No, you're not crazy at all! It's not uncommon for motorcycle enthusiasts to have a strong attachment to their bikes, especially when they own multiple models from the same brand or series. The KTM Duke lineup, including the Duke 200 and Duke 390, has a dedicated fan base, and there are many riders who own and love both bikes.
Each model has its own unique characteristics and offers a different riding experience. The Duke 200 is known for its nimble handling and lower power output, making it great for city commuting and beginner riders. On the other hand, the Duke 390 is more powerful and geared towards performance, providing a thrilling riding experience.
If you enjoy both motorcycles and find value in owning and riding them, there's no reason to give them up if it's within your means. However, it's important to consider practical aspects as well, such as maintenance costs, storage space, and financial considerations. Discussing these factors with your wife and finding a compromise that works for both of you may help in resolving the situation.
Ultimately, the decision to keep or sell one of the bikes is a personal one, and it depends on your preferences, priorities, and circumstances. If you can find a way to manage both bikes responsibly and it brings you joy, there's nothing wrong with holding onto both of them.
