What gap do these usually come with from the factory?

If I remember correctly it was around .028", but it is always best to double check and make sure they are correct for your application.

Correct fitment for a 2015 Triumph Street Triple 675 ?

Yes but some people like them others do not so it's up to you.

Does it fit for suzuki gsxr 1000 2017

I installed it on my 1999 Hayabusa, not sure about the GSXR 1000, I assume it would work, check on youtube and search if others have used it on google search
