Review HONDA Swingarm Bolt Axle Pivot Shaft fits XR250R XR200R 1984–1985

The **Honda 90121-KK0-000 Swingarm Bolt, Axle Pivot Shaft Assembly** is a meticulously engineered, direct-fit replacement component designed specifically for the **1984 and 1985 Honda XR250R and XR200R** off-road motorcycles. This high-quality aftermarket part is crafted to restore the original functionality and durability of the stock swingarm assembly, ensuring a secure and smooth connection between the rear wheel and the frame. The pivot shaft, a critical component of the swingarm mechanism, is precision-machined to maintain proper alignment and bearing clearance, preventing premature wear and ensuring reliable performance under rugged conditions. The accompanying swingarm bolt, often a common point of failure in these models due to stress from off-road use, is forged from high-grade steel to resist bending, stripping, or fatigue, even under heavy loads or rough terrain. This assembly is a direct replacement for the original OEM parts, featuring the same mounting dimensions and torque specifications to guarantee a perfect fit without the need for modification. Whether you're restoring a classic XR to its original glory or upgrading a well-used bike for improved reliability, this swingarm bolt and axle pivot shaft set provides the strength and precision required for off-road adventures, ensuring confidence in handling and longevity in demanding conditions.

### **Pros and Cons of buying a Honda 90121-KK0-000 Swingarm Bolt (XR250R/XR200R, 1984-1985)**

1. **Direct Fitment** This part is designed specifically for the 1984 and 1985 Honda XR250R and XR200R, ensuring compatibility without modification.

6. **Cost-Effective for Repairs** Replacing a single worn component is often cheaper than buying a full swingarm or axle assembly.

7. **Improves Safety** A secure pivot shaft and bolt assembly reduces the risk of wheel detachment or suspension failure during riding.

2. **Installation Complexity** If not experienced, removing and installing the swingarm requires careful disassembly of the rear suspension and wheel.

3. **Potential Counterfeit Parts** Some aftermarket or eBay listings may sell fake or low-quality replicas, leading to premature failure.

4. **Additional Wear Check** While replacing the bolt and pivot shaft, inspect the swingarm itself for cracks or excessive wear, which may require further repairs.

5. **Time-Consuming** The job may take several hours, depending on tool availability and mechanical skill level.

6. **Cost Variability** Prices can fluctuate based on seller, condition (new vs. used), and whether it s a genuine or aftermarket part.

7. **Compatibility Risks** If the wrong part is purchased (e.g., for a different model year), it may not fit correctly, requiring further adjustments.
