After buying a used ZZ-R 1100 I have had after short trips regularly numb fingers. I thought it was necessary, on the inclination of the handlebar (Superbikelenker) until it suddenly vibrated so right in his left hand. Because one thing was blown away with the handlebar weights acquired during the journey - it's hopefully not landed somewhere damaging. Looking for new handlebar weights, I came across this one because they fit the description of her at exactly the handlebar. The installation is very simple, only the throttle it was to watch that he does not drag on weight and turns freely. At the first exit after the installation I could not believe it. My fingers no longer fall asleep! I've tried it, even after an hour Autobahnhatz no snoring coming from the hands. And honestly - it is also felt when I so think of the feeling with the old weights. Small cause - big effect. And they also still see great, coincidentally my disguise color. Thumbs up!
