I have the american "HeliBars" on my new 'bird. I like them. Haven't tried this German "Superbike Lenker" (that's what it's called I gather), but it does look ugly.
The HeliBars make all the difference to me - I got backache with the originals, now it's bearable. I liked them so much that when I traded my old carbed 'bird in, I kept the 'bars. Tried using the bike without for a while, but backache came back... so they went onto my 03 model redbird as well. Expensive, though!
Happy riding, high or low!
Udo.
