The bottom of the depreciation cycle has been reached and that's changed things, some for the better. What's amazing is just how long it took, about 15 years longer than average for collector vehicles. The worst thing that ever happened to the bikes was the bottoming-out of values circa 2002-2004. There is no way you'll ever see the vast majority of vintage CT70s & Z50s restored to OEM stock, the pool of existing parts is way too small and expecting that to change, universally, is unrealistic. Certain items will become rare, check out CB750 gauges, for example. That's just supply & demand. So hold onto your restos & vintage survivors as they transition from old bikes into appreciating assets, as supply dwindles. The downside is that as values increase and parts vanish, they will become less practical to ride. Everyone is entitled to his/her opnion, the dividing line (for lack of better wording) is collector vs rider value. You only get one #1 priority.
As for the resto/restomod issue, as PE accurately stated, some of us have closets bursting at the seams with "Been There, Done That" T-shirts. Everything has its limits. I still enjoy restoring bikes, they're just not very usable. Not that I expect to change anyone's views, but a truly roadworthy CT70 is something that can only be fully appreciated firsthand. Being able to go for an afternoon trip of 150+ miles, over 45-55mph roads without feeling beaten to death at the end of the day, on a bike this small, borders of the surreal. That I'm still saying that after close to 12K miles on the same bike (with the same engine) just shows to go ya', that, aside from my being seriously warped, there's just no way that could have been accomplished on a bone-stocker. No, it's not everyone's cup of espresso. However, it is one more interesting detail in the mosaic of the small bike scene. One that helps expand its viability. Longterm, restomods will help keep the whole scene moving forward and a lot of bikes on the road that would have otherwise been recycled and covered in decals that read "Fancy White Albacore".
