468040 Starter ring conversion kit. 102T to 66T

This Spyke starter ring conversion kit allows you to switch from the standard 102-tooth setup to a more robust 66-tooth design. Sold as a kit including both the starter gear and the ring gear, this conversion is ideal for high-torque starters and large-displacement or high-compression engines that put extra strain on the primary drive. The earlier 66-tooth design is known for its durability and ability to withstand the rigors of high-performance builds better than the later 102-tooth version. This kit fits 1994 to 1997 Big Twin models and is compatible with all Spyke starter motors. It is a necessary upgrade for riders looking for reliable starting on modified engines and is sold as a set.
