F700GS Rear Tire size

[grabcon]

My wife's F700GS is going to need tires in the next 2k miles or so. The rear is a factory size 140/80/r17. I have a set of Michelin Anakee Adventure with about 1k miles on them. The front is the same size as what is on her bike now. The back is a 150/70/r17. Can I use this tire as a replacement for the 140/80/r17?

Will it fit the rim properly?
Will it fit in the tire space in the swingarm?
Will it impact the ABS and/or other systems?

The 150 is less than 1/4” wider per side (.4” total). There is plenty of room for that.

The 150 is slightly shorter, smaller diameter, more revolutions per mile, speedo even more optimistic.

Should work fine. Just remember that you will be going slower than the speedo reads.

My wife always rides slower hence the reason for GPS that displays actual speed.

Thanks for the input

Just like almost all of the 32 BMW motorcycles Voni and I have owned.

I am running a 150/70-17 on my F700GS now. I can detect no real difference in handling. Here are the sizes of the two tires:

The speedo on my F7 is the most inaccurate one I’ve ever experienced on a BMW; 5 MPH too optimistic at an indicated 75 MPH. I rely on a GPS as a speedo and haven’t noticed if the indicated speed is more accurate.

Thanks all it looks like I am good to go. Now when I pull the tires I can fix the TPMS.
