If you like & are comfortable with the more upright riding position experienced on an STS, especially on your daily commute, you might want to first test ride an F3 for a similar length ride, just to make sure that you'll be equally as (or more? :dontknow: ) comfortable on an F3 where you'll have a more '
semi-reclined with feet forward' stance, sorta similiar to the '
birthing position' seen by the occupant of an obstetrician's table with their feet in the stirrups! :shocked:
While the F3 saddle on all models
is appreciably lower and they can be easier to climb onto as a result, once you're aboard, the F3's seating and riding position basically forces all of your weight onto your tailbone & butt, with no way of alleviating that for very long by supporting yourself/taking your weight on your feet &/or legs; altho the 'foot forward' riding stance
does allow you to push more on the outside foot during hard cornering and get your legs much more involved in the 'body english' required to really hustle these Spyders/Rykers thru the twisties!

hyea: The U-fit system for foot peg/board positioning will allow you to tailor how much you get to stretch out your legs; while the various 'reach' bars let you choose how far forward you get to fold yourself in the middle while riding, or how far back you can recline; but there's
no way to adjust anything to allow you to get your weight off your tailbone &/or lower spine!! :sour: So if you're not up to handling that for as long as you need to ride, then the F3 might not be the ideal Spyder model choice for you!! :dontknow:
