Geometry Question...new math??

[Decreasing_Dave]

I have an R6 and I've been running Dunlops (dumb-wops).  The size, 120/70/17.

The question, What will I have to do to my forks (adjust) to equal the same geometry with the Michelins??

TIA

You mean you have to change things on your bike for that???   I'm screwed.

I make it a point to never change anything and so far it has worked pretty well.  I would suggest taking measurements and determining which direction to go based on them before swapping but don't make the actual change until you have tried it.  I put the 190/55 rear on my RC51 and knew that the extra inch of height in the back would require a change.  After riding it I decided I liked it better than before and left it with the old settings on the new tires.

We normally drop 6-8 mm on the front by sliding the tubes upward through the triples to compensate for the 70 series front.
