aye, been all over your site pal.
Givi bars are the most popular. I got Givi's because they protect the top of the bike a bit more (but fit them right, or you'll be driven mental by a wierd rattle after a while, contact me or read another post in the gallery bit from earlier today.
If you're getting a bashplate as well, there are a few to go for. Forget about any one that has a hole to drain the oil without removing the bashplate, because 1. Where there's a hole there's room for the bike to get a smack, and 2. I defy anybody to remove the oil drain bolt and magically drain oil through another hole below it, and 3. How the fk you going to get the oil filter off. (And even if you don't do this sort of thing yourself, you want to get used to taking it off and on so you ain't paying a mechanic labour to undo some bolts. I got one from a bloke in the USA , narcosis junkie, because it was the most substantial one I could find, and it has had a hammering, with no ill effects, and I mean a real battering, 2 up offroad etc. The swmotech one has been upgraded lately, might be worth a look, and the best one I ever came across really is by some australian blokes, B & B or something like that.
Get crash bars on as soon as you can though, they are a piece of cake to fit, really , very easy indeed, and you'll be gutted if the bike goes over in some gravel or falls off the sidestand while you ponder the crashbar options.
Also if you're noticing a bit of a buffeting or whatever, move your screen up (again, dead easy), and stick a few washers in the bottom 2 bolt mounts, to tilt it a wee bit (or buy a madstad if you are loaded)
Also, change your mirrors to aprilia ones (loads of posts about that) and/or get mirror extenders. Not only will you see more behind you, including your good lady's grin, but you'll reduce the buffeting a bit.
Cheapest option to reduce buffeting though I reckon is to lift your visor. I canny remember the last time I had my visor down, although I use a wee inner sunshade visor a lot.
There ye go!
