Bi-metal bar end is made of a 6061 alloy together with a 303 stainless steel core to increase the weight of the bar end and reduce arm pump and vibrations while you ride. Engineered for improved vibration damping and rider comfort, these bar ends add mass where it matters to minimize hand and arm fatigue on long rides. Precision-machined construction delivers durability and a refined finish, while a compact design keeps fitment clean and unobtrusive on your handlebars. Designed to install easily in most hollow bars, the included hardware provides a secure, wobble-free fit so you can focus on control and confidence in varied riding conditions. Ideal for riders looking to reduce arm pump, smooth out handlebar feedback, and enhance overall ride quality.
