Review SUZUKI Intake fits RM125 1986–1988

The **Suzuki 13111-01B20 Intake Kit** is a meticulously engineered aftermarket component designed specifically for the **RM125** motorcycles produced between **1986 and 1988**, ensuring optimal performance, improved throttle response, and enhanced airflow for these iconic lightweight bikes. Crafted from high-quality materials, this intake system replaces the stock airbox assembly, featuring a **durable plastic housing** with precise internal routing to minimize turbulence and maximize efficiency. The kit includes a **smooth-bore intake tube** that seamlessly connects to the carburetor, reducing backpressure and allowing the engine to breathe more freely, which translates to better fuel atomization and a cleaner, more responsive combustion process. For riders seeking a balance between ease of installation and noticeable performance gains, this intake kit is an excellent choice, as it requires minimal modification to the stock setup while delivering measurable improvements in power delivery and overall engine efficiency. Whether used for daily commuting or light track use, the **13111-01B20** ensures that the RM125 s reliable yet understated engine operates closer to its potential, offering a subtle yet satisfying upgrade for enthusiasts who appreciate both simplicity and performance.

### Pros and Cons of Buying a Suzuki 13111-01B20 Intake for a 1986 1988 RM125

#### **Pros:**

1. **Performance Improvement** The 13111-01B20 intake manifold is designed to enhance airflow into the engine, which can improve throttle response, power output, and overall engine efficiency. For an RM125, which is a lightweight and simple bike, even modest gains in airflow can make a noticeable difference in acceleration and top-end speed.

2. **Ease of Installation** Suzuki parts are generally well-documented and widely available, making this intake manifold relatively straightforward to install. Most mechanics or experienced DIY riders can fit it without extensive modifications to the bike s existing setup.

3. **Cost-Effective Upgrade** Compared to other performance modifications (such as carburetor tuning, exhaust upgrades, or engine rebuilds), replacing the intake manifold is a relatively inexpensive way to boost performance. The part itself is often affordable, and labor costs are minimal if you handle the installation yourself.

4. **Compatibility** This intake manifold is specifically designed for the 1986 1988 RM125, ensuring a proper fit without the need for additional adapters or modifications. It maintains the bike s stock engine management characteristics while improving airflow.

5. **Durability** Suzuki parts are known for their durability, and this intake manifold is no exception. It is built to withstand the stresses of daily riding and performance use, provided it is installed and maintained correctly.

6. **Maintains Stock Feel** Unlike aggressive performance kits that drastically alter the bike s character, this intake manifold provides subtle improvements without making the RM125 feel overly aggressive or unstable. It retains the bike s nimble and responsive handling.

7. **Potential for Further Tuning** If you plan to make additional modifications (such as upgrading the carburetor or installing a performance exhaust), this intake manifold can serve as a solid foundation for those upgrades. It allows you to fine-tune the bike s performance incrementally.

#### **Cons:**

1. **Limited Power Gains** While the intake manifold will improve airflow, the gains in power may not be dramatic. The RM125 s engine is relatively simple and not designed for high-performance modifications. Expect modest improvements in acceleration and top speed rather than a significant power surge.

2. **Requires Carburetor Adjustment** Installing a new intake manifold may necessitate recalibrating the carburetor to match the improved airflow. If the carburetor is not adjusted properly, the bike could run lean, leading to rough idling, overheating, or reduced fuel efficiency. This may require a visit to a mechanic or some trial-and-error tuning on your part.

3. **Potential for Voiding Warranty (If Applicable)** If the bike is still under warranty (unlikely for a 1986 1988 model), installing aftermarket parts like this intake manifold could void any remaining coverage. Always check the warranty terms before proceeding with modifications.

4. **Minimal Impact on Low-End Torque** The RM125 s engine is already quite nimble and responsive at low speeds. The intake manifold may improve mid-to-high-range performance but may not significantly enhance the bike s low-end torque or starting characteristics.

5. **Installation Challenges for Inexperienced Riders** While the installation is generally simple, it does require some mechanical skill. If you are not comfortable working on motorcycles, you may need to pay for professional labor, which could offset some of the cost savings.

6. **Compatibility with Other Mods** If you plan to install other performance parts (such as a different carburetor or exhaust), you may need to ensure that the intake manifold is compatible with those upgrades. In some cases, additional modifications (like flex lines or adapters) may be required.

7. **Environmental and Legal Considerations** In some regions, modifying a motorcycle s intake system may require compliance with emissions standards or noise regulations. While the RM125 is an older model and likely exempt from strict modern regulations, it s worth checking local laws to avoid potential issues.

### **Conclusion:**

The Suzuki 13111-01B20 intake manifold is a worthwhile upgrade for a 1986 1988 RM125 if you are looking for a simple, cost-effective way to improve airflow and performance. The benefits such as better throttle response, modest power gains, and ease of installation outweigh the drawbacks for most riders, especially those who are not planning extensive modifications. However, the gains are not revolutionary, and the upgrade does require some basic mechanical knowledge or a willingness to pay for professional installation.

If you are satisfied with the bike s stock performance or are not interested in further tuning, this modification may not be worth the effort. On the other hand, if you enjoy tinkering with your bike and want to enhance its handling and acceleration without a major overhaul, this intake manifold is a practical choice.

---

### **Recommendation:** **Buy the intake manifold if:**

- You want a straightforward and affordable way to improve your RM125 s performance.

- You are comfortable with basic mechanical work or have access to a mechanic for installation and carburetor tuning.

- You plan to make additional minor modifications (e.g., carburetor adjustment, exhaust upgrades) in the future.

- You value the bike s stock character but want subtle enhancements in acceleration and top-end speed.

**Avoid the intake manifold if:**

- You are not interested in any modifications and are happy with the bike s stock performance.

- You lack the mechanical skills or tools to install it properly, and professional labor costs would make the upgrade less cost-effective.

- You are planning aggressive performance modifications (such as a full engine rebuild or aggressive carburetor tuning), as the intake manifold may not provide significant additional benefits.

- You are concerned about warranty voids or legal restrictions in your area.

**Final Verdict:** For the average rider looking to breathe new life into their RM125 with minimal effort and expense, the Suzuki 13111-01B20 intake manifold is a solid and recommended upgrade. It strikes a balance between ease of installation, cost, and performance gains, making it a practical choice for those who enjoy customizing their bikes without overcomplicating things.
