Bikes have become legal again in Jordan. Harley Davidson has a big new shop on the Dead Sea road as you leave Amman (near to Climbat, a big new climbing wall).
Not seen any other Motorcycle dealers though, although I have seen a Honda GL 1800 with the rider wearing "Honda Jordan", on the back of his jacket.
Harley had a big rally here in Aqaba last October, riders from all over the world I believe.
Seen a few sports bikes as well, but all in all Bikes are still very rare in country.
Also check out "Big Boys Toys", they have quads etc and so should be able to help out with repairs etc.
