Hi everyone, looking to raise my handlebars up, and fit a good set of aftermarket bars. Thinking about ordering a set of Rox Risers: http://www.roxspeedfx.com/cgi-bin/cart/showitems.cgi?subcat_id=268 5inch rise. The risers bolt into the handlebar clamps. Question One: What is the diameter of the standard bars on the bike now ? Question Two: What diameter are most after market bars ? Renthal, or Pro Taper ? Do I go: 5" Rise x 7/8" Stem Clamp x 7/8" ? OR Do I go: 5" Rise x 7/8" Stem Clamp x 1 1/8" ? Any help, as usual, is really appreciated.
