smithac87 Posted October 13, 2007 Posted October 13, 2007 Im am currently in the market for a 520 chain and sprocket set up for a 07 yamaha r6s I am adding 2 teeth in the rear and dropping one in the front which would put my bike at a 520/15/50 set up does anyone have any experiance with this set up and if u do was it worth it! And what brand you think is best!
