pretty much anything other than stock on the 06/07s looked good. the dual akro's still looked a little bulky to me still but it was ok. the r1 is the only one to ever get the undertail look right, all the aftermarket ones don't look as good as the stock ones.

if someone could get the r1 clean undertail look and the good heat shelding of the 10, all in one bike. that would be right... but seems like no one can ever build a bike and get everything right.
