Whether you re restoring a classic Multistrada, upgrading an existing setup, or performing routine maintenance, this genuine Ducati part ensures seamless operation, reducing the risk of **valve float, excessive noise, or catastrophic failure** critical concerns for riders who demand both reliability and exhilarating performance. Its integration into the **Desmodromic valve train** underscores Ducati s commitment to precision engineering, delivering a balance of **durability, efficiency, and high-revving capability** that defines the brand s legacy. For enthusiasts and mechanics alike, this servo motor is an essential replacement part that upholds the Multistrada 1200 s reputation as a **versatile, high-performance adventure bike** capable of excelling on both pavement and off-road trails.

### **Pros and Cons of Buying a 2010-2011 Ducati Multistrada 1200 with a Faulty Exhaust Valve Servo Motor (Part Numbers 59340391A / 59340392A)**

#### **Pros**

1. **Strong Engine and Performance**

The Multistrada 1200 features Ducati s iconic 1,198cc L-Twin engine, delivering smooth power delivery, excellent mid-range torque, and a thrilling riding experience. The 1200cc displacement ensures strong acceleration and good highway stability, making it a capable adventure bike.

2. **Adventure-Bike Practicality**

The Multistrada was designed for dual-purpose use, offering a comfortable riding position, long-travel suspension (140mm front, 130mm rear), and a sturdy frame. It comes with practical features like a top case storage option, windscreen, and a relatively upright seating position, making it suitable for both road and light off-road use.

3. **Reliability of the Core Components**

Ducati s L-Twin engine is known for its durability, especially when maintained properly. Many Multistrada 1200 models from this era have proven reliable with proper servicing, and the bike s mechanical simplicity (compared to more complex modern bikes) makes repairs easier for experienced riders.

4. **Aftermarket Support and Customization**

The Multistrada 1200 has a strong aftermarket following, with availability of parts, upgrades (e.g., exhausts, suspension, handlebars), and tuning options. This makes it easier to modify the bike to suit personal preferences or improve performance.

5. **Resale Value and Niche Appeal**

Ducati adventure bikes, especially the Multistrada, hold their value relatively well due to their reputation for quality and versatility. While not as high-demand as newer models, they still attract buyers who appreciate classic Ducati engineering.

6. **Comfortable for Long Distances**

The ergonomics of the Multistrada 1200 are well-suited for touring, with a relaxed seating position, adjustable windscreen, and adequate suspension travel. This makes it a comfortable choice for riders who frequently travel long distances.

#### **Cons**

1. **Faulty Exhaust Valve Servo Motor (Part Numbers 59340391A / 59340392A)**

The most critical issue with these models is the failure of the exhaust valve servo motor, which controls the wastegate in the exhaust system. When this fails, the bike loses power, becomes difficult to control, and may stall or run poorly. The servo motor is a known weak point in these early Multistrada 1200 models, and replacement parts can be expensive (typically $300 $500 per servo, plus labor). Ducati has since improved this component in later models.

2. **High Maintenance Costs**

Ducati bikes, especially sportier or adventure models, tend to have higher maintenance costs than mass-market brands. Regular servicing, including valve adjustments, chain maintenance, and suspension tuning, adds up over time. The cost of labor and parts can be prohibitive for some riders.

3. **Weight and Handling**

The Multistrada 1200 is heavier than many modern sport or naked bikes, which can make it less nimble in tight corners or urban environments. While it handles well for its class, it lacks the agility of lighter bikes like the Yamaha T n r or Honda Africa Twin.

4. **Fuel Economy**

The 1,200cc engine is thirsty, especially when pushed hard. Expect around 30 40 mpg (urban/highway) depending on riding style, which is worse than many modern adventure bikes with smaller engines (e.g., 800cc 1,000cc models).

5. **Electronics and Modern Tech Limitations**

The 2010 2011 Multistrada lacks modern rider aids like traction control, ABS (though some models had optional ABS), or advanced fuel injection tuning. While this isn t a dealbreaker for purists, it can feel outdated compared to newer bikes with these features.

6. **Suspension Wear Over Time**

The suspension on these models is robust but not as advanced as later Ducati adventure bikes. After years of use, the shocks and forks may require replacement, adding to maintenance costs. The lack of adjustable preload on the rear shock can also limit tuning options.

7. **Parts Availability and Lead Times**

While Ducati parts are generally available, some aftermarket or rare components (especially for older models) may have longer lead times or higher costs than newer bikes. This can be frustrating if you need a part urgently.

### **Conclusion**

The 2010 2011 Ducati Multistrada 1200 is a capable and enjoyable adventure bike with a strong engine and practical features. However, the **exhaust valve servo motor failure** is a significant drawback that can turn a potentially great bike into a costly project if not addressed immediately. If you re comfortable with mechanical work or have access to a trusted mechanic, replacing the servo motor (or motors) is a necessary investment to restore the bike s performance.

For buyers who prioritize reliability and low maintenance, a **later Multistrada 1200 model (2012 )** with the improved servo motor or a **used 2012 model** would be a safer choice. Alternatively, if you re on a budget and willing to invest in repairs, a well-maintained 2010 2011 model can still be a rewarding project bike.

---

### **Recommendation**

- **Budget for the exhaust servo motor replacement** (or both if the other one is failing) upfront. This is a non-negotiable fix to avoid power loss and drivability issues.

- **Get a full service history** and inspect the bike thoroughly for other wear items (chain, sprockets, suspension, brakes).

- **Test ride the bike** to ensure the servo motors are functioning properly. A bike with a failing servo may not rev smoothly or lose power under load.

- **Consider the total cost of ownership**, including maintenance, fuel, and potential upgrades. Ducati bikes are fun but expensive to keep in top shape.

- **Avoid the 2010 2011 models** unless you re prepared to replace the servo motors immediately.

- **Look for a 2012 Multistrada 1200**, which features an improved (though still not perfect) servo motor design. Later models also benefit from minor refinements in electronics and ergonomics.

- **Alternative options:** If the Multistrada s price is too high, consider a **used 2012 Honda Africa Twin, Yamaha T n r , or BMW GS 1200**, which offer similar adventure capabilities with better reliability ratings and lower maintenance costs.

- The Multistrada 1200 can be a fun project bike, especially if you enjoy working on Ducati mechanics. However, be prepared for the learning curve of servicing the engine and electronics.

The 2010 2011 Ducati Multistrada 1200 is a great bike **if the exhaust servo motors are replaced and the bike is otherwise well-maintained**. For most buyers, however, a **later model or a different brand** would offer a more reliable and hassle-free adventure riding experience. If you re set on a Ducati, prioritize the servo motor fix and factor in the long-term costs of ownership.
