The Yoshimura Heat Shield is the replacement shield for RS-4 2-Up mufflers — the configuration built for bikes that carry a passenger.
A heat shield matters more on a two-up machine than on a solo one. A pillion's leg sits closer to the canister and has nowhere else to go, and the shield is the only thing between a bare calf and a muffler running at several hundred degrees. It is also the first component to get scuffed, dented or lost, because it sits on the outside of everything.
This is a direct replacement for the shield supplied with the muffler, using the same mounting points.
Fits Yoshimura RS-4 2-Up mufflers. Heat shields are specific to the canister and the application — confirm yours before ordering.
