I put Centramatic on board balancers on my 2009 Ultra. This is without question the best thing I have ever put on a bike in my 45 years of riding. The improvement in stability and handling was apparent the first ride I took on my favorite local twisty road, it was like the bike was on rails. I then took it out on the freeway and set the cruise control on 70. No Harley I have ever ridden has tracked this well. How many products do you put on a bike that pay you back? The company claims 35-50% increase in tire wear. Can't wait to see that!
