Hi all Caponuts, 27000kms new chain/ sprockets required. After being shocked by my local Aprilla parts dealer I looked for aftermarket sprockets, great difficulty In finding a supplier. Tracked down Adventure Motorcycle Equipment Quality Motorcycle Brake Discs &: Brake Pads - MetalGear MetalGear - Home of Quality Braking Components Esjot brand sprockets at 1/3 the price of genuine. Front/rear $ 88 including freight. Hope this saves you some cash. Recommend telling your Aprilla dealer how much they are scamming us.
