I have the twist throttle on my LTR.. I bought it direct from Motion Pro here in the states.
You may want to try to contact them as they may be willing to ship it internationally to you, if not, I am sure they could point you in the right direction...
Motion Pro is your best bet. I would just do a search on google.com though. I had a quater turn on my YFZ and hated it though. I needed something that had more throttle control.
