Another middle aged man suffering with "collection obsession disorder" here saying Hello!
Time to buy a new toy off the wish list to add to the land rovers, hondas, etc etc..... but still convincing myself that I'm too young for the Harley chopper just yet.
Anyway as a member of many "specialist vehivle" forums I learnt a long time ago that not only is the knowledge gained second to none but also that it's definitely worth waiting until one of the forum enthusiasts decide to buy a new toy themselves and decide to sell their baby
So apologies for any daft questions about things already covered hundreds of times (I promise I will try to search first) and also for loitering on here hoping somebody sells a well loved tidy S1 or Xb
Northern born and bred but living in the sunny South these days

As an owner of a 'well loved' S1 and and XB12S You have to understand they are two animals. S1's are better looking, more reliable 'once all the recalls are done' heavier and it's top heavy weight, and more ponderous in the handling department. XBs are much smaller in size, harder to service, when it does go wrong in the engine department it can be catastrophic. Have undersized wheel bearings that don't last too long. But on the upside They can be put millimeter perfect into a corner. They are scalpel like in handling,brake better.....You'd better get one of each 
.............. You are evidently are a very sensible chap ............we could certainly do with more like you on this forum - welcome.
