ookay I will try to tackle this...

so.. are you looking @ slics?

The zx6rs are among the few bikes (if not the only bikes) which come stock with a 65 profile tire on the front. there are very few high performance tires that are made in the 65 profile for the front... why not just put on the 60s? this will lower the front a bit more, and will give you a wider variety of tires to choose from. However I would only go to a smaller profile if I am tracking my bike... If I ride street with the uneven surfaces we find I like to play it safe and either stay at the stock, or go up to the 70 profile (another more standard size)

this is with the front.. as you said you can take the rear and raise it to the next profile size. Again that would change the geometry slightly so that you would have an easier turn in... your loginc makes sense to me but then again I am not a tire expert.

Ervins:

you are talking about making your profile lower? (your tire wall?) If this on the back it will change the geometry slightly to give you a harder turn in.. and also at a 50 profile tire the wall is tiny and I know the roads you ride on! you are increasing the likelyhood of messing up a rim from a bump (but this is just me trying to play it safe)...

While your logic contradicts that of the person above you. You are both right... the beheaibour is there. however raising the back, (or lowering the front) can be a bit more noticeable than changing withs.
