How does the FZ6R compare to dedicated tourers when used as a long distance tourer?

Although the Yamaha FZ6R is a sport oriented motorcycle by nature, it has earned the reputation among some riders to be a capable all rounder. Debates have ensued about its suitability for long distance touring compared to purpose built touring motorcycles. Riders talk about comfort over long distances, fuel range, luggage capacity, and wind protection. Some say that with a few tweaks, the FZ6R can make a decent tourer, while others say it's not up to scratch in the main areas. It’s a conversation that often includes personal experiences from those who have taken their FZ6Rs on long trips, comparing the FZ6R against dedicated touring bikes they’ve ridden. Bike ergonomics, seat comfort and ability to handle fully loaded touring are often mentioned factors. It also brings up the question of whether it makes more sense to modify an FZ6R for touring, or to buy a purpose built touring bike.
