarket part could suffice.
4. **Installation Complexity** Replacing a pivot shaft often requires removing the swingarm, which is a moderately advanced task. If you re not experienced with motorcycle mechanics, you may need to pay for professional installation, adding to the cost.
5. **Weight Consideration** Original Yamaha parts are often heavier than modern or aftermarket alternatives. While this isn t a major issue for most riders, it may slightly affect handling or fuel efficiency on older bikes.
6. **Environmental and Ethical Concerns** If you re concerned about sustainability, purchasing a new OEM part contributes to e-waste and resource consumption. Refurbished or used parts could be a more eco-friendly option.
