I've got nearly 15k miles on a Ninja 300, I know that mill pretty well.

I will say that exhaust is utter dogshit, and it traps a lot of moisture under that heatshield which is particularly annoying for the midpipe clamp, which corrodes fast. There's a lot of aftermarket solutions, though, most are stainless.

300 is not known for great fueling below 6k, I'm guessing they've tuned this bike accordingly as I had to get a fuel controller to sort mine out.

I think 39HP is very optimistic, although I do note those header pipes look a lot less restrictive than the Ninja 300. Conventional wisdom says that an aftermarket exhaust system and tune on the 300 is worth about 5-7hp.
