I havent had an issue with the GS but I have oned numerous Triumph speed triples and they had varying degrees of oil usage ranging from non to a litre every couple of thousand miles.
Thanks all, I really appreciate it, bikes been into Williams Manchester today and they have stated that it's perfectly normal and within BMW's specified tolerances for a 1250 to consume over a litre of oil every 1500-2000 miles. I'm surprised but they offered to show me the specs on the system but I declined as I don't think they are lying. Gonna be expensive to keep topping her up at that rate!
Did you run it in carefully and follow the manufacturers guidelines?
If so, that might be the issue.
There is a lot on anecdotal evidence that running them in hard, results in little/no oil usage later on.
If it’s within BMW tolerances then I guess you will just have to live with it. Hopefully the oil usage will drop off as things bed in.
