Here is a report on the Russell Day Long seat from rider and pillion perspective.
We only had the opportunity due to other comitments to do a 200km ride today.
Rider - Chris found the seat very supportive with its wrap around shape and support underneath the upper part of his thighs. He has never felt the need to slide off the seat when cornering but was concerned that this would be an issue, and found the complete opposite, that the seat supported you on that side of your body whilst cornering.
Chris has his seat in the middle height setting at the front and the second lowest at the rear, and the seat just bekons for you to use the high way pegs more often.
Pillion - I found the seat a little slippery in my textile pants, but because of the scollaped cut of the seat I had no side ways movement and only minimal forward movement. The seat was extremely comfortable and supportive overall and I feel I could travel far greater distances that I could ever travel on the Honda seat with the air hawk and sheep skin cover although they were a great time addition to the Honda seat.
I found the seat about 2.5cms higher than the standard seat and didnt need to look around Chris as much as I used to. The only negatives that we could find was from a riders point of view Chris needed to slide forward a little to put his feet down, but is getting used to it, and from my point of view with my lack of height, standard pegs may have been a struggle for me to reach with the increased seat height, but thats been solved prior to this with raised foot pegs.
So overall as a long distance touring seat we dont know how it could be made better.
Pockey and ST2UP.
