I got interesting in this when someone wanted parst for on clist. I m guessing if theres less the 100 left in the usa/ canada. The Triumph Tigress, also sold as the BSA Sunbeam, was scooter designed to have good performance and handling motorcycle. The 250cc model had a cruising speed of 55-60 m.p.h. ( top 70) and petrol consumption of 120 m.p.g. Non CVT tranny. I ll never see one in person but it's interesting that they could make a 250 cc engine 40 years ago that got 120 mpg . It's got almost the same speed as a helix. To bad they aren't making something like it now.
