Review MOTORSPORT GASKETS M g Carbon Fiber Intake Reed Set Ktm fits 125EXC 125SX SX 125 1999–2003

The **M-G Racing R1247 Carbon Fiber Intake Reed Set (Part #731299488490)** is a high-performance upgrade designed exclusively for KTM 125cc single-cylinder models, including the **125SX, 125EX, and 125SX** (production years 1999 2003). Engineered to maximize airflow and throttle response, this precision-crafted reed set replaces the stock rubber reeds with a lightweight, high-strength **carbon fiber construction**, significantly reducing inertia and improving reed valve efficiency. The carbon fiber reeds are meticulously balanced to ensure smooth, consistent operation under high RPM conditions, eliminating the lag and flutter often associated with traditional rubber reeds. This upgrade is particularly beneficial for riders pushing their bikes to the limit, as it enhances mid-range power delivery and top-end acceleration, making the engine feel more responsive and aggressive. The R1247 set is compatible with the KTM 125 s stock intake system, requiring minimal installation simply remove the old reeds, clean the reed housing, and install the new carbon fiber reeds, ensuring a secure fit with the included O-rings for a leak-proof seal. Beyond performance gains, the carbon fiber reeds are also more durable than their rubber counterparts, resisting wear and deformation over time, which extends the lifespan of the intake system. Whether you're chasing faster lap times, improving off-road agility, or simply seeking a more engaging riding experience, this reed set delivers a noticeable shift in engine character, transforming the KTM 125 into a more spirited and efficient machine. Ideal for both track and trail use, the **M-G Racing R1247** is a straightforward yet impactful modification that proves even small components can make a big difference in overall performance.

### **Pros and Cons of buying a Motorsport Gaskets 731299488490 M-G R1247 Carbon Fiber Intake Reed Set for KTM 125SX/125EXC (99-03)**

#### **Pros:**

1. **Enhanced Performance** Carbon fiber materials are lighter than traditional metal or plastic, reducing unsprung weight and improving throttle response. The intake reed set is designed to optimize airflow, potentially increasing horsepower and torque.

2. **Durability and Strength** Carbon fiber is highly resistant to warping, cracking, or deformation under high temperatures and mechanical stress, making it a reliable upgrade for high-RPM applications.

3. **Better Airflow Efficiency** The reed set is engineered to minimize turbulence and maximize airflow into the engine, which can lead to smoother power delivery and improved acceleration.

4. **Compatibility** This specific part is designed for KTM 125SX/125EXC models from 1999 to 2003, ensuring a precise fit without modification. It replaces the stock reed set, which may wear out over time.

5. **Aftermarket Support** Motorsport Gaskets is a reputable brand known for high-quality aftermarket parts, and this product is part of their R1247 line, which is favored by tuners and racers for its performance benefits.

6. **Potential for Increased Reliability** If the stock reeds are worn or leaking, upgrading to this carbon fiber set can eliminate common issues like reed flutter or improper sealing, reducing engine stress.

7. **Aesthetic Appeal** Carbon fiber has a sleek, modern look that can enhance the visual appeal of the bike s intake system, though this is subjective.

#### **Cons:**

1. **Cost** Carbon fiber parts are generally more expensive than stock or basic aftermarket alternatives. This set may require a significant investment compared to OEM or cheaper reed replacements.

2. **Installation Complexity** While not overly difficult, replacing the reed set may require disassembling parts of the intake system, carburetor, or airbox. Those unfamiliar with engine work may need professional help, adding labor costs.

3. **Learning Curve for Tuning** Improving airflow can alter the bike s throttle response and powerband. The rider may need to adjust carburetor jetting or ignition timing to optimize performance, which could require experimentation.

4. **Potential for Overkill** If the stock reeds are still in good condition, upgrading may not offer noticeable benefits. This part is best suited for bikes that are already modified or used in racing/track use.

5. **Limited Longevity Claims** While carbon fiber is durable, extreme conditions (e.g., heavy track use, debris ingestion) could still cause wear over time. The lifespan may not be significantly longer than high-quality metal reeds.

6. **Compatibility with Stock Components** If other parts of the intake or carburetor system (e.g., filters, hoses) are degraded, upgrading the reeds alone may not fully address performance limitations. A holistic upgrade might be needed.

7. **Resale Value Impact** While not a major concern for most riders, heavily modified bikes with aftermarket parts like this may have lower resale value compared to stock or minimally modified units.

### **Conclusion:**

The **Motorsport Gaskets 731299488490 M-G R1247 Carbon Fiber Intake Reed Set** is a high-quality upgrade for KTM 125SX/125EXC owners who prioritize performance, durability, and airflow efficiency. It is particularly well-suited for riders who:

- Already have a modified or race-prepared bike.

- Experience issues with stock reeds (e.g., flutter, poor sealing).

- Want to reduce weight and improve throttle response.

- Are willing to invest in aftermarket parts for noticeable gains.

However, it may not be necessary for casual riders or those who haven t noticed performance degradation in their stock reeds. The cost and installation effort must be weighed against the expected benefits.

### **Recommendation:** **Buy this reed set if:**

- You are modifying your KTM 125SX/125EXC for track use or aggressive riding.

- Your stock reeds are worn or causing power loss.

- You are comfortable with minor engine work or have access to a mechanic.

- You want a lightweight, durable upgrade that enhances airflow.

**Avoid or reconsider if:**

- Your bike is stock or lightly modified, and the stock reeds are still functional.

- You are on a tight budget and can achieve similar gains with less expensive alternatives (e.g., high-quality metal reeds or carburetor tuning).

- You lack experience with carburetor or intake system adjustments.

For best results, pair this upgrade with other performance enhancements (e.g., high-flow air filter, tuned carburetor) and monitor the bike s response after installation. Always follow manufacturer guidelines for installation and tuning.
