At the end of the day, it also depends a lot of where we live and what type of traffic each one faces.
Of course, this is a 1000cc bike, and in highway there is no doubts it will suck more fuel. What is very variable is facing the traffic, and cruising regarding the type of road.
I think thats why a lot of us get such different mileage in the same bike. Each one of us has different types of riding conditions, different style of driving... but we all have pass through all of them in many situations, and I think it's more "fair" to catalogue it in categories, and so others can fit themselves in the right categorie.
So if we had to descriminate, I will separate this in 3 main types:
- Highway (85 mph)
- Cruising (50-60 mph)
- City with some traffic
which values do you get in your bikes?
