Well for a start, anything with the 660 engine will be the same at the front at least, so...
- XTR
- XTX
- MT-03
I seem to remember the front is also the same as the Honda NX650 Dominator.
Don't know about the rear.
As an alternative, Wemoto say they will ship to the US/Canada, within 3-5 working days (plus whatever it takes to extract it from customs)...
