Still in break-in mode, so I'm not flogging her....yet. Just did my third fill-up, averaged 51mpg. This was also a test of how many miles I can get once the fuel lite comes on. Low fuel lite came on @ 131miles and rode another 48 miles until I chickened out and topped up.
I myself have never took it easy apart from 1st 600 miles, I ride hard and I think most do, and average 50+mpg it may be a problem on your bike. Here's an extract from BIKE magazine on their long term test hyperstrada.
"it's efficient, readily giving 50 mpg in normal riding and can be pushed to 60mpg without much thought"
I'm not saying there is a problem, just might be worth getting it checked out when next in the dealer?? Just seems strange you can't get nearer the higher mpg range.
You'll read one or two posters that achieved 200 miles. I can't imagine how boring that would be.
