No doubt it - all about attitude. Further, whether you like it or not, sometimes 'cool' takes precedence over function. The basic design is similar to the telescoping / hydraulic forks on a modern bike. Opposing springs using frictional drag instead of hydraulic drag. On well designed aftermarket springers the right neck height, proper rake and trail the bike rides and handles reasonably well. No different than if the same setup is used but where the long FE is telescoping.

Does it make sense? Of course not. Is it safe? It is if it's well designed, tuned and sprung properly....................... but only up to a certain point. No different than taking a drag race car canyon carving.

It is a tribute to a traditional style of motorcycling.
