Which brand of tyre are you considering? Check that the smaller section tyre has a suitable load rating for a heavy touring bike. IMHO you are most likely to discover that the lower section gives you a poorer ride, although that is not guaranteed.

please elaborate, I dont think the ABS cares at all about the change in tire size as described by the OP.
With the change in diameter you may have to adjust the speedo as the wheel will spin faster for a given speed you are riding.

ABS is calibrated for the diameter of the stock tires, change in tire size that is smaller/lager will have the ABS thinking there's a problem because the rotation ratio is off. Yes a lower profile tire will give a different ride. When I'm riding a Street Glide with a lower profile than an E glide I can tell the difference. To me it seems "busier" in that you feel more and smaller road imperfections that the higher profile tire sidewall absorbs. Some might say it gives a better feel of the road but I doubt many are riding close to the extremes where that additional road feel would assist in handling.

Absolutely right! I think my mind was (is?) still obsessed with the pulley conversion I am planning, which does require such a readjustment... But the front wheel definitely does not deliver any information to the speedo 🙈
