I have not been on here for a long while. Went and got a VFR 800 FI, after my off on my 850 Mk2. Found the original seat a bit hard to take , and had to vacate after an hour or so on the road. I have since got a local car upholstery guy to shave a about 30 mm, off the top of the drivers seat position and insert a gel strip into this position. The difference is really good. 2 to 3 hours no stopping. It might be an idea. Goodluck !!!
