Review SUZUKI Oem Model Power Valve Exhaust Side Lh fits RM250 1999–2000

The **Suzuki 11256-37E30 (1999 2000 model year) RM250 Power Valve Exhaust System (Left-Hand Drive, LH)** is a precision-engineered component designed to enhance the performance, sound, and efficiency of the iconic Suzuki RM250 motorcycle. This exhaust system is part of Suzuki s **Power Valve** lineup, a series of high-performance exhausts crafted to optimize airflow while delivering a deep, aggressive tone that resonates with both street and track enthusiasts. Built to replace the stock exhaust on the 1999 and 2000 RM250 models, this unit features a **dual-chamber, dual-pipe design** with a **catalytic converter** (where applicable, depending on emissions regulations) and a **stainless steel construction** that ensures durability and resistance to corrosion. The exhaust incorporates a **variable geometry system**, allowing the power valve to modulate exhaust flow at different RPM ranges, improving mid-range torque and high-end power delivery. This results in a more linear and responsive throttle, making the RM250 feel more agile and engaging, whether you're navigating tight corners or pushing through the top end. The **LH (Left-Hand Drive) configuration** ensures a perfect fit for riders in markets where the bike is driven on the left side of the road, eliminating any compatibility issues. Crafted from **high-grade stainless steel**, the exhaust system is designed to withstand the rigors of daily riding, off-road adventures, or track days, maintaining its performance and appearance over time. The **sleek, aggressive styling** of the Power Valve exhaust not only enhances the RM250 s sporty aesthetic but also contributes to its distinctive, throaty exhaust note a hallmark of Suzuki s high-performance exhaust systems. Whether you're looking to improve your bike s power output, refine its sound, or simply upgrade its looks, this exhaust system delivers a noticeable improvement in both performance and character, making it a standout choice for RM250 owners who demand the best from their motorcycle.

### **Pros and Cons of Buying a 1999-2000 Suzuki RM250 with the Specified Exhaust (11256-37E30 for LH, 11256-37E31 for RH)**

#### **Pros**

1. **Classic Dirt Bike Design** The RM250 is a well-regarded trail bike with a simple, durable design that appeals to riders who enjoy off-road riding without excessive weight or complexity. Its lightweight frame and efficient 249cc single-cylinder engine make it a great choice for beginners and intermediate riders.

2. **Reliability and Durability** Suzuki s RM250 is known for its robustness, especially in older models like the 1999-2000 versions. With proper maintenance, these bikes can last for decades with minimal major repairs. The engine is straightforward, with fewer components prone to failure compared to modern multi-valve or turbocharged bikes.

3. **Affordability** Used RM250s from this era are relatively inexpensive compared to modern trail bikes, making them an attractive option for budget-conscious riders. Parts are also widely available and often cheap, reducing long-term costs.

4. **Simplicity and Ease of Maintenance** The RM250 s design is simple, with a carbureted engine and basic suspension (usually 21-inch front and 19-inch rear forks). This makes it easier to diagnose and fix issues without specialized tools or expertise. Many mechanics are familiar with Suzuki s older models.

5. **Off-Road Capability** The RM250 is built for trail riding, with a low seat height, lightweight frame, and a gearing ratio optimized for climbing and descending. It s not as aggressive as a motocross bike but excels in light trails, cross-country riding, and casual off-road adventures.

6. **Resale Value** Suzuki s RM series holds its value reasonably well, especially for well-maintained examples. The 1999-2000 models are still sought after by riders who prefer the classic look and feel of pre-2000s dirt bikes.

7. **Exhaust Upgrade Potential** The stock exhaust on the RM250 can be noisy and restrictive. The **11256-37E30 (LH) / 11256-37E31 (RH)** exhaust is a common aftermarket upgrade that reduces weight, improves exhaust flow, and can enhance mid-range power slightly. It s a straightforward swap that many riders opt for to improve performance and reduce noise.

8. **Community and Support** The RM250 has a dedicated following, with forums, clubs, and aftermarket parts readily available. This makes it easier to find help, modifications, and accessories if needed.

#### **Cons**

1. **Outdated Technology** The RM250 lacks modern advancements like electronic fuel injection (EFI), disc brakes (early models have drum brakes), and advanced suspension tuning. This can make it less efficient, less comfortable on rough terrain, and harder to control at high speeds compared to newer bikes.

2. **Poor Braking** The stock braking system on the 1999-2000 RM250 is a single disc in the front and a drum brake in the rear. This is inadequate for modern trail riding, especially if you plan to ride at higher speeds or on technical terrain. Upgrading to disc brakes (aftermarket) is often necessary for safety.

