im selling my alta 22mm rear sway because i need the money right now. this sway bar has been used for about 2 months, approx 4000 miles on them. i believe this sway bar will fit all generations of MC and MCS, But im not quite sure. tho i do know that it will definitely fit the R50 and the R53. brand new, retail price is $220, but on the website the holiday price lists it as $190. im selling my rear sway bar for $160 W/O SHIPPING. this includes the 22mm bar itself and the 2 brackets and bushings that go with it. if you have any questions or if interested please PM me. thanks for looking, -jb
