With my height I barely get my toes to touch the ground.
I am planing to lower my Bike by 3 inches.
Is that going to be too much. Will the bottom of the
bike touch the ground on uneven path?
Thank you.

Can't:
Lower the forks. Taper begins below the bottom pinch point of the lower triple tree.
Remove spring length. Or the few or so inch will bottom out the leg onto the brake mount lower [for a better term].
Lower the rear spring ring any higher than minimum book value. Or when you hit a bump, the ring bangs on the spring.

Can:
Lower seat height.
Sit off the bike like Marc Marquez is half ass off the seat. This way, more leg on the left side hitting the ground, and right leg stabbing the rear brake pedal if needed.
Swap front end so fork legs are old style and you can slide them up the fork crowns.
Make a bracket so the same geometry is to lower the swing arm, and enough travel to not bang shock mounts, nor bottom out under the fender well.

What I miss?

Well Hub.Ya didn't miss anything.BUT...He could get some lowering links for the rear,maybe Brocks.Then lower the front equally,an inch at least.AND reshape his seat for a lower height.That should give him enough drop to be very close to flat footed.???I wouldn't go for 3 inches.Gonna have scraping issues I think on compressions.
He can lower that front 1" at least with the stock forks.

16" rims.

I would order a used OEM seat off of Ebay and cut most the foam out of it. That will probably make you need to have your legs wider apart when you put your feet down though. It would lower the seat height by two inches though. Try sitting on the bike without a seat and see if that seems safer.

I went down about half inch on my 2015 with lowering links and dropping forks through the tree. Night and day for flat footing. Im 5’8 barefooted

I'm 5'9" so I have no problem getting flat footed BUT I have a friend with a 14r who is 5'5". He got a pair of boots with 2 inch heels then he inserted a 2 inch lift into his boots and now he can get flat footed. You might try that first.

2013 ZX14R. I am 5'6" with 28 inch inseam , about 128 pounds outta the shower . Took the forks all teh way up as high as they could go ( 1 1/2 inches) and put Brocks adjustable lowering links on at 1 3/4 inches ..with stock seat , I can just get bare feet flat.. With my race seat , which has less than an inch of foam under the cover now, I am quite comfortable on the bike I also have 1 1/2 inch risers which makes traveling a bit more enjoyable.

I am 5'7" in height and 29" inseam. I got satisfactory results by:

- having a pro motorcycle seat upholsterer carve out my seat at the front to lower it well over an inch without making it uncomfortable to ride. I was amazed at how good a job the upholsterer did - I never ride more than 2.5 hours non-stop, and the lowered seat gives me no issues even at the end of 2.5 hours/

and

- moving the footpegs rearward (via aftermarket kit) so that the new rearward positioning allowed my lower legs to clear the pegs and reach the pavement easier. I also adapted a gearshift lever from a salvage shop that could be mounted rearfacing (like the stock ZX-14R lever) but was a bit longer, to make the distance from footpeg to lever peadal same as before.

I am flatfooted at stops now.
