Review YAMAHA New Oem Track Drive Plate Nos

The **Yamaha 821-47591-00-00 Track Drive Plate** is a precision-engineered component designed exclusively for Yamaha s high-performance outboard motors, specifically tailored to models requiring a robust and reliable drive system. This track drive plate serves as a critical linkage between the engine s drive mechanism and the propeller shaft, ensuring seamless power transfer while maintaining optimal alignment and durability under demanding conditions. Crafted from high-grade, heat-treated steel, this component is engineered to withstand the stresses of continuous use, including exposure to saltwater corrosion, high-speed vibrations, and the relentless forces exerted during acceleration, cruising, and high-load operations. Its meticulously machined surfaces and reinforced structure minimize wear and tear, reducing the risk of premature failure and extending the operational lifespan of the outboard motor. The design incorporates precise tolerances to guarantee a snug fit within the engine s drive assembly, preventing excessive play that could lead to misalignment or damage to adjacent components. Whether installed on a recreational fishing boat, a high-speed cruiser, or a performance-oriented vessel, this track drive plate delivers uncompromising reliability, making it an indispensable part of Yamaha s reputation for engineering excellence in marine propulsion systems.

### Yamaha Track Drive Plate (Part Number: 821-47591-00-00) Pros and Cons

#### **Pros**

1. **Compatibility and Fitment** This part is designed specifically for Yamaha track drive systems, ensuring a precise fit with minimal modifications required. It is commonly used in models like the Yamaha YZF-R1, R6, and other sportbikes with similar drivetrains, reducing the risk of installation issues.

2. **Durability and Quality** Yamaha is known for producing high-quality components, and this track drive plate is no exception. It is typically made from strong, heat-treated materials to withstand the stresses of high-performance riding, including aggressive acceleration and braking.

3. **Aftermarket Support** Since this part is widely used, it has a strong aftermarket presence. You can easily find replacement parts, gaskets, or related components if needed. Additionally, many mechanics and tuners are familiar with it, making maintenance and upgrades straightforward.

4. **Performance Potential** A well-maintained track drive plate contributes to smoother power delivery and reduced wear on the clutch and transmission. If you plan to modify your bike for track use, this part is a solid foundation for further upgrades like clutch kits or flywheel balancing.

5. **Cost-Effective for Replacement** Compared to full drivetrain replacements, this plate is relatively inexpensive. If your original plate is worn or damaged, replacing just this component can restore functionality without a full rebuild.

6. **Ease of Installation** For those with basic mechanical skills, replacing the track drive plate is a manageable DIY job. It typically requires removing the clutch, flywheel, and other related components, but Yamaha s design simplifies the process compared to some competitors.

7. **Track-Specific Design** The part is often optimized for track use, meaning it may handle higher RPMs and loads better than a standard street plate, which can be beneficial for racers or enthusiasts pushing their bikes hard.

#### **Cons**

1. **Wear and Tear Over Time** Like any mechanical component, this plate will wear out, especially under heavy use. If not properly maintained (e.g., regular clutch adjustments, proper lubrication), it can lead to slipping, grinding, or premature failure.

2. **Limited Longevity Without Upgrades** For aggressive track use or high-performance modifications (e.g., big-bore kits, aggressive clutch setups), the stock plate may not last as long as aftermarket alternatives designed for extreme conditions. Upgrading to a reinforced or track-specific plate (e.g., from brands like Didi, K-Tech, or Yamaha s own track parts) may be necessary for longevity.

3. **Potential for Misalignment** If not installed correctly, the plate can become misaligned with the flywheel or clutch, leading to uneven wear, clutch drag, or even damage to the transmission. Precision is key during installation.

4. **Cost of Related Components** While the plate itself is affordable, replacing it may require purchasing additional parts like a new clutch, gaskets, or even a flywheel if they are worn. These add to the overall cost and time investment.

5. **Availability Concerns** While widely available, there is always a risk of stock shortages, especially if you re buying from a third-party seller. Always verify the seller s reputation and check for authenticity to avoid counterfeit parts.

6. **Skill Dependency** Replacing the plate requires familiarity with motorcycle drivetrain mechanics. Mistakes during installation (e.g., improper torque, incorrect alignment) can lead to costly repairs or performance issues.

7. **Not a Permanent Solution for All Issues** If your bike has other drivetrain problems (e.g., worn synchronizers, transmission issues), replacing just the track drive plate won t fix those. A full drivetrain inspection may be needed for optimal performance.

### **Conclusion**

The Yamaha track drive plate (821-47591-00-00) is a reliable and cost-effective component for maintaining or upgrading your Yamaha bike s drivetrain, particularly for track use. Its compatibility, durability, and ease of installation make it a practical choice for both DIY enthusiasts and professional mechanics. However, it is not a "forever" part it will wear out over time, especially under heavy loads, and may require complementary upgrades (like a clutch kit or flywheel balancing) for optimal performance in aggressive riding scenarios.

If you re replacing a worn plate or preparing your bike for track days, this part is a solid starting point. For extreme track use or high-performance builds, consider pairing it with aftermarket upgrades designed for higher stress. Always ensure proper installation and maintenance to maximize its lifespan.

---

### **Recommendation**

- **Buy it if:** You need a direct replacement for a worn plate, your bike is stock or lightly modified, and you re comfortable with basic drivetrain maintenance. It s also a good choice if you want a cost-effective way to restore smooth power delivery.

- **Consider alternatives if:** You re building a high-performance track bike, as aftermarket plates (e.g., from Didi or K-Tech) may offer better durability and performance under extreme conditions. Also, pair it with a clutch upgrade if you plan to push the bike hard.

- **Where to buy:** Purchase from reputable Yamaha dealers, trusted aftermarket suppliers (e.g., Raceface, Didi, or local bike shops with good reviews), or verified online marketplaces to avoid counterfeit parts.

- **Installation tip:** If you re not experienced with motorcycle drivetrains, have a mechanic perform the installation to ensure proper alignment and torque specifications are met.

Overall, this part is a practical and widely recommended choice for Yamaha owners, but always weigh its pros and cons against your specific riding needs and budget.
