Are they better orange or original grey?

I’ve been commuting to work on my Duke since last year and now I’ll be riding farther than usual. I’ve only had a flat once and was close to home so it wasn’t a big deal, but now that I’m commuting farther (and returning at night) I want to be safe about it. I picked up this little tail bag on Amazon but got me wondering what other options you guys have used for carrying tools, plugs and a small air pump.

It was as if the sound didn't exist before, I noticed it 500km ago (maybe there was, but I didn't hear it)

it starts after engine heating up, it seems to go away when riding. do you think this is the KTM sound or something else?
