    I'm looking to replace the tires on my '97 7R which I bought used with a
    rear. I'd like to return to the stock 190-50 for the look of the wide rear,
    but I
    don't want to significantly affect the handling of the bike (which I've
    gotten used
    to). I've read the 190 will make the bike feel heavier and turn more
    slowly. Does
    anyone have experience with both tire sizes on the same bike that can
    comment on
    the handling differences? Thanks.

    I've got a '01 ZX12R... not the same bike, but similar characteristics...

    I went from a stock 200/50-17 to a 190/50... (unsprung) weight difference in
    the tires was just over 1 lb... difference on the bike was significant, in
    terms of turning ability and "flickability"... and difference in wear isn't
    much. On the advice of a number of riders with the same bike, I've got a
    180/55 to put on next...

    I think the 200 on my bike was more for marketing bravado... I'll never go
    back to that stock size.

    Never mind the "look" of a rear tire... go for function.

    There's a 30K ZX-7RR in my shop sporting a 190... a 190/50 works better
    than a 180/55 because the 190 is a smaller diameter tire...

    Comparatively speaking a smaller diameter 190/50 will always turn
    quicker than a larger diameter 180/55...

    The reason a 180/55 has a large following is because it gives a rider
    the impression of quicker steering is due the diameters affect on rising
    the back of the bike which steepens rake and decrease trail...

    It's better to go with a 190/50 and adjust the swing arm down to equal
    the 180/55 increase in ride height... then you have the best of both
    worlds... quick steering and extra side wall rubber a 190 affords...
