How will it sacrifice your top end??? "more distance per revolution" You will gain top end(at least down hill until rev limit kicks in) with a taller tire period.(real speed GPS(not speedo))
Dass we documented this at the time I put on large tires on in a controlled downhill stretch with stock tires, then oversized tires, then 12g rollers... and finally 13g rollers.
I don't pretend to know or understand the physics and theories but I do understand the actual results of the carefully executed events of last falls modifications. They are as follows on the 2015 Honda PCX;
1. Stock 2015 PCX benchmarked on a select section of highway grade resulted in 64-65 mph before limiter.
2. Michelin 120 front and 140 rear tires were installed and benchmark test run on the same grade resulted in 4-5 mph loss in top speed using a GPS.
3. NCY pulley and drive face was installed...

un-impressive results on the same downhill bench run. Noticeable acceleration loss as well.

These are real world results you can take to the bank, been there, done that... no speculation. Others with NCY pulley/13g rollers on stock IRC tires have topped out even faster and can leave me in the dust.
Conclusion; big tires equal slower PCX but you can recover nicely with NCY kits and that's why I claim 4-5 mph faster than stock after all is said and done. The loss in
mpg is a different story and I still don't have those numbers but will give that soon if it will stop SNOWING!
You take Care now!!
Take good care of yourself.
anything but cancer works for me. I think Jesus wants to talk to me about something anyway... not really looking forward to THAT!
rather "do you want to live forever?" is more common, I do get that one.
Done!
