I think I have a spare curvy mirror mr uki could have - believe they does the same shiz. Just trying to recall exactly how the reservoir fits
maybe they are different...could do with someone to confirm.
Pointy wise, I just bought 2 pattern led indicator mirrors for the pointy £30 new so probably isn't worth buying just a stem (although a call to a dealer might not hurt if they're a fiver or something. If not ebay second hand right hand mirror or a pair of aftermarkets seem your best bets.
PS. yes I have done the same, bloody annoying! Although mine was even stupider as I actually thought to myself 'wonder if I can get it off the paddock stand with one hand' shortly before the crash...
