Sargent is Excellent
Have had the M1100S for a month. Three weeks in I was ready to chuck the stock seat. Was worried because although the seat is crap, I was convinced that the real flaw was the way the tank curved too far towards the rider's crotch, so I was unsure that the Sargent would be a real fix, even though it is much flatter than the stock.
Have had the Sargent for a week and love it. Did a weekend ride, 8 hrs each day through mountain sweepers, twisties and some interstate, and it was amazing.
I've had a Sargent on my previous SV1000S and although it was very different (more of a scooped pan shape with harder edges than the Sargent Monster's higher saddle with softer sides that drop off more), both were huge improvements.
I'm 6'1" 185 lbs and the seat is just right height-wise. For sub-6' riders I would suggest the low version, not just for flat-footed stops but shorter arms will require a slightly more bent-over upper body riding position with a tall seat.
The look of the seam across the back of the rider's section of the seat looked strange to me in the pics online but I find the seat is actually much nicer than stock. I have the black welts on mine which look good with the white paint scheme.
Another member posted that the correct riding position on all monsters is butt pushed all the way back to the seatback. I think this is rider size dependant. If I push to the back of the seat my crotch is about 4" away from the tank - not great for sport riding.
Though expensive, I agree with those who say it's the best mod. I'm sure ecu reflashes and PCV and autotunes and such affect performance in a very positive way, but the seat upgrade fixes the very real and uncomfortable penis/testicle-crushing tendency of the Monster with stock seat. This, to me, is THE priority.
