Just received and repackaged a Corbin F3 dual seat - at least they offer one remake under the guarantee but that is not really the issue.
I didn't think about it when I checked it out online but these are the ergonomic differences compared to the original seat.
Corbin seat is:
1) 3" longer in the rider's saddle, measured from the tank cap
To sit on the slightly more comfortable part of the saddle moves you at least 2" further back from standard, which means longer handlebars and a new brake rod (to move the footrests back as well). We won't do that because:
2) Abut 1/2" lower in the saddle.
There is only 1.5" of saddle foam, at the most, in the deepest part of the saddle where your buttocks rest. Not even Corbin's ultra-firm closed-pore foam will give you enough comfort with that small amount of protection from the hard, irregularly-shaped base.
I am getting them to add 1.5" of foam to the squab (or backrest portion) to bring us further forward, and 1.5" to the base so we have some more comfort, actually twice as much comfort, to be precise. Foam, like any constant rate suspension medium, gets softer as you increase its depth or "length".
3) About 1" shorter in the pillion seat, even though the seat ends at least 1/2" further back than the oem one.
This makes for a tight squeeze between your privates and the rider's backrest, if one is fitted; too tight, in fact.
Because I am having the back of the rider's seat moved forward we won't be able to fit a rider's backrest - the original mounting point is moulded into the seat and so cannot be relocated.
However, the pillion part of the one-piece seat does have a Corbin advantage or bonus:
4) About 1" higher in the pillion seat.
This extra depth of dense seat foam (it's about 4" thick) makes for a very comfortable ride. We went for a 90 minute ride the other day and it felt great - now the challenge is to get similar comfort on the front (rider's) portion with just 3" of foam. It also allows my legs to stretch out a little more.
After using the amply proportioned Corbin seat for a week I find the original rider's seat a little cramped now that I have had to refit it, but I will get used to that again.
If you are thinking of getting one check all the pics online on the web site. The seat has definitely been redesigned for the folk with ample buttocks, rather than average. Maybe they make up the bulk of F3 riders now?
