Finally, these records are exact - I think it would be very difficult to guessitmate the costs of running a bike.
It wasn't difficult at all, it was dead easy and took me less than 5 mins.
Apart from the fuel, which is irrelevant, it's within a hundred pound pa either way and is, as you say, a guesstimate.
It was curiousity. Dull but harmless.

I just wanted to put a counter figure in there because yours, while wholly accurate, is the the true cost of running your 1150GS not 'a' 1150GS, if you can excuse the pedantry, and therefore perhaps not what many owners could expect.
As far as fuel goes when I get a different car, bike I often find it interesting to calculate an average over a few tanks and then after that I just forget about it. I can tell you I did my first big weekend trip on the Guzzi a few weeks ago and over 4 tanks & 800 miles the worst was 46, best was 52 and the average was 49mpg.......most I saw on the odo was 214 miles but she stalled at the last 2 junctions before I rolled onto the forecourt having past 3 closed station that night .

Ignore the knockers who say "just get out on your bike and ride it". If working that kinda stuff out is interesting to you and you have the time to do it & share it on an owners forum then good for you...
