Here is the Nelson-Rigg MC-902-04 in X-large on my 2014 with OEM panniers and tall windscreen. I bought it as a dust cover and deterrent for curious throttle twisters in my apartment complex garage. For the price, it seems like a decent solution for this purpose.
FWIW I had a Sargent seat on my BMW R1200R. It improved over time and after a year or so was an all day seat. Interestingly I also recall it was slippery but I guess I got used to that.
Just joined the S10 community yesterday morning. Picked up this 2014 with less than 10K miles. Jumped from BMW to the Ténéré, a bike that caught my eye several years ago. Looking forward to running with a new crowd and already grateful to have the resource of this forum.
Cheers!
