yeah i hear you man. i downright talk crap to my friends everytime i see um drinkin the stuff.Their logo looks good but if their that anal about people wanting to give them free advertisement I wouldent want their logo on my bike. I wont drink that stuff for the same reason. Bad customer relations if ya ask me.:headshake
there's loads and I really do mean loads of riders over here that have red bull decals on their bikes, they're starting to look dull because you see them that often. you can still find sets on ebay and some graphic shops still sell them eventhough they're not allowed. haven't heard about anyone being persecuted for riding red bull logo's though, red bull might prohibit reproduction of their graphics but it's not like their gonne come after everyone that does sell them...Red Bull graphics are not allowed by Red Bull. Red Bull will actively go after anyone making Red Bull decals. I think they even go after web forum sites that let people advertise that you can get them. They are a little overprotective of their brand. I know www.ktmtalk.com has a sticky that will ban anyone trying to advertise or sell Red Bull decals (probably warned by Red Bull themselves).
I have seen them for RFS based bikes though, but not at all on a 625. I still have never run across them. I would think eBay would be your best bet.
