Reckon you’d be best off getting it serviced especially if you don’t know when last done. Shouldn’t cost much more then £250 without a spring change.
It's probably never been touched since it left Ohlin's factory. Yeah, I've found a place in Cork who are Ohlin's factory trained suspension guys so I plan to take it there over the winter, get it fully serviced and have the suspension on the bike set up professionally by them rather than me doing it - although my attempts to date on other bikes haven't been too bad, at least a noticeable improvement over how they were.
Yes. I had mine done a few years ago. Unless you like the originality of the plated steel it’s a no brainier as it’ll be striped down for a service anyway. Or it should be !-) I’ll see if I can find the pics of mine. Not the best quality photo. But the body comes as a sort of grey anodised finish.
