Review HONDA Judder Spring Seat fits TRX450ER TRX ER 450 2006

The **Honda 22125-MBN-670 2006 TRX450ER** is a meticulously crafted aftermarket replacement part designed to elevate the comfort, performance, and durability of Honda s legendary **TRX450ER**, the iconic off-road ATV known for its rugged reliability and trail-conquering prowess. This **670mm (26.4-inch) suspension seat** is engineered to replace the stock seat, offering a blend of ergonomic support and off-road resilience that caters to both casual riders and seasoned trail enthusiasts. Crafted from high-quality, durable materials, the seat features a **reinforced frame** with strategic padding distribution to minimize fatigue during extended rides, ensuring that the rider remains stable and comfortable even during high-speed descents or prolonged off-road excursions. The **judder spring** integrated into the design is a standout feature, providing a subtle yet effective damping mechanism that reduces vibrations transmitted from the suspension to the seat, thereby enhancing rider control and reducing wear on the spine over time. This spring system is particularly beneficial for riders tackling rough terrain, as it helps smooth out the jolts and impacts that can otherwise lead to discomfort or long-term strain. The seat s **universal fitment** is tailored specifically for the 2006 TRX450ER, ensuring a seamless installation with minimal modifications required, while its **water-resistant upholstery** guarantees longevity even in wet or muddy conditions. Whether you're navigating rocky trails, dense forests, or rocky deserts, this seat delivers a harmonious balance of support, durability, and ride quality, making it an essential upgrade for any TRX450ER owner seeking to enhance their off-road experience without compromising on performance.

### **Pros and Cons of Buying a 2006 Honda TRX450ER (Model 22125-MBN-670) with a Juddering Spring and Seat**

#### **Pros**

1. **Reliable Honda Engine** The TRX450ER is powered by Honda s proven 450cc parallel-twin engine, known for durability and consistent performance. With proper maintenance, this engine can easily last well over 10,000 hours.

2. **Off-Road Capability** The TRX450ER is designed for rugged terrain, featuring a robust frame, long-travel suspension, and a low gearing ratio. It performs well in sand, mud, and rocky trails, making it a solid choice for serious off-road enthusiasts.

3. **Proven Suspension System** The stock suspension (including the rear shock) is robust and adjustable, allowing for customization to suit different riding conditions. While the spring may be worn, Honda s suspension components are generally reliable if maintained.

4. **Resale Value** Honda s reputation for longevity means the TRX450ER retains decent resale value compared to some competitors, especially if it has a clean service history.

5. **Ease of Maintenance** Honda s design makes it relatively straightforward to perform basic maintenance, such as oil changes, air filter replacements, and chain adjustments. Parts are widely available, and mechanics familiar with Honda ATVs are common.

6. **Comfortable for Its Class** Despite the seat and spring issues, the TRX450ER is still more comfortable than many bare-bones off-road ATVs. The stock seat, while worn, provides adequate support for shorter rides.

7. **Versatility** The TRX450ER can handle a variety of tasks, from trail riding to light utility work, making it a practical choice for those who need a multi-purpose ATV.

#### **Cons**

1. **Worn Spring and Juddering Suspension** The most immediate concern is the rear spring, which may be stretched or broken, causing a juddering or bouncing effect. This can lead to an uncomfortable ride and potentially damage the shock absorber over time. Replacing the spring and shock is a necessary repair before serious use.

2. **Worn Seat** The seat is likely cracked, sagging, or otherwise damaged, reducing comfort and potentially posing a safety risk. A replacement seat is a reasonable first upgrade.

3. **Age and Mileage** A 2006 model is now over 15 years old, meaning it has likely accumulated significant mileage. Without a detailed service history, there could be hidden issues such as worn bearings, clutch problems, or transmission wear.

4. **Potential Electrical Issues** Older Honda ATVs can develop electrical gremlins, such as faulty wiring, failing lights, or intermittent starter problems. Testing the electrical system thoroughly is essential.

5. **Rust and Wear** If the ATV has been stored improperly or ridden in harsh conditions, rust on the frame, undercarriage, or suspension components could be an issue. A thorough inspection is critical.

6. **Stock Suspension Limitations** While adjustable, the stock suspension may not be sufficient for extreme off-road use without upgrades. The TRX450ER benefits from aftermarket suspension components for better performance.

7. **Fuel System Concerns** Older ATVs can develop carburetor or fuel injection issues. If the model has a carburetor (some early TRX450ERs did), it may require cleaning or replacement. Fuel injection models are more reliable but can still develop problems over time.

8. **Tires and Brakes** The stock tires may be worn, and the brakes (especially the rear) could be less effective. Replacing tires and brake pads is a common first-step repair.

### **Conclusion**

The 2006 Honda TRX450ER is a capable and durable off-road ATV, but its age and the specific issues with the spring and seat mean it requires attention before it can be safely and comfortably ridden. If you are prepared to invest in necessary repairs such as replacing the rear spring, shock, and seat this ATV could be a solid purchase for someone who values reliability and off-road performance. However, if you are looking for a turnkey machine with minimal upfront costs, you may want to consider a newer model or a well-maintained used example with a clean history.

### **Recommendation**

- **Buy if:** You are mechanically inclined, have a budget for repairs, and are willing to invest in upgrades (suspension, seat, tires, etc.). The TRX450ER is a great platform for customization, and with proper maintenance, it can provide years of reliable service.

- **Avoid if:** You want a low-maintenance ATV with no immediate repair costs. In that case, consider a newer model or a different brand with a better warranty or service record.

- Inspect the suspension thoroughly (check for spring damage, shock leaks, and proper function).

- Test the seat for structural integrity and comfort.

- Review the service history for maintenance records.

- Have a mechanic perform a pre-purchase inspection to identify any hidden issues.

- Budget for at least $500 $1,000 in repairs and upgrades before regular use.

Ultimately, the TRX450ER is a strong choice for the right buyer one who appreciates Honda s engineering and is willing to put in the work to keep it running smoothly.
