unfortunately Peter is right, and due to whatever certification/registration/approval matrix required we will never keep up with the latest to come from Zongshen.
Wanted so much to be leaving in 8 weeks on a new RX4 but that isn't happening,
Having buried a RX3 into the earth as hard as one could and handing her off (sold at loss) to someone hopeful of a rebirth I
moved on to bigger and better things
Like a 20 + yr design air and oil cooled single with 5 measley gears that is know for RTW travel with nominal issues, a DR650
Total cost is a bit more than the RX4, with the mods, but not by a LOT, as I got the DR used with less than 1K miles for <$4K
So...while I embrace what CSC is doing(and won't forget the break-downs that Gerry and Steve helped me out of) , IMO it's not the best timing for what I need.
Merry ( my beloved RX3) will be sorely missed...she was a great bike and a LOT of fun.
I hope Sunny (the DR's name) will be up to the challenge the RX3 left
