because it doesnt make any sense.
the bike is designed to run on 95octane which is what i use, maybe it may run a bit better with 97 but it still should not knock very loudly using 95.
the aprilia has a high compression also and wouldnt knock at all.
this is not a faint tap sound, its a loud knock like a big end is gone.
its going back to the honda dealership and im going back to a s1000xr.
thank you to the people who have tried to help.

Sorry your CT experience has fallen short, would appear you were unfortunate enough to end up with a “bad”bike.

Hope you have more luck with the BM.

I have just been to a motorbike mechanics shop and he went for a good long test ride and said the bike is mechanically perfect, he says the noise I am hearing is airbox roar.
So I'm pleased at that !
Strange low loud it is though and that I've never heard air box roar on any of my other bikes.
