I had a Sargent on my GSF1250 Bandit, and it was very comfy. When I was looking at one for the VStrom, I did not like the Sargent version, I wanted to lower the pillion hump for more room and raise the front for more leg room, plus the cost of the Sargent is pretty costly. I found a bloke in Coventry C M Seats
www.cmseats.comMe and my mate both had seats reworked, I had the basket weave, raised height, gel pad, pillion hump lowered and moved back slightly. My mate had the basket weave and gel pad. They took about 8 days, we delivered and they posted them back. Cost around £200. We both find them very comfortable and I have more room to move around on it. Don't use Bike Prep on them though, they turn into a skating rink.
