That bit that you sit/ perch/squat on is pretty important, I’m sure you’ll agree. In the few years that I’ve been fixing up a few old Ducatis I’ve taken a few different tracks to ensure I had a pleasant place to sit.
This is bearing in mind that A) I’m a short arse, about five foot eight on a good day and B) fairly light, around 11 stone (low 70s on the kilogram scale.) I’ve frequently gone for a fibre-glass base, courtesy of Lord Ken of Halliwell, which would then be padded and trimmed to suit. The riding position provided by this arrangement is a bit cramped for anyone of a slightly more robust stature, but suits me fine.
Back in the day,
