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-