3. **Weak Power Delivery** The 249cc single-cylinder engine produces only about 20-25 horsepower, which is sufficient for light trail riding but feels underpowered compared to modern bikes. The powerband is narrow, and the bike struggles with heavy climbs or aggressive riding styles.

4. **Comfort Limitations** The RM250 s ergonomics are basic, with a stiff seat, minimal suspension travel (especially on stock forks), and a cramped riding position. Long rides can be uncomfortable, and the bike is not ideal for heavy riders due to its lightweight frame.

5. **Fuel Efficiency Concerns** While the RM250 is fuel-efficient by dirt bike standards, the carbureted engine can be finicky with fuel quality and altitude changes. Modern fuel blends may not work as well as older fuels, potentially leading to performance issues or drivability problems.

6. **Noise and Vibration** The stock exhaust is loud, and even with an aftermarket upgrade like the **11256-37E30/31**, the bike remains noisy. Vibration levels are also high due to the single-cylinder engine, which can lead to fatigue during long rides.

7. **Limited Modern Modifications** While the RM250 is mod-friendly, many modern upgrades (e.g., high-performance airboxes, advanced suspension, or electronic ignition) are not natively compatible. Aftermarket solutions are available but can be expensive or require significant effort to install.

8. **Rust and Wear Issues** Older bikes, especially those from humid or snowy climates, may suffer from rust in critical areas like the frame, suspension, and exhaust. A thorough inspection is essential to avoid buying a bike with hidden structural issues.

9. **Legal Restrictions** Some regions have noise or emissions regulations that may restrict the use of older dirt bikes, especially if they lack modern safety features like ABS or electronic stability control (though these are rarely required for off-road use).

10. **Depreciation** While the RM250 holds value better than many dirt bikes, it will still depreciate over time. If you plan to sell it later, the resale value may not justify the cost of extensive upgrades or maintenance.

### **Conclusion**

The **1999-2000 Suzuki RM250 with the aftermarket exhaust (11256-37E30/31)** is a solid choice for riders who prioritize simplicity, affordability, and a classic off-road experience. It s ideal for:

- Beginners learning to ride.

- Riders who enjoy light trail or cross-country adventures.

- Those who prefer a no-frills, low-maintenance bike.

- Enthusiasts who appreciate the nostalgia of older dirt bikes.

- Riders seeking high performance or aggressive trail riding.

- Those who prioritize comfort, braking, or modern safety features.

- People who plan to ride heavily or in demanding conditions (e.g., steep climbs, technical descents).

The **exhaust upgrade** is a worthwhile modification for most owners, as it reduces weight, improves exhaust flow, and lowers noise levels. However, it s just one of many potential upgrades (e.g., suspension, brakes, or engine tuning) that may be needed to make the bike more enjoyable or safe for modern riding.

---

### **Recommendation**

1. **Inspect Thoroughly** Look for rust, frame cracks, suspension leaks, and engine wear. Test the brakes, suspension, and throttle response. A pre-purchase inspection by a mechanic is highly recommended.

- **Disc brakes** (front and rear) for better stopping power.

- **Suspension upgrades** (e.g., Ohlins or WP forks) if you want improved comfort and performance.

- **Fuel system tweaks** (e.g., a better carburetor or aftermarket airbox) if the bike runs poorly.

- **Tires** (modern off-road tires like Maxxis Rekon or Michelin Wild Rider are a must).

3. **Test Ride** Spend time on the bike to ensure it feels comfortable and responsive. Pay attention to vibration, handling, and power delivery.

4. **Consider Alternatives** If you re open to spending slightly more, modern trail bikes like the **Honda CRF250L, Yamaha WR250R, or Kawasaki KLX230** offer better braking, suspension, and power while still being affordable. For a more aggressive ride, a **Yamaha WR250R or KTM 250 XC** might be worth the extra cost.

5. **Buy from a Reputable Seller** Prefer dealers or private sellers with a history of honest transactions. Avoid "project bikes" unless you re prepared for extensive work.

6. **Maintain It Properly** If you buy this bike, commit to regular maintenance (oil changes, chain care, valve adjustments) to keep it running reliably.

---

**Final Verdict:** The **1999-2000 Suzuki RM250 with the aftermarket exhaust** is a great **budget-friendly, low-maintenance trail bike** for casual riders or those who enjoy the simplicity of older dirt bikes. However, it requires upgrades to be truly safe and enjoyable for modern riding. If you re willing to invest in modifications, it can be a fun and rewarding bike. If you want a more capable trail bike out of the box, consider a newer model with better brakes and suspension.
