+1. Agree with rtking. Don't pull the plug. The RX3 is worth the wait.
I'm in the same boat on the TT250. I called last week to add the skid plate to my order and Ryan gave me an update on the progress of the shipment. Could just be a hold up in port or customs to get the bikes officially off the boat. Then there's the unpack, assemble, test, and re-crate for shipment to your door.
BTW.. CSaddict, i see you've got an EN450 bobber project in your sig. I have a EN450 (454LTD) brat/bobber style bike as well that I put together last year. Here's a link with some pics.
