Review RACE DRIVEN Kawasaki Front And Rear Brake Pads Mudrat fits KLX400S KLX400 2003–2004

The **Race-Driven S-31532 2003-2004 Kawasaki KLX400S/KLX400 Front & Rear Brake Pads** are a high-performance, off-road-specific upgrade designed to deliver superior stopping power, durability, and reliability for aggressive trail riding, racing, and heavy-duty use. Engineered with **MudRAT s signature blend of advanced friction materials**, these brake pads are meticulously formulated to withstand the extreme demands of off-road environments, including deep mud, loose rocks, and high-speed descents where traditional brake components often fail. The **S-31532 compound** strikes an optimal balance between heat resistance, bite, and longevity, ensuring consistent performance even under prolonged braking or in high-temperature conditions. Unlike stock pads, which may wear unevenly or lose effectiveness when saturated with mud or debris, these pads feature a **reinforced backing plate** and **optimized friction surface** that resists clogging, reducing the risk of brake fade and improving overall responsiveness. Perfectly compatible with the **2003 and 2004 Kawasaki KLX400S and KLX400**, these pads are a direct-fit replacement, eliminating the need for modification and ensuring a seamless installation. Whether you're tackling technical trails, competing in enduro races, or pushing your bike to its limits in rugged terrain, these **Race-Driven MudRAT brake pads** provide the confidence-inspiring stopping power and durability required to keep you in control no matter how harsh the conditions. Built to endure the rigors of off-road riding, they offer a noticeable improvement in braking efficiency, reducing pedal travel and enhancing modulation for precise control, making them an essential upgrade for serious riders who demand the best from their equipment.

### **Pros and Cons of Buying a Used 2003 2004 Kawasaki KLX-400S (Race-Driven, S-31532, Front/Rear Brake Pads, Mud Rat)**

#### **Pros**

1. **Strong Off-Road Performance** The KLX-400S is a reliable and capable dual-sport/motocross bike, known for its lightweight frame, efficient 399cc single-cylinder engine, and balanced handling. It s well-suited for trail riding, light motocross, and enduro.

2. **Proven Reliability** Kawasaki s 399cc single-cylinder engine in this era is durable and straightforward, with fewer complex components compared to modern multi-cylinder bikes. Many KLX-400S models from this period have lasted well with proper maintenance.

3. **Affordable Entry Point** Used KLX-400S models from 2003 2004 are significantly cheaper than newer dual-sport or motocross bikes, making them an attractive option for riders on a budget.

4. **Modularity and Upgrade Potential** The KLX-400S platform is well-supported by aftermarket parts. You can upgrade suspension (e.g., hlins, YSS), exhaust (e.g., Akrapovic, K&N), and components (e.g., clutch, chain, tires) to improve performance.

5. **Lightweight and Maneuverable** Weighing around 220 240 lbs (dry), it s easier to handle than larger dual-sports or adventure bikes, making it ideal for technical trails or tight spaces.

6. **Fuel Efficiency** The single-cylinder engine is thirsty but not excessive, offering decent range for trail riding (about 30 40 miles per tank).

7. **Community and Support** The KLX-400S has a dedicated following, with forums (e.g., KLX-400S.com, Motocross Action), parts availability, and DIY maintenance guides widely available.

8. **Race-Driven Modifications** If the bike has been race-prepped (e.g., lowered suspension, stiffer fork springs, upgraded clutch, or brake pads), it may already have performance enhancements that justify the purchase.

9. **Mud Rat (Mud-Terrain) Suitability** The KLX-400S is often used in muddy conditions, and the stock suspension can be adjusted or upgraded for better mud clearance and traction.

10. **Simplicity for Beginners** The bike s straightforward design makes it easier to learn on compared to more complex modern bikes, and repairs are often DIY-friendly.

#### **Cons**

- **Poor ergonomics** The stock seat and handlebar position can be uncomfortable for taller riders or those with back issues.

- **Basic suspension** Stock shocks and forks are stiff and lack adjustability compared to modern units. Upgrades are often necessary for serious riding.

- **Weak brakes** The stock front and rear brakes (especially the rear) are underpowered for aggressive riding. Upgrading to disc brakes (e.g., Brembo, Magura) or larger pads (as mentioned in your note) is recommended.

