They are good and sturdy with a stock/ semi stock bike. But once you get into the 175+hp range, they have a hard time taking a good launch. Dont get me wrong though. You can ride around all day with a set of extensions on a Turbo bike and be fine, but one really good hard launch at the drag strip could just tear them apart.
