Didn't anyone ever tell you not to give in to peer pressure?

Ever since the deal with Kelly to get the frame, lots of research has happened. If it were a legit Amen or original plunger, I would've kept it a plunger no matter what. The more I dug, the more I realized someone added a plunger kit in the 70s.

As the research goes, there is only one suspension worse then a hardtail and that's a plunger. Awful ride and awful handling. Plus they destroy your drivetrain because the  suspension acts independently since there's no swing arm. Talking to some old school chopper guys, the only way to fix them is to add a torsion bar. I decided to make it a hardtail instead.

True!

Even with a swing arm they're pretty dubious.

I see your point now.
I thought it would be similar to the older BMW models.  But, after looking closer, I now realize the BMWs do have a fully active swing arm.  Along w utilizing the drive shaft tube.  Just kinda hard to see exactly whats happening there as most are painted black and that suspension is hardly noticeable.
