Another vote for Lyndalls. I changed to Lyndalls when I put chrome wheels on my '07 Fat Boy. Very little dust, no noise, good stopping power. I'll be putting them on my Electra Glide when the time comes to replace the stock pads.
Well, I had noise for about 3000 miles, but the no dust issue made it all worth it with Lyndalls. Lyndalls will be my first mod when I get my new bike.
I went with Lyndall Z+ on the Sportster and also used them on my 04 Heritage .. Great Improvement especially keeping dust off the Heritage Spoke wheels ... Better Stopping Power as well .. Highly Recommend them ..
