I think the 1200 Sportsters are set up like that. I'm pretty far out of the loop, as I quit riding many years ago. I drove a wrecker in the days when "chasing accidents" was how they decided it would be the best way to get the tow trucks to the scene. Seeing what happened to those that survived bike wrecks, slowly put me off riding.
Of course, one has to be a very good driver to get through that experience.
That hardtail you posted looks to have a very old bottom end with a Shovelhead top end. I don't know what would be involved in doing that but it's kinda cool that you can do it.
I don't think any of the guys I knew who had Harleys or other choppers or cruisers ever had bad crashes. The ones who got hurt or killed were on crotch rockets or riding drunk or stupidly on other bikes.
My older brother rode motorcycles for 40 years without an injury. He rode to work, rode in Europe, Japan, and New Zealand.
