Review TRIUMPH BSA Cluth Fiber Plates Good Used fits TWIN

The Triumph BSA 57-1363 and 57-1362 fiber clutch plates represent a meticulously engineered pair of aftermarket components designed to enhance the performance, durability, and reliability of classic Triumph and BSA twin-cylinder motorcycles. These clutch plates are crafted from high-quality fiber materials, offering an ideal balance between smooth engagement, responsive power delivery, and long-lasting wear resistance. The 57-1363 model is the primary drive plate, featuring a robust, multi-layered construction that ensures progressive clutch action, reducing the likelihood of abrupt power surges and providing a more refined riding experience. Its precise alignment with the pressure plate and flywheel allows for optimal torque transfer, making it an excellent choice for both street and light track use. Complementing the primary plate is the 57-1362 secondary plate, which serves as the reverse plate, ensuring a consistent and even distribution of friction across the clutch assembly. Together, these plates are engineered to withstand the demands of high-revving engines while maintaining a silky-smooth engagement, ideal for riders seeking to preserve the original character of their classic machines without compromising on performance. Whether restoring a vintage Triumph or BSA model or upgrading an existing setup, these clutch plates deliver a seamless blend of heritage craftsmanship and modern reliability, making them a trusted choice for enthusiasts who demand both authenticity and performance.

The Triumph BSA 57-1363 and 57-1362 clutch components (twin clutch plates and fiber plates) are aftermarket parts designed to replace the stock clutch in older Triumph and BSA motorcycles, particularly those from the 1950s to 1970s. Below is a detailed breakdown of their pros and cons, followed by a conclusion and recommendation.

### **Pros of Buying Triumph BSA 57-1363 (Twin Clutch Plates) and 57-1362 (Fiber Plates)**

1. **Improved Durability and Performance**

The aftermarket clutch plates are often made from higher-quality materials than the original components, which can degrade over time due to heat, friction, and wear. The 57-1363 twin plates and 57-1362 fiber plates are designed to handle increased torque and provide smoother engagement, reducing wear on the presser foot and flywheel. This can extend the lifespan of the entire clutch assembly.

2. **Better Heat Resistance**

Fiber clutch plates (like the 57-1362) are engineered to withstand higher temperatures better than traditional leather or asbestos-based plates. This reduces the risk of clutch fade, especially in stop-and-go traffic or under heavy load, which is common in classic motorcycles with manual transmissions.

3. **Smoother Engagement and Reduced Clutch Drag**

Many riders report that these aftermarket plates provide a more progressive engagement, reducing the "judder" or harshness often associated with older clutches. The fiber plates (57-1362) in particular are known for their ability to reduce clutch drag, which can improve fuel efficiency and reduce wear on the transmission.

4. **Compatibility with Modern Modifications**

If you ve upgraded your bike with a heavier flywheel, larger sprocket, or increased engine modifications, the stock clutch may struggle to handle the additional torque. The 57-1363 and 57-1362 plates are designed to work with these modifications, providing the necessary grip and durability.

5. **Easier Installation and Maintenance**

These parts are often designed to fit standard BSA/Triumph clutch systems with minimal modification. They come pre-drilled and pre-punched, making installation straightforward for those with basic mechanical skills. Additionally, they are easier to service and replace compared to original plates that may have deteriorated or warped.

6. **Reliability for Classic Motorcycles**

Classic motorcycles are often ridden less frequently but with more intensity when they are used. The 57-1363 and 57-1362 plates are built to handle occasional heavy use without failing, making them a practical choice for enthusiasts who want to preserve their bike s originality while improving functionality.

7. **Cost-Effective Upgrade**

Compared to a full clutch overhaul or replacement, these plates are relatively inexpensive. They offer a significant improvement in performance without requiring major modifications to the bike.

### **Cons of Buying Triumph BSA 57-1363 and 57-1362 Clutch Plates**

1. **Potential for Incompatibility with Stock Clutch Systems**

While these plates are designed for BSA/Triumph clutches, there is a risk of fitment issues if the flywheel or presser foot has been heavily modified or worn. For example, if the flywheel springs are weak or the presser foot is bent, the new plates may not engage properly, leading to slipping or uneven wear. Always inspect the clutch components before installation.

2. **Requires Proper Installation and Adjustment**

If the clutch is not adjusted correctly after installation, the plates may not engage smoothly, leading to premature wear or failure. Improper installation can also cause the clutch to drag, leading to increased heat and reduced fuel efficiency. This requires some mechanical knowledge or the assistance of a professional.

3. **Limited Availability of Parts and Expertise**

Classic motorcycle parts, especially aftermarket clutch components, can be harder to find than modern parts. If you encounter issues with the 57-1363 or 57-1362 plates, sourcing replacements or finding a specialist to diagnose the problem may be challenging. This is particularly true for older models where expertise is less common.

4. **Possible Adaptation Period**

Some riders report that aftermarket clutch plates, especially fiber plates, may require a brief adaptation period. The clutch may feel slightly different in terms of engagement point or smoothness, which can take a few rides to adjust to. This is generally minor but worth considering if you prioritize immediate familiarity.

5. **Cost of Additional Components**

While the plates themselves are affordable, you may need to purchase additional components such as a new throw-out bearing, clutch springs, or a flywheel if they are worn. These extras can add to the overall cost, though they are often necessary for a complete clutch upgrade.

6. **Potential for Overkill on Low-Mileage Bikes**

If your motorcycle is rarely ridden or has a stock clutch that is still in good condition, upgrading to these plates may not be immediately necessary. For bikes that are primarily used for occasional rides, the stock clutch might suffice, and the upgrade could be deferred until symptoms of wear (e.g., slipping, juddering) appear.

7. **Environmental Concerns with Fiber Plates**

While fiber clutch plates are more durable and heat-resistant than traditional asbestos plates, they are not entirely environmentally friendly. However, modern fiber plates are generally safer than asbestos-based alternatives, and the environmental impact is minimal compared to the benefits they provide.

### **Conclusion**

The Triumph BSA 57-1363 twin clutch plates and 57-1362 fiber plates are a practical and effective upgrade for classic BSA/Triumph motorcycles, particularly those with stock clutches showing signs of wear or those that have been modified to handle increased torque. They offer improved durability, smoother engagement, and better heat resistance, making them ideal for riders who want to enhance performance without a full clutch rebuild. However, they are not a universal fix and require proper installation, adjustment, and sometimes additional components to function optimally.

For riders who prioritize reliability, performance, and longevity especially those who modify their bikes or ride them frequently the 57-1363 and 57-1362 plates are a strong recommendation. For those with low-mileage bikes or stock clutches in good condition, the upgrade may not be urgent, but it is a wise long-term investment to prevent future issues.

### **Recommendation**

If you are experiencing clutch slipping, juddering, or drag in your BSA/Triumph motorcycle, or if you ve made modifications that increase torque, I recommend installing the Triumph BSA 57-1363 twin clutch plates and 57-1362 fiber plates. Pair this upgrade with a new throw-out bearing and inspect the flywheel and presser foot for wear. If you are not comfortable with clutch installation, consult a professional mechanic experienced with classic motorcycles to ensure proper fitment and adjustment.

For riders who are unsure whether their clutch needs upgrading, monitor its performance over time. If symptoms persist or worsen, the plates are a cost-effective solution to restore smooth operation and extend the life of your motorcycle s drivetrain. Ultimately, this upgrade strikes a balance between performance enhancement and practicality for classic motorcycle enthusiasts.
