It is an ECU restriction, as soon as i get the A license (unrestricted) a Kawasaki Dealer can delete this restriction easily.
Yes it is the same 35 kW. I dont want the headers to get me a lot more hp, i just want the epic blue titanium look and maybe a little bit more sound. I dont plan to do it while in possession of the A2 license, because, as you said, there are going to be a lot of struggles because of the changed power output.
Also, top speed isnt the thing i am going for in a motorcycle and i am totally with the power i have now and i am just excited to get the normal power output when deleting the restrictions
