New CBF600 handlebar

Hi, I bought myself a Honda CBF 600 just under a year ago. Yesterday I was split to the fatality, and I left myself. Thanks to protective clothing, nothing happened to me, but the motorcycle The handlebar is bent and the switch. With the switch I get it, the change I myself, but with the handlebar I am not sure. I find the original not very nice, therefore the question. Which other handlebars fit without having to change the trains, which can you recommend (fahrko mfort and handling) and how strongly does this affect the feeling of driving? I will probably have it assembled, or do you think that I can do this myself as an unskilled kfz mechanic? Do I have to register this with the TÜV?
