You'll want to verify specs objectively.

First, speed-rating is combined with max-load and time. So City Grip's 93mph rating is for 551-lbs on rear tyre at 93mph for 1-hr with stable temperature (no increasing rise). With lower load speed can increase. No problems with using them on Ninjette.

Then verify weight claims:

130/80-16 Dunlop K630 rear tyre = 11.73 lbs

120/80-16 City Grip rear tyre = 10.3 lbs
https://www.motorcycleid.com/micheli...313944659.html

Certainly NOT even close to 5-lbs as claimed. And all of that difference comes from downsizing rear tyre from factory 130 to 120 size. Of course narrower tyre with tighter profile radius would have more responsive handling. But you'll loose some max-grip under cornering and have lower lifespan.

BT46 doesn't come in pre-gen size, but has 130/90-16 available with H-speed rating for 130mph. At 16.08 lbs it's more than 4-lbs heavier than factory Dunlop and 5-lbs heavier than the City Grip 120/80 tyre. Wider taller profile would give slower handling than 130/80 size and much slower than City Grip.

If you want to preserve quick & nimble handling, I recommend set of Shinko SR740/741 in factory sizes.
