Chrome pullback riser set is 3-1/2 rise with a pullback of 2 and includes chrome caps. Mounting thread pattern is 1/2 x 13. Risers are machined from billet aluminum. Include top clamp halves and 4 screws. These risers will bring the handlebars up 1 over stock and back toward the rider 2 which gives you a much more upright seating position rather than reaching over the gas tank. This reduces back neck and shoulder fatigue due to reaching. Original hoses and cables can be used and may require minor re-routing.
