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

Mail?....

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


 ;D

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.
