Review: Top quality - Installed this on my 1975 Sportster and it is better than I ever imagined. Easy to install and functions excellently. Very high quality
Review: 4.5 stars easy to install - Excellent feel even on bumpy dirt roads PRO maintains a steady speed. Easy to install can be done at home..w proper tools need to trim a few inches off handle bar Excellent craftsmanship.... CONS The alum adapter sleeve has the WORLDS smallest set screw..useless the sleeve is so thin they cant use a bigger set screw...i found using left side grip works perfectly save the $25.00 and buy a leftside grip...am doing a full review and install set on facebook page
