Stumble off the line and hesitation on 2019

[Henchman]

Its been having some noticeable issues, the throttle response used to be razor sharp, but now its sputtering and hesitating too, I've noticed it doesn't last long, mostly in the low revs, but it's enough to kill my flow in city riding and makes quick takeoffs embarrassing honestly, when it goes higher rpms it smoothens out though but something's clearly off, I know it, my fuel is clean and air filter passed her test
All and any help will be appreciated please, TIA

Have you thought about checking for any error codes? They could really help you figure out what's going on. Also, just a quick reminder to see if the bike has any aftermarket electronics installed, those can sometimes throw a wrench in things. And don't forget to double-check the tire pressure! Make sure that front tire is mounted to spin the right way, too. It's the little things that can make a big difference, you know?

Definitely fueling or sensor issues, I'd start looking at the throttle position sensor or even dirty injectors, maybe run down a scan

Modern bikes are so over-engineered with sensors and electronics that they've lost the simplicity and reliability older models had, now a minor glitch in throttle response turns into a diagnostic rabbit hole no one asked for...crazy!

You're kidding, right?

@Henchman have you checked the spark plugs? They could be causing this. The possibility of carbon buildup is also there, so you may need to do a bit of tear down or take it to a shop.
