R1100GS Wheel Sizes

[Chrizm]

What size wheels should my bike have? I have seen specs online that says it should be a 17" rear with a 19" front but the tyre on the front is a B020 and is a 18"? Is this normal?

It dont bother me that much but just wondered why thats all.

should be a 19" on the front, someone's put an 18" on to help get it turning quicker

Does the 18 inch (fnarr fnarr) front wheel have spokes?

yep front is a GS wheel, its the tyre size says 18"

Its probably off an R 1100r you can get some of those with wire wheels - the classic model as I remember.

But I wonder why? Does it have an advantage? Suppose the speedo will be out also?

Not excessively if it uses the 1100's one.

But using the 1100R's drive on the 1100 makes the % error much less, so if your wheel & bike has the correct one for the wheel size it'll be about 9.99% over reading, IIRC.
