Would it be OK to put a 100/90-19 front tire on a 2010 F650GS instead of a 110/80-19?

I haven't see anything about doing that but it seems like such a small difference that it should be fine.

Just slightly more narrow, right?

A 100 tire is nominally 3.9 inches wide.
A 110 tire is nominally 4.3 inches wide.

The 100/90-19 has a diameter of 26.08 inches
The 110/80-19 has a diameter of 25.9 inches

That is such a small difference that I wouldn't think twice about running that size. For comparison, the F800GS runs a 90/90-21 up front and handles just fine.

Hope that helps,

Eric

I got a similar question. :)

Is it ok to put the fatter 150/70-17 tire from the F800GS on the rear of the F650GS which comes stock with the skinnier 140/80-17?

Absolutely fine. I had the fatter TKC80 on mine quite happily.
