The Rifle is a fast, sleek bike that deserves a nice idler. This kit replaces the entire idler system—shaft, chain keeper, and all—with high performance upgrades. Choose from the smooth, durable Sport Series with exactingly machined 7075AL cog ($105) or really go for it with a jaw-droppingly beautiful, ultra CNC machined Ti cog and ceramic bearing Elite Series Idler ($165). Both will have you, and your Rifle, purring down the road like never before. All stainless shafting and mounting hardware, easy adjust CNC machined clamp on chain keeper. An upgrade you'll appreciate for a long, long time.
