I have lowered my 2021 MT-03
I purchased a Lust Racing rear lowering kit for my bike.
I'm 5.5 feet tall, My inseam is 28 inches...
Lust Racing kit lowers the rear shock 25mm
2019-2023 Yamaha MT-03 Lowering Kit, 25mm 1 in
Rear suspension lowering kit for Yamaha MT-03 by Lust Racing. Lowers the rears suspension and reduces the seat height. Will fit Yamaha MT-03, 2019 to 2023. Lowers the suspension and seat height by 25mm / 1.0 inches. Excellent modification for shorter motorcycle riders. Material 6061-T651...

Note:
I uninstalled the shock and took it to a all MC brands repair shop
You must have a MC shop install the Lust Racing lowering kit on the shock.
Shock spring is super heavy duty DO NOT try to install it yourself.
(MC shop labor for this job here in TN charged me $30)
Also pushed my fork tubes up 25mm in the Triple Trees to re-balance the suspension.
Also removed the seat cover and foam and built a new lower seat using a 5/8 inch gel-pad (Ebay),
with a thin top layer of yoga mat (Wal-Mart)
and then used black seat cover leather like waterproof vinyl (Hobby Lobby)
Results.... instead of toes only on both sides of the bike...
I'm flat footed on one side and have a slightly lifted heal on the other side with normal soul boots.
(You could also use thick soul boots to help also)
Bike handles like it was delivered new to me in 2021 after these mods...
I feel a-lot safer now...
Ooops... you must also shorten your sidestand....
I have recently installed one rear lowering spring the only tool extra you need is a spring compressorMel

I have to agree with @xorbe on this.... I'd like to add the geometry changes with every input you put into the chassis.... When I say that- I mean when you apply the front brake, it changes the steering geometry. This is a constantly changing variable- depending on the brake/lever force being applied at any given moment. I'm a "club racer" (on asphalt), and I can tell you that changing something as small as lowering the front end by as little as 10mm, it can make a HUGE difference in how the bike will corner. Most racers are HARD on the front brakes going into a corner- not only because it weights the front tire more, for better grip... But add to that, it also changes the steering geometry to help the bike tip-in to the corner better... There is math involved- that is WAY above my pay grade 
...
Manufactures' do a REALLY good job of balancing all of these variables out. They do an especially good job on entry level bikes like the R3/MT-03. I know it can be intimidating as a new rider when you are on a shorter side. I'm only 5'-6" tall, and I can ride a 450cc motocross bike with the techniques that the video shows. Once I'm "rolling", I don't give it a second thought. My best advice is to try to adapt to the bike, rather than adapting the bike to fit you. I know it may sound "counter-intuitive", but in the long run, you will most likely be better off for doing so-
