-- yes...definitely suitable, and i'm in the north east...they are grippy when cool...but again, street riding....which is certainly not demanding immediately - i have been using michelins on the street (power-1's) for a while now, and they have been the most fun i have ever had....milage was "not the greatest" (at 1500 miles a set) but the trade off in fun factor for me was by no means an issue...i really enjoyed them that much to not care (changing them myself does make a difference as well)
-- the cups on the other hand, now have increased durability (2500 miles) 2CT (dual Compound Technology in Michelin speak) - with a B compound rear (there is a choice between A, B, or C rears - A = softest/qualifier tire), and A compound front, i think if you just want the feel of grip/grip/grip you will not be disappointed....your push/shove at the bars will be a tad heavier than the stock pirelli but again.....grip/grip/grip is the buzz word for the cups -- keep in mind that a 190 cup rear will measure the same as a 200 pirelli that came on the bike stock - the front cup (i didn't measure) but the profile is more rounded than the pirelli, certainly another factor in why the feel at the bars is a tad heavier
-- while track use would warrant low pressures, in the 24/26/28psi range, i've been at 32 front 32 rear, and find it works - going up or down a few psi isn't bad, but for me, the overall balance of my weight 205lbs, bumps/pot holes/tire grip balance out well with 32/32
-- michelin also introduced last year a replacement for the street version of the power-1, called Power SuperSport 2CT+ (dual compound track day tire) - the + indicates that the more durable center compound extends under the softer shoulder compound with the intended outcome to be increased cornering stability especially under acceleration with a more durable center (for increased milage) - i just mounted these on a smaller bike, but have not had a full season with them (let alone a first ride)
