( Manufacturer Part Number: 52170-KRN-710 ), ( Type: Chain Slider )

Review HONDA Oem Chain Support Guide Thrust fits SLIDER CRF450R 2005–2008

The **Honda 52170-KRN-710 05-08 CRF450R Chain Thrust Slider (Part #B4529)** is a precision-engineered component designed specifically for Honda s CRF450R models produced between 2005 and 2008, ensuring optimal performance and longevity for the bike s drivetrain. This chain thrust slider, also known as a chain tensioner or guide slider, plays a critical role in maintaining proper chain alignment and reducing wear on the sprocket and chain by absorbing lateral forces generated during high-speed riding, aggressive cornering, or off-road conditions. Crafted from high-quality, durable materials, this slider features a robust construction that resists deformation under stress, helping to minimize chain stretch and prevent premature failure of the drivetrain components. Its design incorporates a smooth, low-friction surface that reduces chain noise and vibration, contributing to a quieter and more efficient ride. The slider s precise fit within the CRF450R s chain tensioner assembly ensures consistent tension, which is vital for optimal power transfer, fuel efficiency, and overall handling. Whether you're tackling rough trails, pushing the limits on the track, or cruising through varied terrain, this slider helps maintain the integrity of the chain and sprocket, extending the life of your bike s drivetrain and reducing the need for frequent adjustments or replacements. Ideal for both stock and modified CRF450R setups, this part is a straightforward yet essential upgrade for riders who demand reliability and performance from their motorcycle.

The Honda CRF450R (2005-2008) with the **chain thrust slider (part #B4529)** and **52170-KRN-710** chain is a popular bike among off-road enthusiasts, but it has both advantages and drawbacks depending on your needs, budget, and experience level.

### **Pros of Buying This Bike**

1. **Proven Reliability and Durability**

The CRF450R from this era is well-regarded for its robust engine, strong frame, and dependable components. Honda s reputation for longevity means many of these bikes last well beyond 10,000 miles with proper maintenance.

2. **Off-Road Capability**

The CRF450R is designed for trail riding, with a lightweight aluminum frame, aggressive suspension tuning, and a powerful yet efficient 449cc parallel-twin engine. It handles rough terrain better than many dual-sport bikes and is lighter than full-on enduro bikes.

3. **Aftermarket Support**

The CRF450R has a strong aftermarket presence, with readily available parts (suspension, exhaust, clutch, etc.), performance upgrades, and tuning options. This makes it easier to customize for your riding style.

4. **Fuel Injection (FI) Over Carburetion**

Unlike earlier CRF models, the 2005-2008 versions use fuel injection, which improves throttle response, fuel efficiency, and reliability compared to carbureted bikes.

5. **Resale Value**

While not as high as newer models, the CRF450R retains decent resale value due to its reputation for being a capable trail bike.

6. **Chain Thrust Slider (B4529) and Chain (52170-KRN-710) Compatibility**

The chain thrust slider is a common upgrade for reducing chain wear and improving drivetrain longevity. The **52170-KRN-710** is a high-quality, durable chain (likely a KMC or similar brand) that works well with the slider, reducing chain stretch and improving performance.

7. **Lower Cost of Ownership (Compared to New Bikes)**

The bike is significantly cheaper than a new model, making it an attractive option for riders who want a capable off-road bike without breaking the bank.

### **Cons of Buying This Bike**

1. **Age and Wear**

Being from 2005-2008, the bike has been on the market for nearly 20 years. Key components like the suspension, tires, and drivetrain may be worn out, requiring immediate replacement. A thorough inspection is essential before purchase.

2. **Maintenance Requirements**

Older bikes often need more frequent maintenance than newer models. The fuel injection system, while better than carburetors, can still develop issues over time, and components like the clutch and chain may wear faster if not properly cared for.

3. **Suspension Limitations**

The stock suspension on the CRF450R is tuned for aggressive trail riding but may feel stiff or inadequate for heavy-duty enduro or long-distance riding. Upgrading to aftermarket suspension (e.g., hlins, YSS, or Fox) can be costly.

4. **Fuel Injection Tuning Challenges**

While FI is an improvement over carburetors, tuning the ECU for performance can be tricky without a tuner or aftermarket solution. Some riders may need to invest in a device like a Power Commander or Motec to optimize power and throttle response.

5. **Potential for Rust and Corrosion**

If the bike has been stored improperly (e.g., in wet conditions), rust can develop on critical parts like the frame, swingarm, and suspension. A pre-purchase inspection is crucial to avoid hidden damage.

6. **Tire Wear**

Trail tires (like Michelin Wild Rider or Maxxis Minion) wear out quickly on rough terrain. Replacing tires can be expensive, especially if the bike is used for heavy-duty riding.

7. **Limited Modern Safety Features**

Compared to newer bikes, the CRF450R lacks advanced electronics (e.g., traction control, ABS, or advanced suspension damping maps). While this isn t a dealbreaker for many riders, it may be a consideration for those prioritizing modern tech.

8. **Parts Availability**

While parts are still widely available, some specialized components (e.g., rare suspension seals or specific aftermarket parts) may become harder to find over time.

### **Conclusion**

- Are an experienced rider looking for a capable, reliable off-road bike.

- Want a bike with strong aftermarket support and customization options.

- Are willing to invest in maintenance and potential upgrades (suspension, tires, etc.).

- Prefer a proven, durable platform over a newer but potentially more expensive bike.

- Are a beginner who needs a more forgiving, modern bike with advanced safety features.

- Plan to ride heavily in rough conditions without upgrading key components.

- Want a bike that requires minimal maintenance or has the latest technology.

### **Recommendation**

- **Pre-purchase inspection** (check for rust, suspension leaks, clutch wear, and engine condition).

- **Budgeting for upgrades** (tires, suspension, chain, and possibly a clutch if worn).

- **Investing in a tuner** if you want to optimize performance.

For a **first-time buyer or someone seeking a more modern experience**, consider newer models like the **2020 CRF450R** or other brands with advanced features. But for **enthusiasts who value durability, aftermarket support, and off-road capability**, this bike remains a strong choice.
