I was thinking of getting one of these as I had an indicator on my 125 and found it useful when I was learning. However, 1st or 2nd I get pops from the exhaust on over-run, 6th at 5k rpm is 60mph and anything in between doesn't really matter as long as it's appropriate for the speed I'm doing. Having ridden for almost three months without one and not missing it, I decided not to bother getting one.
