here in lynn, MA, where there is a strong pressence of hell's angles, there are lots of bikes with bars that are shoulder height and even one guy whose bars are over his head. if low bars are dangerous, than high bars must be really safe. it might be easier to put a small low gas tank on your bike for inspection purposes and swap back to your prefered tank than to do the control swap thing. I can't stand the position (or the look for that matter) of the stock bars which came on most sixties and seventies bikes and have clubmans on all my street bikes. bar to tank nerfing is a real bad thing, avoidable at all costs. loss of (a little) steering lock is an easy mod. usually.
