The 600 SS bikes don't get significantly better fuel economy than the 1000 SS bikes. There is more variation between individual bikes than there are between the two classes of bikes. Cane the heck out of 'em on the street? Mid-30's mpg for either. Cruise in top gear at 70 mph? 45ish mpg for either. The weight difference isn't that significant either, with the 1000's no more than 20 lb's heavier than the 600 from the same manufacturer. But, there is a significant difference in turn-in effort on the 1000's due to a much heavier crankshaft. A crankshaft built to handle 180 hp needs to be much larger and heavier than one built to handle 120 hp, and that is a huge gyro difference between the two types of bikes. On the street it isn't as noticeable since you're not trying to turn forcefully while the engines are way up in the rev range, but on track it's very noticeable.
