I put a 65 on recently. It was more of a change than I expected. Going from a worn out 60 to a new 65 is about 1/2" higher.
I like that it fixes the speedo and odo. But, I don't like sitting up higher. I'll go back to a 60 next time.

Just digressing a little, but there were several comments about the change of tire correcting the speedometer accuracy. I find that very interesting. On my 2002 GL1800 (and my earlier 1999 Valk) with OEM size tires the speedometer was always about 5mph faster than actual speed at highway speeds. I would compare it with GPS true speed and we would always talk about Honda speeds vs actual!
However, with my 2016 F6B with OEM sized tires (Bridgestones and Dunlop E4s) my speedometer is VERY accurate to the true GPS speed.

After 8K on OEM Tires and 7,600 on E4’s I tried the Michelin Commanders. Speedo was off slightly with first two but with the Michelin’s it was dead on. I put 6k on the Michelin’s before I traded my 13 F6B in and they looked almost new. Michelin’s seem to Handle better and it set slightly higher in the rear. Only trade off or negative I found was that there were bias ply tires. Gave up some plushness in the ride.
