- The **rotary valve system** improves airflow and efficiency, enhancing throttle response and power delivery.

2. **Versatility**

- The **Renegade 850** is designed for **snow, sand, and mixed terrain**, making it a good choice for riders who need a multi-purpose machine.

- The **adjustable QAS (Quick Adjust Suspension) system** allows for fine-tuning of suspension settings on the fly, improving comfort and handling.

3. **Comfort and Ergonomics**

- The **ergonomic seating position** reduces fatigue on long rides.

- The **adjustable handlebars and footpegs** help customize the fit for different riders.

4. **Durability and Build Quality**

5. **Aftermarket Support**

- The **QAS system** is modular, allowing for easy upgrades to **adjustable mount blocks** for further suspension tuning.

6. **Fuel Efficiency (Compared to Larger Models)**

- While not the most fuel-efficient, the **850 MXZ is more efficient than larger displacement engines**, reducing running costs compared to a 1000cc or higher model.

7. **Resale Value**

- Ski-Doo retains **better resale value** than many competitors, especially for well-maintained models.

---

#### **Cons**

1. **Higher Cost of Ownership**

- **Fuel consumption** is moderate but still higher than smaller engines (e.g., 500cc or 650cc models).

- **Maintenance and repairs** can be expensive, particularly for specialized parts like the **QAS suspension components**.

2. **Weight and Handling**

- The **850 MXZ is heavier** than smaller Ski-Doo models, which can make it less nimble in tight or technical terrain.

- Some riders find the **suspension settings** (even with QAS) less refined than on dedicated off-road or sand-specific machines.

3. **Noise and Vibration**

- The **rotary valve engine** is known for being **loud**, which may not be ideal for urban or noise-sensitive areas.

- At higher RPMs, **vibration can be noticeable**, though this is common in rotary-engine ATVs.

4. **Limited Off-Road Specialization**

- While capable of **snow, sand, and mixed terrain**, the **Renegade 850 is not as specialized** as models like the **Renegade 1000 for sand** or **Renegade 650 for snow**.

- Some riders prefer **dedicated off-road or sand machines** for extreme conditions.

5. **Complexity of QAS System**

- The **adjustable mount blocks and QAS suspension** add an extra layer of maintenance.

- Misalignment or improper adjustments can **reduce performance or cause premature wear**.

6. **Parts Availability and Cost**

- While parts are available, **specialized components (e.g., QAS linkages, suspension upgrades)** can be **pricier than stock parts**.

- Some aftermarket parts may not fit perfectly due to model-specific modifications.

7. **Age of Models (2016 2020)**

- These are **not the latest models**, meaning they lack **modern advancements** like **electronic fuel injection refinements, lighter materials, or advanced suspension tech** found in newer Ski-Doos (e.g., 2021 models).

- **Warranty coverage** may be limited or expired, increasing long-term repair risks.

---

### **Conclusion**

The **Ski-Doo Renegade 850 MXZ (2016 2020) with QAS adjustable mount blocks** is a **capable, versatile machine** suited for riders who need a **multi-terrain ATV** with **adjustable suspension**. It offers **strong power, durability, and aftermarket support**, making it a solid choice for those who prioritize **performance and customization**.

However, **higher maintenance costs, weight, and noise** may be drawbacks for some. If **budget is a concern**, newer models (2021 ) with **improved efficiency and tech** may be worth considering. If you **prioritize reliability, adjustability, and off-road capability**, this model remains a **good mid-range option**.

---

### **Recommendation**

- **Buy if:**

- You need a **versatile, adjustable ATV** for **snow, sand, and mixed terrain**.

- You **value the QAS system** for on-the-fly suspension tuning.

- You have **budget for maintenance** and **access to aftermarket parts**.

- You prefer **Ski-Doo s reputation for durability** over the latest tech.

- **Avoid if:**

- You require **extreme off-road or sand performance** (consider a **Renegade 1000 or 650** instead).

- You **hate noise and vibration** (rotary engines are loud and can feel rough).

- You want **lower long-term costs** (smaller engines or newer models may be more efficient).

- You **don t have time for maintenance** (this model requires more upkeep than simpler ATVs).

**Final Verdict:** A **great mid-range choice** for riders who want **adjustability and multi-terrain capability**, but not the absolute latest technology. If you find a **well-maintained example with service records**, it can be a **solid investment**. Otherwise, consider **newer models or specialized off-road ATVs** for better efficiency and performance.
