I'm sure the Rizomas are nice but.. they are even pricier than stockers. The only reason I'm not rebuying stock signals is because it's $200 for a set of four!
I see what you are saying by buying 2 pairs.
I didnt mentioned I run an intergrated tail light no turn signals out in the back so i only bought a pair. I replaced the tailight with the street triple unit and got rid of the crappy mad doctor. best of luck on your search ... i am sure there will be plenty of options from everyones input on this thread
