- While powerful for its class, the **single-cylinder engine** can feel **less smooth and punchy** compared to multi-cylinder bikes (e.g., 400cc or 600cc sportbikes).
- **Vibration levels** can be noticeable at higher RPMs, which may be uncomfortable for some riders over long distances.
2. **Comfort for Long Rides**
- The **narrow seat and upright riding position** may cause fatigue on extended trips.
- The **lack of wind protection** (minimal fairings) makes high-speed highway riding less comfortable compared to adventure or touring bikes.
3. **Resale Value**
- Like many entry-level sportbikes, the **390 Duke depreciates quickly**, especially after a few years.
- Customized or heavily modified versions may hold value poorly in the used market.
