Hello. First of all, I would like to apologize in advance for typing errors. German language is just a heavy language )) And now briefly to my question. At 17 years I got an aprilia rs 50. I drove the good piece about 2 years. Even with the few hp and narrow rear tires were slanting and Willys no problem. So. I am now 28 and since that no longer driven. Last year in late summer my A driver’s license made. First on ne 600 he ridden ) (er6 n). My first impression. A lot of bangs But that was really the first one after half an hour driving the thing was already too lam to me. I also have to say that I had a very cool driving instructor. 160 170 on. Highway always drove without being noticed. Now it’s the summer coming and wants to get a kilo. Ne k4 or a cbr. Well I have respect for so much performance but when I buy a 600 he is afraid that will be too little performance. also family father and I don’t want to kill myself. And at the end I want to add that I’m a test driver by profession but of course in the car area and therefore maybe also this respect for so much performance. What should I do. Willys I want to do with the new motorcycle of course and also sporty driving. But do not want to kill me by any means ) Ask for advice and apologize again for the spelling and half the bible )) Thank you in advance
