Have you ever been to the drag strip and watched the latest/greatest/super-fast sportbike run as slow as molasses? Maybe the rider sucks? Or maybe the rider doesn’t have the correct set-up for drag racing, especially in the clutch department. In preparation for a trip to the strip with Gixzilla, Brock personally demonstrates how an industry trend moving towards ‘ramp-style’ slipper clutches is making a quick trip down the drag strip even more elusive. Naturally, Brock not only cures this issue, but he takes you on a detailed ride while doing it.
