AFAIK the only new underbone you can buy in the US is the Symba, but they are rare and I've never seen one on the road. The only underbones I ever see are old Honda Trail 90/110s.
I'm a big fan of the basic underbone design because they're rugged and highly efficient. Over the last 40+ years I've kept at least one old Trail 90 around and have put 5800 miles on the CT90/140 since last March. It takes a pounding on the trails nearly every day and keeps on going.
BTW My daughter has a 1965 Cub with a Lifan 110cc engine and my ex-wife who lives in Thailand has a Yamaha underbone.
