Threaded bar ends kit (with or without 5/8-11 UNC tap)Description These are typically purchased as an add on to C3 FORCEFIELD NXT Handguards, but can be used in many applications. C3 Centerflow heated bars have bar ends built in. If you're running stock handlebars, you need an M8 thread mount in your bar ends to mount C3 FORCEFIELD NXT Handguards or any other wrap around guards. We were tired of tricky and unreliable friction style mounts from other brands, so we've designed rock solid threaded bar ends.
