Beginner motorcycle – Kawa ER-5 or Suzuki GS 500

Hello I would have a stupid question (will be quite long): Sorry for spelling mistakes, is for me foreign language.. So I’m thinking about buying me a motorcycle as a toy for weekends, etc. I can ride some motorbikes (=don’t fall on my nose immediately), but I’m a total beginner. So I understand of course so much of motorcycles, like e.g. airplanes – I like those things, also want one, but that was it. From the optics I like it too. I would like to buy a new one. Now I have found two types that I liked from the look, are cheap, and I would (I think) be enough: a) Suzuki GS500 b) Kawasaki ER-5 The things cost a bit more than 4,000,- Euro, and have open 50 HP The Kawasaki is water cooled, Suzuki also offers a disc brake at the back, and probably a better frame. So I really have no idea – what do you think?
