Thanks - takes me back to when I was a kid, mid/late 1970's, helping out with the Beamish (north of england open air museum, nothing to do with stout) reliability runs. Flat-tank triumphs, antiques with leather belt drive, modern stuff like Ariel square fours and saddle-tank Nortons...
120+ miles around the Yorkshire dales, including some off-road sections that I'd think hard about tackling on the GS. And the Morgan three wheelers used to go up them. I used to ask the highway code questions at the lunch stop in Stanhope: what does a "give way" sign mean seemed to be the hardest part of the challenge for some....
There was a similar car event: memories of a two-speed Frazer-Nash going sideways up yorkshire hairpins (solid back axle, twin chain drive to different size sprockets, sliding dog clutch at the front to engage one or other front sprocket and so drive the high or low gear chain - it had no other choice).
All just before the machinery became cherished classics, so the old and foolish (or, as I see it, enthusiastic) could still use it as its makers intended. Don't suppose it still goes on today?
Didn't really know what I was looking at in those days, but at least I saw it and have some hazy memories. Like Steptoe, I like to see the patina of age, use and ex-owners rather than a pristine restoration.
I wonder if the Ariel square four is still pulling a sidecar full of lobster pots up the steep climb at Robin Hood's Bay?
Ah, memories. But no photos I'm afraid. I was young, diligent, and had highway code questions to ask.
