Mr Pink

Hi ,,I have a 1999 R1 and the Rear shock is now leaking and needs replacing £££££ ...what are my options ??? was looking at Ohlins ..However £750 is right out of my price range ... I really do need need a top Spec all singing and dancing Model ....I would rather not buy a stock replacement from Yamaha ,when there is much better shocks out there for a little bit more money Thanks Andy
