Hi guys!
recently purchased a brand new 2021 Ninja 650L(limited, Australia, we have power / weight ratio restriction) previously had a 250 i used to practice on.

i was wondering, what is the process in un-restricting these? given i get off my restrictions in a few months and i dont really want to trade it in for a standard 650 and pay an extra (roughly 3k + trade in $ ) if its a simple change.

i know previously (2016-ish) the restriction was a throttle stop and an ECU loop back plug under the seat, where you would just remove and all is good.

however on this 650L i can only find the throttle stop, no ECU loop back, i did see two plugs going into the chassis under the seat (not sure what this is for)
does anyone know if the ECU needs to be remapped or if there is a simple way to get this de-restricted.

thanks!

Did you figure this out? I just got a 2017 and after ordering exhaust with headers I got an email from the company saying this bike will run lean from the factory. He said the exhaust will make it a little more also, they offered a remapping thru them for $500.00. After cursing with my fingers typing all caps I thought screw, I’m gonna install the exhaust anyway so I might as well figure out if he’s right. I have not messed with anything yet and just doing research. I found you and thought maybe you have figured it out. Not much about this bike out there. The engine seems weaker than other 600/650 bikes, never had a kawa! What I found was the BOOSTER CABLE and others like PAZAZZ OR PAZAAZ. Great reviews and plug n play with maps already there. What do you think? Where is idle screw? Is there a loop plug like 2016 models?
thanks

For deristricting your 2021 z650 you have only to remap your ECU!
The deristricting is avaible from your KAWASAKI-dealer, it cost
in europe near 140 EURO.
So ask your Kawaski-dealer for deristricting to remap the ECU
with the unristricting software for full power, 68,2 HPs.
You have no other chance, also you don´t need to buy
a other bike...

I'm in Australia, and have have the 2020 model. From my understanding there is no ECU restrictions on the Oz models. Only the Torx screw on the throttle plate which physically limits the throttle travel. I took my off (60 second job) and the bike is in full power! Simple.

if you take out the throttle stop in the throttle body it will make it full power that's the only restriction on the Kawasaki's they don't restrict the ecu
Are you positive? I took out the throttle stop and certainly more power mid speed with the full throttle play..I've the same 2022L you have.
Haven't tried max speed again as yet as need to do a trip to test. Was getting around 160km restricted, although didn't hold for long and top speed was likely still slowly creeping. Keeping in mind we're expecting a top speed of 210kmph (130mph) unrestricted.
