I am looking at getting a bigger bike, since my girlfriend wants my GZ 250. I have read comments where the LS 650 struggles to do 75mph, which makes the bike sound pretty weak, my GZ 250 will get up to 65mph on the flat pretty well with my big butt on it. I don't need to do 140mph (or any other high speed...), but I would like a bike that will pull uphill without too much effort. My other bike I am considering is the Vulcan 500 LTD, which I read has no problems in the power department, putting out 50 hp to the Savage's 34 hp.
