I called Russell 2 hours ago about my order which starts TOMORROW, the 25th. I asked about the height of the seat they are making for me vs. the stock seat I sent them. I'm right at 6 ft. He told me that it might be 1/2 inch higher than stock but would settle down after some miles. As taxfree pointed out in his video, you'll slide back and down a bit when you take off, and slide forward at a light to flatfoot, etc. If I end up a little higher, I'm OK with it. Almost anything is better than the stock convex crap you get when new. My last MC was a Harley Street Glide and I bought a Harley police solo seat with the air compressor, etc. I could ride in that seat till the tank went dry. To me, the Russell is somewhat analogous to the police solo seat in shape and width. Also similar to a tractor seat with foam rubber. Those seats are shaped like your butt, not a watermelon. I think that if you tell Russell what you need, they'll do their best to make it happen. Best seat I ever had was the EZ BERG seat for my old Moto Guzzi Eldorado back in the late 70's. All it needed was a 40 gallon gas tank.
I've had 2 RDL's I didn't noticed the seat being any higher. 9 hours on a V-Strom, stopped for fuel & a sandwich. Got off my butt was smiling! no aches, pains, stiff joints, felt great the next day too.
My RDL does sit me a little higher, but when I sit all the way back, I feel more "planted" into the bike than I did with the stock seat. I tried a Mustang seat and it definitely sits you down and into the bike, but man that thing hurt after about an hour and a half of riding. There is only so much that can be done with the seats.
