My K75 has the stock Corbin, a seat wifey will fall asleep on, it's so comfy. :clap:
The R1150 is the exact opposite. Worst seat in the history of motorcycling. :yow
Bought an Airhawk ("R" style - medium size) and rode from NY to Oregon for the MOA Rally, have done two SS1000's, and have nothing but praise for it. True, you do sit higher, but I have a 34" inseam, so a little extra legroom is a bonus. Monkey butt is a thing of the past. The air pad itself seems quite durable, has seen constant use for three years, and has held up well. The only weird thing is that if the bike is parked in the sun for a while, the air pressure increases, and it's firmer for a while until it settles down. Much better than spending the big $$$ for an aftermarket saddle.
BTW, it's been nice to re-discover Motobrick, and looking forward to sharing some of the enthusiasm for these good ole scooters.
Have owned this one for 16 years - three other bikes have come and gone - and the love affair is still going strong. :Rabia:
