In my ever so humble opinion (tongue firmly planted in cheek), the answer to the question is a resounding: depends.
First, off it depends how aggressive one rides. The more so, the greater the need.
Secondly, it depends on how deep your pockets are. Are you gonna miss your rent/mortgage? Are you gonna be delinquent on your child support? Is your poodle/tabby/gold fish gonna go hungry? If so, this is not the proper time to allocate such funds.
Thirdly, do you do track days? If so, are you in a high+ "B" group? Be honest.
Fourth, is the rest of your brake system O.E.? If so, how soon will you improve that? If not very soon, this is not the time.
The next issue is touchy, that of touch sensation. Everyone is unique; thus, if you have below average touch sensation a high powered brake system could land one in the weeds. This is very serious business. Again, be honest. Super K could install a fabulous m/c, rotor, and lines. They intentionally dumb it down. One , to save money, two, to potentially save lives.
Again, humility requires my apologies to Sabotage, because even though brake system components don't jump out at the casual observer, say like new can, or LED turn signals, etc, suspension & braking components ought to be the second upgrades one ought to perform; second only to education - track days.
Go out to a track during a race weekend, as a spectator, and talk to various riders. Remember, they are not impartial, they have sponsors to chat up. What specifically do they like/dislike about their present system? Draw some rational conclusions. During heats, if you are able, go to the "tricky" spots and take notes of what's happening. If you are able, have a friend/spouse, etc also take notes - don't compare until later in the day.
The O.E. equipment that Super K puts on our bike is good, or good enough. If you are currently not routinely out riding your present system, you might think about investing in your moto-education. On the other hand if you are, than invest in the best suspension/braking equipment you can afford.
Don't be lazy, do your homework! Don't be a slave to fashion. But, if you are of a mind to get new lines & rotors if you currently do not have then, do this as a package. I almost never suggest installing multiple items at the same time, but this is the one. (I'd also suggest doing a new can and new ignition, CPU reflashing, DJ PC-V, etc at the same time).
I am presently running a Gale Speed m/c & complementing clutch perch (both come with lovely folding levers). Core Moto brake lines, and Brake Tech SS AXIS Cobra rotors; front and back. Yes, this represents a very pretty penny. I'd do it again in a heart beat. They are in fact that good.
Good luck hunting!😵🐾
