How do you change a clutch cable for an aprilia rs 125?
No,wind off the adjuster on the lever that you pull.Then pull the nipple and cable out.Loosen the adjuster at the engine and do the same(it may be a good idea to photograph exactly where the cable feeds down).Once you have disconnected at both ends,you can now feed the whole cable out.Refitting is the reverse,but make sure it doesn't snag or kink anywhere and the bars turn freely without affecting operation of the clutch.Once fitted you should adjust to give 2-4mm free play on the lever.
