YBR 125 front sprocket question

Hi, I'm new but I've used the search function and cannot find a solid answer. I have a brand new YBR (injection) and have enjoyed the bike. My commutes on a 70mph road (A2).

I've read about some sprocket info such as 1T on front is roughly 3T on back etc. What I am after is if anyone has done a extra tooth on the front. I am familiar with gear ratios so I understand acceleration will go down if I increase the front by 1T which isn't a concern as wider gears would be nicer for cruising and I imagine the wider 5th will drop you more into the powerband when doing 60/70 to aid the bike. So really I'm looking for someone that's done this on the following bike or similar and too see results if its worthwhile.

Any help/advice/input is appreciated
