If you don't take a pillion, exhaust hangers are a great way to finish off, and replace, the rear foot pegs. It doesn't look good to only remove one foot peg and leave the other because you need it to mount the exhaust. Exhaust hangers completely replace the foot peg and give you a strong, stylish place to mount the exhaust. You can also get a kit (not all bikes are available) that included a footrest blanking plate for the opposite side to cover up the bolt holes left when the foot peg is removed.
 
This stylish R&G Exhaust Hanger has been specifically designed for the BMW  F900GS(A) 24- / F750GS / F850GS / F850GSA (Akrapovic fitment only) and not only reduces weight, but also gives the bike a sportier, sleeker look.  With a classy, black, powder coated finish and R&G graphic, it is made from sturdy, aircraft-grade aluminium and will retain its good looks for many years.
