Looks like the K60's won't be available for a while in the rear stock size 150/70. Will order a set with the 140/80 for the rear.
Anyone know if this is OK? I can't see how this will make much difference. Tire diameter is about the same and the width is just 10mm smaller.
Cheers!

I would say you would only notice a difference on very hard cornering, may turn in a little faster or slower, depending on the tire profile of what you are replacing. Should work fine.
