Great product! Vibes above 5000 RPM on the Tiger were terrible. Added the Evotech bar end weights and it's like a different motorcycle. Reduced the vibes by about 75%. Much better for long distance touring and revs all way to red line without making it feel like the bars are going to vibrate out of my hands. Best mod I've made to the bike!
The only thing I'd change are the instructions. They're slightly off, but otherwise installation was very easy.
