Our customers continually ask our opinion when it comes to performance accessories for their motorcycles. Our experience from countless test runs with many different combinations of parts has led us to recommending a select few over and over again. Before we will recommend a part or accessory, though, we first try it out on our own motorcycle, or we do multiple test runs with our customers who are currently using a selected performance item, and gather their experience, opinions, etc.
So, we now present a list of "Rolling Thunder Dyno approved" Performance Sources. We recommend these accessories and services because we have experience with them first-hand, and we know that they work.
