#### **Cons**

1. **High Initial Cost**

- A **new or well-maintained used Ski-Doo MXZ TNT 850** (especially with Renegade mods) can be **expensive**, often ranging from **$12,000 $18,000 ** depending on condition and modifications.

- **TNT suspension** is robust but may need **regular adjustments** for optimal performance.

3. **Weight**

- The **850cc engine and touring modifications** make this ATV **heavier** than smaller models (e.g., 500cc or 650cc ATVs), which can affect **maneuverability and fuel efficiency**.

- The **165mm wheels** add extra weight, which may impact handling on tight trails.

4. **Fuel Consumption**

- While better than larger engines, the **850cc MXZ still drinks fuel**, especially at highway speeds.

- Expect ** 30 40 MPG** in mixed riding (less on highways, more on trails).

5. **Learning Curve for Off-Road Use**

8. **Storage and Transport Challenges**

- The **size and weight** of the **TNT 850 with Renegade mods** make it **difficult to store in small garages** or transport in a standard trailer.

- If you don t have a **dedicated ATV trailer**, towing may be impractical for some riders.

- If you primarily ride **light trails or pavement**, the **extra power and modifications** may not be necessary.

- A **smaller ATV (e.g., 650cc or 500cc)** could be **cheaper to buy, run, and maintain** for casual use.

10. **Depreciation Over Time**

- Like most ATVs, the **MXZ 850 will lose value** over time, especially if not well-maintained.

- **Renegade mods** (while desirable) may not always increase resale value.
