Review YAMAHA Rear Suspension Torque Arm Skid fits SS440 1980

The **Yamaha SS440 Rear Suspension Torque Arm (Part #8K2-47332-01-00)** is a meticulously engineered component designed to enhance the handling, stability, and overall performance of Yamaha s legendary SS440 sport-touring motorcycle, originally produced in the late 1970s and early 1980s. Crafted from high-grade steel, this torque arm serves as a critical link in the rear suspension system, transmitting the torque generated by the engine to the swingarm while absorbing road shocks and maintaining proper wheel alignment. Its robust construction ensures durability under the demands of both daily commuting and spirited riding, making it an essential part of the bike s suspension geometry. The arm s precise machining and heat-treated material resist deformation, ensuring consistent performance even after prolonged use or under heavy loads. Whether restoring an original SS440 or upgrading an existing setup, this torque arm is a direct-fit replacement, guaranteeing compatibility with the bike s stock mounting points and suspension linkages. Its inclusion in a full suspension rebuild or as a standalone repair ensures that the rear wheel remains properly aligned, reducing wear on tires, brakes, and other drivetrain components while delivering a smoother, more controlled ride. For enthusiasts seeking authenticity or those looking to restore their SS440 to factory specifications, this torque arm is a vital, no-compromise part that embodies Yamaha s attention to precision engineering from the era.

### **Pros and Cons of buying a Yamaha SS440 Rear Suspension Torque Arm (Part #8K2-47332-01-00, 1980 Model)**

1. **Direct Fitment** This part is designed specifically for the 1980 Yamaha SS440, ensuring compatibility without modification. It will drop right into place if the original torque arm is damaged or worn.

2. **Reliability** Yamaha s suspension components were built to last, and a genuine or high-quality aftermarket replacement should maintain the bike s intended handling characteristics.

3. **Performance Preservation** The torque arm plays a critical role in transferring engine torque to the rear wheel while managing suspension movement. A functioning part ensures proper weight transfer and stability, especially during acceleration and braking.

4. **Ease of Installation** The design is straightforward, requiring basic tools (socket set, torque wrench, and possibly a brake bleeder if the brake line is disconnected). Most mechanics or experienced riders can install it in under an hour.

5. **Cost-Effective Repair** Replacing a single torque arm is far cheaper than overhauling the entire rear suspension or buying a used bike with known suspension issues.

6. **Prevents Further Damage** A failing torque arm can lead to excessive play in the rear suspension, potentially damaging the swingarm, shock, or even the drive chain. Replacing it early avoids more expensive repairs.

7. **Availability of Genuine vs. Aftermarket Options** While genuine Yamaha parts may be harder to find, reputable aftermarket suppliers (like Race Tech, OEM Replacement, or eBay sellers with good reviews) offer compatible alternatives at lower prices.

---

1. **Limited Availability** Genuine Yamaha parts for older models like the SS440 can be difficult to source, especially from official dealers. Aftermarket options may require research to ensure quality.

2. **Potential for Counterfeit Parts** If purchasing from an unverified seller, there s a risk of receiving a knockoff part that doesn t meet specifications, leading to premature failure or poor performance.

3. **Rust and Wear** If the bike has been stored in harsh conditions, the torque arm or its mounting points may be corroded, requiring additional cleaning or replacement of bolts/nuts.

4. **Skill Dependency** While installation is simple, misalignment or overtightening can stress other suspension components. A rider unfamiliar with suspension work might need guidance.

5. **Cost of Additional Components** If the torque arm is part of a larger suspension failure (e.g., worn bushings, damaged swingarm), replacing just the arm may not fully resolve the issue, requiring further investment.

6. **No Performance Upgrade** This part is not an upgrade; it s a replacement for a failed component. Expect no improvements in handling or comfort just restoration of the original function.

7. **Time-Consuming if DIY** If the bike is heavily rusted or the suspension is seized, the repair may take longer than expected, especially for those without mechanical experience.

Replacing the rear suspension torque arm on a 1980 Yamaha SS440 is a **practical and cost-effective solution** if the part is failing. The benefits restoring proper suspension function, preventing further damage, and maintaining ride quality outweigh the minor drawbacks, provided you source a **genuine or high-quality aftermarket part** and perform the installation correctly. The biggest challenges are part availability and ensuring the bike s suspension is otherwise sound before replacement.

If the torque arm is the only failing suspension component and the bike is otherwise in good condition, **proceed with the repair**. If other suspension parts (e.g., swingarm bushings, shock) are also worn, consider addressing them simultaneously to avoid recurring issues.

1. **Verify the Part Number** Confirm the exact model (8K2-47332-01-00) matches your bike s torque arm. Some SS440 variants may have slight differences.

2. **Source from a Trusted Supplier** Purchase from a Yamaha dealer, a reputable aftermarket seller (e.g., Race Tech, OEM Replacement), or a verified eBay/Amazon vendor with positive reviews.

3. **Inspect the Bike s Suspension** Check for worn bushings, rusted pivot points, or a damaged swingarm before installing the new torque arm. Address any related issues to ensure longevity.

4. **Follow Installation Guidelines** Refer to a Yamaha SS440 service manual or a detailed YouTube guide (e.g., from *Motorcycle Mechanics Central* or *Bike Bandits*) for step-by-step instructions.

5. **Torque Bolts Properly** Use a torque wrench to tighten bolts to Yamaha s specified torque values to avoid stripping threads or damaging the suspension.

6. **Test Ride Carefully** After installation, take the bike for a short, controlled ride to ensure the torque arm is functioning correctly and there s no unusual play or noise.

**Final Verdict:** This is a **worthwhile repair** for restoring your SS440 s suspension to its intended condition, provided you handle the part sourcing and installation with due diligence. If the bike is a project with multiple suspension issues, prioritize addressing them in a logical order to avoid unnecessary expenses.
