Had a kumicho R back in the day from ironhorse. It was fun and worked well... I don't remember the swing arm being two pieces though so maybe you guys are talking about something else?FWIW, I've seen all DHR sizes available at Go-Ride in the past. The main "downside" seemed to be colorway and perhaps shock model. But regardless, you exactly right: Kumicho > Tr450
IH needed more of those people!
