I can’t begin to imagine how much “fun” it is to be searching for fuel every 75 miles, the Multi V4S is billed as a sporting tourer so a reasonable tank range is a prerequisite whereas on the street fighter it’s neither expected or it seems required, horses for courses. My experience tells me that on my V4 Multi I can get a similar range to other bikes I’m travelling with, stying in sync at fuel stops helps and saves time when travelling in a group.
Considering other folk you’re riding with Steve? You’ll end up getting chucked off the forum!
