Be prepared to spend some dough at twisted throttle. I looked at the luggage racks for my SV650 and was shocked at the price tag. I wish someone here with some metal fab/welding skills would make a simple luggage rack for the SV.
I figure they could be sold all day long for no more than $100. Motorcycle accessories are way overpriced. I understand supply and demand, but c'mon. Givi stuff is a perfect example. It costs almost $1000 bucks for a top case and two side cases with mounts. Dang, they are plastic afterall. I can't believe people pay those prices.
Good luck. I just mounted my tailbag to my passenger seat and said to heck with the luggage rack. It's a little different getting on and off the bike without hanging your foot on the bag, but you get used to it. I would still buy a luggage rack (not the cheesy suzuki rack) in a minute at the $100 price point.
