ok, i've pretty much decided on either the ninja 650r suzuki sv 650s or ninja 500. pretty much it all is gonna depend on pricing and location for me. is there anything imparticular i should look for since i am going to be buying it used. are there any areas on theses bikes that i should specifically look for? i don't want to buy it and just look it over give it a quick test ride than find out something is messed up because i didn't look close enough and know what to look for. thnx for the help.
