Racing Bros Scepter 25 cartridge kits for baggers have the same great features as their counterparts for Dyna and FXR models, the only difference being the lack of adjustability because once installed there is no access to the adjusters. The development of these kits took longer than their counterparts because a lot of time went into getting the setup right, out of the box so no adjustment is needed after installation. They provide an excellent ride with lots of feedback and no lack of comfort!
