Barry,
you know that anyone that gives an opinion of tires is opening themselve up to a bashing of different opinions.........
my $.02 comes with a disclaimer!! "it's my Opinion" and i don't car what others "feel" about that.
stock brickstones were junk and dangerous at 4k on both new rsv"s i have had
metzler stock sizes were great and didn't last more than 9k
avon venom stock sizes, sucked from day 1 and came apart at 2600 miles and 5 days after install
michelin comanders in stock size were fantastic to about 14k however they were discontinued
dunlop 404 stock sized were junk at 5500 miles
dunlop e3 in stock size wear great to 17k but not very sticky in the turns
michelin comander 2 in stock rear size and 1 size smaller in front are on the bike now with about 7k+ and they stick in the turns great and seam to be wearing great, however the smaller front tire makes the front end much lighter and quicker to reactions and road conditions and a bit too quick at times.
there is my thoughts.
