These are the best mirrors for this platform......so far. Good function vs style with less vibration. Stock mirrors were shyte to begin with and with the extensions just become a longer vibrating can't see mess. To a certain extent, I have observed Italian Duc riders in Italy don't really put much importance on looking behind them when they ride, always leading the parade at too fast a clip on narrow 2 way roads. I would imagine the road carnage in Italy is somewhat staggering.
nowt wrong with those cheapo ones if fitted. no problems with the vibrations on mine and can now see ok ish behind me! and can't beat the price. thanks to @d8mok
