[long post, bottom line, make adjustments]
seems to be individual interpretation of 'comfort'..
for me [5'7"] its very comfortable, as in natural feeling
and relaxing positioning.. has been from the start,
but over time has become even more, comfortable..
as the seat formed into my shape i thought perhaps it
might become a bit hard, but its progressively better
fit to my backs of legs and glutes has resulted in moving
back bit by bit further towards the seat rear stop..
so my riding position has evolved into my body shape
and my riding position has improved generally to suit
the ergonomics of the bike, as well as increased comfort..
usually with my road bikes the handlebars would be loosened
and ridden around testing subtle differences, including lever
adjustments etc until my hands/arms/shoulders and so on
satisfied me.. with this on it felt a touch 'out' but not enough
to warrant adjusting,, so i waited to see, but have settled into
the position as assembled..
some recommend sitting with the back of the glutes downward into
the seat surface, ie, with a 'rounded' or 'hunched' back, but this seems
ridiculous and dangerous to the back [to me] whereas my position
is based on sitting on - the backs of my upper thighs - together with
the front area of. by glutes and pelvic floor..
this brings a nice potential for movement upwards from feet/pegs
thru knees taking the weight upwards a bit, such as for when
crossing an irregular road surface, bump or under road pipe crossing etc.
if/when we cross some unnoticed bump the upward force therefrom
goes into the thighs as well as the glutes, thus avoiding being fed
directly into and up the back [this is fundamental and pivotal to
general spine/back health for motorcycles, in my opinion]..
altho, after 6 mths on the bike and taking notice of ergonomics etc,
recently she got a yoshimura rear step plate kit, resulting in pegs
now back 45mm and up 30mm [with up 45mm option]..
this is a refinement of my own ergonomics, resulting in subtle but
relevant changes in general riding position, from foot on pegs
and gear/brake levers [about to make subtle changes to gear level]
with ball of foot migrating slightly forwards [easier shifting etc]
which is slightly more stable for adding pressure to pegs etc..
also, my lower back/bottom at about coccyx level now just
touches the rear seat stop or shades it when riding,
pressing back into it a little on acceleration..
as feedback to anyone interested in this aspect of
personal ergonomics in riding position i recommend
these step plates as easy fitting, quality, and doing what
i wanted from them [hard riders might go up 45mm]..
comfort is such an important factor in [everything] riding
the motorcycle that it should never be overlooked..
small adjustments in riding position and behaviours
plus adjustments in extremeties of reach [bars, pegs, seat]
are not difficult or major expenses, and should be part of
every motorcyclists general maintenance of their bike...
if your uncomfortable, there will be a reason for it..
same same in bed with a hard pillow or whatever,
you make adjustments until you are, comfortable...
provided you can actually fit onto the bike,
and ride it with normal ranges of body movement
then the answer to minor discomfort lies with
your own adjustments rather than with
the motorcycle itself as a 'thing'
you occasionally sit on...
