My OE shock got to that stage before 20,000Km! The bike would barely stay on the side stand the shock was so saggy.

You can get them rebuilt, but in all honesty the Sachs item is/was a poor shock even new and factory fresh. Not really worth rebuilding unless your budget is really tight. You'd probably be better off finding a little extra money and investing in a good quality, proper, fully adjustable shock which is properly sprung and set up for your weight/loading/riding style.

Why not support your local industry in the Netherlands and get yourself a Hyperpro or Yacugar? They really aren't going to be more than EUR100 more than a fresh spring and rebuild of the OE shock. There are a fair few other options out there in prices to suit all budgets - Wilbers, Ohlins, Nitron etc. All better than a rebuilt Sachs!
