SV1000 is an underrated bike, gives you the best of nearly everything with a more comfortable riding position, excellent pillion accommodation(never had any complaints even on long rides) and it's great fun at the weekend.
The riding position on the 1000 is no different to the 650, and I found my 650 very uncomfortable for any significant distance. Even with a Suzuki gel seat my arse was in agony after about 70 miles. By comparison, my RSV is like a comfy old armchair that I can ride all day.
