Using these AS3 front brake and clutch levers is easy. Just replace your old OEM levers with them as they are direct replacements. When using, make sure to operate them gently at first to get used to their feel. As for maintenance, keep them clean by wiping them with a dry cloth regularly. Avoid using harsh chemicals that could damage the black anodised finish.
