It's all about confidence and approach, if your confident that your enough of a rider to handle it and you approach it with a degree of healthy fear and dread then I don't see a problem with buying a great big lump of a bike, but always remember it will kill you if you f**k up. Not being dramatic or anything just saying that is a hell of a stride from a 125 to a 1300. I have just bought an FJR 1300, I have been riding since I was 14, so about 50 years, and I am just about ready for this thing, you might be much better than me, lot's are, and have confidence oozing out of every pore in your body but it won't help when it gets away from you. Just sayin mind not trying to twist you either way.
