I know your sort of making a moped modified to look a little more like a low slung motor bike. I just got shocks on the front from a fork that I swapped and made fit my motor bike. I just wondered if I found some parts I could use to make rear shocks, I'd try to mod the bike a little more. The swing arm to allow to shocks to operate and a idler pulley tensioner for my belt drive would mean a lot of changes. Maybe on a second build I might attempt something of the sort.
The way your working on it is real nice. Good to see modular crash bars that can be disassembled with the threaded bosses.
