Ive been looking everywhere for parts for my 06 ninja 650r. No cages, no 12 bars, no 50+ tooth sprockets. its annoying. So far ive streetfightered my 650r, built my own 12 bar, and bought a -2 front sprocket. But does anyone know where i can get a 50+tooth rear sprocket? and if they dont have any specifically for the 650r, what other bike has the equivalent rear sprocket size? then ill just buy a sprocket that fits that and put it on. any help much appreciated
