Mango, as a long-suffering chaser of Brown sidestands, I can tell you with absolute certainty that the R100 stand is too long for the R65. You could cut it, I suppose, but it might be easier (and more profitable) to sell the R100 and get an R65-specific model. Besides, as rare & exquisite as they are, it seems almost sacrilege to defile or mutilate one.
We just so happen to have an R65 (and others) stand dealer right in our midst, check the members' list for "beemerrich", great prices & quick shipping too [smiley=thumbsup.gif]
