For me there is a problem, I have to get my bike up an alleyway at the side of my house with the mirrors folded in and then I have only a couple of centimetres to spare from the ends of the brake levers touching the walls, so while I am pushing the bike on my toes I inevitably every so often scrape the levers on the wall and the brake comes on. There's also an iron gate at the end which does not open fully due to the curved roof and so I have to steer the bars through one at a time so as not to get the levers caught on the gate.
I've already fitted the slim KTM bar ends but shorty levers would make my life a hell of a lot easier.
Then if only I could get some decent looking flip up mirrors (That aren't as much as the Rizoma) so that I don't have to have a spanner in my pocket to tighten up the right hand one all the time, I mean whose idea was it to have two left hand threads anyway, makes much more sense to have one left one right so neither of your mirrors fold in over 100mph (if I don't tighten with the spanner anyway).
