Review KTM Skid Plate 450/500 Sx/xc/exc 7940399000 fits SX XC 450 500

The **KTM 79403990000 Skid Plate** is a meticulously engineered aftermarket undercarriage protection designed specifically for the 450/500 cc KTM 500 SX-F, 500 XC-W, and 500 EXC-F models, ensuring optimal durability and performance while safeguarding your bike s critical components from the rigors of off-road and aggressive riding. Crafted from high-grade, impact-resistant polycarbonate, this skid plate is built to withstand the harshest terrain, including rocky trails, muddy tracks, and rough descents, where even the most minor debris or uneven surfaces can pose a threat to your bike s underbelly. Its precision-fit design ensures seamless integration with the stock frame, eliminating gaps that could allow dirt, water, or sharp objects to compromise your bike s suspension, exhaust, or fuel system. The reinforced structure of the skid plate is strategically contoured to match the contours of your KTM s undercarriage, providing comprehensive coverage from the swingarm to the rear fender, while also protecting the engine case, transmission, and other vulnerable areas from scrapes, dents, and potential damage during high-speed jumps or aggressive cornering. Beyond its protective function, this skid plate is engineered for practicality, featuring a lightweight yet robust construction that minimizes unnecessary weight transfer, allowing your bike to maintain its agile handling and responsiveness. Additionally, the material s resistance to corrosion and wear ensures long-term reliability, even in the most demanding conditions, making it an indispensable upgrade for riders who demand both performance and protection. Whether you re tackling competitive enduro races, exploring remote backcountry trails, or simply pushing your bike s limits in daily riding, this skid plate serves as a bulletproof shield, allowing you to focus on the ride without worrying about the unseen threats lurking beneath your wheels.

### **Pros and Cons of buying a KTM 79403990000 Skid Plate (Fits 450/500 SX/XC/EXC)**

1. **Durability and Protection** The skid plate is designed to shield the engine, transmission, and undercarriage from rocks, debris, and impacts during off-road riding. This helps prevent costly damage to critical components.

2. **Universal Fit** This specific part (79403990000) is engineered to fit multiple KTM models, including the **450/500 SX, XC, and EXC**, making it a versatile aftermarket or replacement option if you own or plan to own one of these bikes.

3. **Lightweight Construction** KTM s skid plates are typically made from high-strength aluminum or composite materials, which balance protection with minimal weight impact on handling.

4. **Easy Installation** Most KTM skid plates are designed for straightforward bolt-on installation, requiring basic tools and minimal mechanical skill. Some may include mounting hardware or clear instructions.

5. **Enhanced Longevity** By preventing scratches, dents, and potential engine damage from rough terrain, the skid plate extends the life of your bike s undercarriage and internal components.

6. **Aesthetic Consistency** If you re replacing a damaged or worn-out stock plate, this aftermarket option often matches the factory design, maintaining the bike s appearance while improving functionality.

7. **Cost-Effective Compared to Repairs** Replacing a damaged skid plate is far cheaper than repairing engine or transmission damage caused by debris strikes. It s a preventive maintenance measure that pays off in the long run.

---

1. **Potential for Loose Mounting** Some aftermarket skid plates, especially cheaper or poorly fitted ones, may not secure as tightly as OEM parts. This could lead to rattling or detachment during aggressive riding, posing a safety risk.

2. **Limited Customization** Unlike some aftermarket options, this specific KTM part is likely a standard fit rather than a customizable or reinforced version. If you need additional protection (e.g., for extreme racing), you may need to source a heavier-duty plate.

3. **Compatibility Verification Required** While it s advertised for multiple models, double-checking that the **79403990000** part number is an exact fit for your specific bike (e.g., year and variant) is crucial. Some minor model-specific differences (e.g., exhaust or frame modifications) could affect installation.

4. **Quality Variability** If purchasing from a third-party seller (e.g., eBay, Amazon, or a non-KTM authorized dealer), there s a risk of receiving a counterfeit or lower-quality duplicate. Always buy from reputable sources like KTM dealers or trusted aftermarket suppliers.

5. **Weight Addition** While KTM s plates are lightweight, any additional undercarriage protection will slightly increase the bike s weight, which may marginally affect acceleration and handling, especially on lighter riders.

6. **Potential for Scratches or Wear** Even with a skid plate, the edges of the plate itself can scratch the bike s paint if not installed carefully or if debris gets trapped between the plate and the frame.

7. **Replacement Cost** If the plate is damaged in a crash or from heavy use, replacing it can be an additional expense. However, this is a trade-off for the protection it provides.

---

The **KTM 79403990000 skid plate** is a practical and reliable choice for protecting your **450/500 SX/XC/EXC** from off-road damage. Its universal fit, durability, and ease of installation make it a worthwhile investment for riders who prioritize preventive maintenance. However, ensure you purchase from a trusted source to avoid counterfeit parts, verify compatibility with your exact bike model, and consider the minor trade-offs like weight and potential loose mounting if not installed correctly.

- **Buy from an authorized KTM dealer or a reputable aftermarket supplier** to guarantee authenticity and quality.

- **Check the part number against your bike s specifications** to confirm it s the correct fit.

- **Install it properly** using the included hardware or OEM fasteners to prevent rattling or detachment.

- **Consider additional protection** (e.g., a reinforced skid plate or underframe guards) if you ride in extremely rough or competitive conditions.

- **Inspect the plate regularly** for cracks, loose bolts, or signs of wear to ensure ongoing protection.

Overall, this skid plate is a **strong, cost-effective solution** for riders who want to safeguard their bike s undercarriage without compromising performance.
