Can't disagree with that Ferret.
I wish a time consumption monitor was included on modern bikes. It would be so easy to do with with modern instrumentation. Maybe a bike has low mileage, but has spent most of its life idling in L.A. traffic. That might be useful to know.

GO, a bike doesn't spend much time idling in L.A. traffic...
but a car certainly does.

What was I thinking?

The issue here is whether the profile of the OEM 140/70 and the 160/60 result in different diameters. As I recall, they don’t so there should be no speedo variation other than that you describe.
Yep, I get what you are saying, like for like there should be very little difference in the aspect ratio, 2mm is the only difference there, minimal impact.
60% of 160 = 96 and 70% of 140 = 98

At the risk of sounding like a mechanical idiot, I was curious how the odometer calculates mileage. In other words, is it based on tire revolutions (i.e. diameter) or does it work off engine revolutions? Just wondering if a different tire size could potentially cause miles to accumulate faster or slower as a result of non-OEM tire sizes.
On the older bikes, like my Daytona, it is taken off a mechanical drive on the end of the front wheel axle. One newer bikes it is often electrically taken off a sensor from a rotating shaft in the gearbox. Changing the tyre would affect both though. Image the tread wearing 5mm, that is an overall decrease in diameter of 1cm. With simplistic maths and assuming the tyre profile is perfect, a complete revolution of the tyre new vs old would present a difference in distance of just under 4.4%. The Odometer didn't know you changed your tyre. So for the same engine revs you actually end up travelling slower as your tyre wears.

Some what related . Yesterday I put new Michelin 245/60 18 tires on the back of my 2017 Honda CRV , the OEM tire is a 235/60 18. After a few miles the TPMS came on and I could not switch it of. Went back to Discount Tires and also put the 245/60 on the front and all is fine. The fronts were not worn at all but Discount Tires gave me a REALLY great deal on the new ones , they could sell the used ones they told me.

Ha never noticed this before. Just the way the tire rolled in when I parked it, looked down and saw my rear Angel GT has "GT" carved into it. Pretty cool eh?

Cool yes, but disappears pretty quick.

I imagine, but never saw it at all on my first set.

It would have been there.

Really, I know time is money (and writing takes time), but sometimes you sound like the oracle of Delphy
