On a different note to almost getting squashed, I sent the rear shock of to MCT Suspension. The previous owner, the Off Road Skills Course in Wales, wasn't as particular about the bike as perhaps some of the others on here would be!!
So MCT reckoned the shock looked like it had done about 50k miles, not the 9k that it had actually done.... perhaps the previous hard life in the Welsh hills had something to do with that!!!!...So went for repair and upgrade of spring, with revalve, as I've decided to to keep the bike. At the end of the day, regardless of how it looks, it's still a low mileage, mechanically sound 1200 GS!!
Should be fitted this evening, will report back once I've had it out for a spin.
And as you say, the BM shock is almost £450, with Wilbers a bit more than that. So considering the state off mine, and some additional bits needing replacing as well as the upgrade, £270 isn't that bad!!
