Here's a comparison made using
cycle-ergo. The site has limitations but I used it successfully to determine whether to substitute a C-bar for the RT-bar that was on my moto when I bought it. I bought the C-bar and it was comfortable. Now it has a Flanders sidecar bar which is more forward and has almost no rise. Anyway, a rider can slide further to the rear on the seat than this site can depict. The fairing might limit how far forward the legs can be extended, but it's certain that if engine protection bars were mounted, footpegs could be installed on them.
If you're riding on an unmodified stock bench seat, you should have it modified with more responsive and comfortable padding. That is what the Taintilator is all about. My moto's bench seat has been modified and I can ride comfortably all day and into the night on it.
The comparisons attached are based on a 5'10' rider with a 30" inseam, which I though might be dimensions that were close to those of many riders.
Here's how cycle-ergo shows the default riding position of a K100RS.
Here's how cycle-ergo shows the modified position I developed based on the fairing and footpegs installed on engine protection bars. I haven't ridden with a fairing so I'm guessing at its leg position restrictions.
