Hi, I just looked at and rode a very cherry ´03 r1150st, 12K miles. I liked it and am leaning toward purchasing. I´ve been riding a Valk interstate for 30+K miles and still really dig it. I´m torn. My questions are: what are the maintenance reqs? Are ABS a costly upkeep item. What kind of fuel mileage? run supreme or reg?How much do you like your´s? I´m worried about the maint costs. Thanks for any help you can give me. new guy marcus