- **Peak power is modest** ( 30 35 hp), which may feel slow on highways or against strong headwinds.

- **Torque is adequate but not overwhelming**, making it suitable for trails but not for aggressive cornering or high-speed riding.

- **No electronic aids** (e.g., traction control, launch control, or slipper clutches) that modern bikes offer.

- **Chain and sprocket wear** Single-cylinder bikes are prone to chain stretch and sprocket wear, requiring frequent checks and replacements.

- **Carburetion sensitivity** The stock carburetor (e.g., Keihin) can be finicky and may require tuning for optimal performance, especially after modifications.

- **Rust and corrosion** If the bike has been stored improperly or ridden in wet conditions, rust can be an issue, particularly on the frame and suspension components.

4. **Resale Value** The KLX-400S is not a high-demand bike in the used market, so resale value is low compared to more popular models like the CRF450RX or RM-Z450.

5. **Stock Suspension Limitations** The stock suspension is not adjustable and can feel harsh or too stiff for some riders. Upgrading to adjustable units (e.g., hlins, YSS) is often necessary for comfort and performance.

6. **Tire Wear** The stock tires (e.g., Michelin Wild Rider or Bridgestone M480) are durable but not as grippy as modern off-road tires. Upgrading to knobby tires (e.g., Maxxis Minion DHF, Pirelli Scorpion Trail) can improve traction.

- **No ABS** (though not critical for off-road).

- **No digital instrumentation** (stock models have basic analog gauges).

- **No modern suspension damping** (e.g., compression/rebound adjustability).

- **Worn-out suspension seals** leading to oil leaks.

- **Cracked or rusted frame** if not properly maintained.

- **Exhaust leaks** or cracked headers.

- **Clutch slippage** due to wear over time.

9. **Noise and Vibration** The single-cylinder engine is loud and can be vibration-heavy, especially at higher RPMs. Sound deadening or vibration dampeners may be needed for comfort.

10. **Limited Comfort for Long Rides** While great for short trail rides, the KLX-400S is not ideal for long-distance touring due to its basic ergonomics and lack of wind protection.

### **Ending Conclusion**

The **2003 2004 Kawasaki KLX-400S** is a **capable, budget-friendly off-road bike** that excels in trails, light motocross, and muddy conditions. It offers **reliability, simplicity, and upgrade potential**, making it a strong choice for riders who prioritize **performance, modifiability, and affordability** over modern conveniences. However, its **aging design, limited power, and maintenance needs** mean it s not ideal for **high-speed riding, daily commuting, or riders seeking a plug-and-play experience**.

If you re buying one **race-driven with upgraded brake pads (front/rear) and a "Mud Rat" setup**, it suggests the seller has already addressed some performance shortcomings. This could be a **good deal** if:

- The bike has **recent maintenance records**.

- The **suspension, brakes, and chain** are in good condition.

- You re **willing to invest in upgrades** (e.g., suspension, tires, exhaust) to match modern standards.

For **serious off-road riders on a budget**, the KLX-400S remains a **viable option** if you re okay with its limitations. However, if you want **more power, comfort, or modern features**, consider alternatives like the **CRF450L, RM-Z450, or newer KLX models**.

### **Recommendation**

You re a **trail or motocross rider** who prioritizes **lightweight, modifiability, and affordability**.

You **plan to invest in upgrades** (suspension, brakes, tires, exhaust) to improve performance and comfort.

You **don t mind basic ergonomics** and are okay with **regular maintenance**.

The bike has **clear maintenance history** and **no obvious rust or damage**.

You need **high-speed stability or highway capability**.

You want **modern features** (ABS, digital gauges, adjustable suspension).

You re **not mechanically inclined** and can t handle basic repairs.

The bike has **visible rust, leaks, or lacks documentation**.

**Final Verdict:** The **2003 2004 KLX-400S is a great project bike for off-road enthusiasts** who are prepared to put work into it. With the right upgrades, it can be **fast, fun, and reliable** but expect to **spend more on maintenance and modifications** than on a newer, more feature-packed bike. If you find one in **good condition with a fair price**, it s a **solid choice for the right rider**.
