Only thing you gain with 180 is better choice of compounds with some tire brands.
Pirelli 180 works fine on F3 rim but their 160 tire is also good.
It is better to stay with 160 if you can, there is also nothing wrong with using 180. I have done same times with both tires.

I would put my $$ on F3 wheel. From spokes out it is lighter and 160 tires is lighter than 180.

The difference in weigh between Honda CBR600 F3 and the 08-09 GSXR600/750 is about 4 lbs ...And the Bandit GSF1200S is almost 5 lbs...

We are not talking about mass weight, we have that.

Need to find someone who has broken wheel so can chop spokes out and weigh rim!

I bet they are close. Assume they are same :)
I would be interested just to see tire weight difference on rotational assuming there is .5kg difference.

Lighter tyre being 3kg sound reasonable?

No. .5kg is resonable difference between same brand/model tires in 160 vs 180 size.

Assuming radius is same I will have some numbers soon.
(it is not far off if you are comparing 160/60 and 180/55, assuming numbers on sidewall are true)

To get idea front tires are around 4.5kg and rear around 5.5kg
