Lightech Chain Adjusters Aprilia RSV4/ Tuono 2009-02014

LighTech Chain Adjusters allow for quick and precise chain adjustments that makes chain adjustments a snap. Rather than guessing the axle’s position, micro measurements are now clearly shown on the laser-etched chain adjuster body. When you make an adjustment, there is a distinctive click from the adjusters. It's as simple as "3 clicks back on left side, 3 clicks back on right side" and off you go.
