Vintage relic whose basic engine ended up in the 850 Commando (think about it!), with a rigid frame updated to plunger and then swinging arm, but not much use even in its final form, other than for laid back riding. Lowly tuned motor doesn’t vibrate too harshly and only suffers poor rocker gear wear and gearbox problems. Expect oil leaks from the chaincase. Mostly stuff for collectors, few practical hacks available.
