aside from adjustable quality shocks etc,
and as you mention sitting position 'hugging tank
motocross style',, while changing ergos for rearward
hip movement isnt going to change suspension
reaction dynamics so much, it will change your
experience of, uneven upward road forces..
eg, taking speed bumps i tend to rise up on pegs
removing hips thus spine from sudden upward
jolt of the speed bump [speed regulating type]
even riding within surburban speeds..
back/spine isnt designed to take upward jolts
[other than its limited movement S-shape]
which are absorbed thru joint sequence from
toes thru ankles then knees and hip joints..
[try jumping up/landing, legs straight]
if [say] sitting slumped lounge style
with high bars and low forward pegs,
back is arched rearward bow-like
thus 'captured' by seat and subject to
upward jolting forces..
if hands/arms/shoulders are lowered,
feet moved rearward and upward,
now upper and lower joint sequences
have potential for absorbing jolts..
hips will naturally move rearward also
resulting in sitting on, in a riding position,
sitting bones rearward [rather than forward]
giving your natural S-shape spine potential
to further absorb jolt forces getting thru
your natural shock absorbing joints..
bottom line there is rearward hips
rather than motocross style hugging tank
is better generally, taking your mass
rearward but also allowing better responses
thru shock absorbing joints downstream..
easy way to test this is to ride with balls of feet
on pegs, pressing down slightly rather than
just resting on pegs, over some test jolt
such as typical speed humps etc..
as youve identified this motocross position
already, means brain has recognised something
relevant to balance, coordination and control
movements and responses in riding..
simply put, theres a time and place for everything,
including riding a motorcycle,, in motocross
or road racing or over other surfaces..
and reasons for/why, certain ergos are
appropriate or better for one riding style
and motorcycle, yet different for others..
