My concern with this list is that with a single exception, all of these motorcycles have been "discovered" by collectors. The CB350 Honda is ubiquitous and generally unloved, I'd hardly consider it a candidate for future love. What I would add are purebred competition machines. Similar to race cars, these will always be valued as pinnacle examples of their era. Air cooled Yamahas, the TAs and TDs, for example. Honda's equivalent RS series as well. Also, lesser known but very successful racers like Bultaco's TSS grand prix bikes. In the lower price ranges, but rapidly gaining in value are European motocross motorcycles; Maico, Husqvarna, and the Spanish brands, etc. Most of these are priced below British examples of the same, like BSA Gold Stars, etc., yet are more rare and generally have great histories. All the requirements for future positive valuations.
