468041 Starter ring conversion kit. 102T to 66T

The Spyke starter ring conversion kit is designed to upgrade 1998 to 2006 Big Twin models, excluding the 2006 Dyna, from a 102-tooth to a 66-tooth configuration. This kit includes the necessary starter gear and ring gear to complete the swap. By reverting to the earlier 66-tooth design, your starting system gains the strength needed to handle high-compression or large-displacement engines that often chew through standard 102-tooth gears. It is fully compatible with the Spyke range of starter motors and provides a much more reliable engagement for high-performance applications. This is a proven solution for riders who want to ensure their high-torque starter has the mechanical advantage it needs to turn over a heavy-duty motor. This is sold as a kit.
