I have to agree with Tony its just a badge thing and as the ER6 f is not available here in Thailand... the Ninja 650r is the same bike as the ER 6f, sold in Thailand using the Ninja badge.
In the U.K Kawasaki sell the ER 6f with A.B.S at 5,425 pounds sterling(282,000 baht) which is the same bike as the Ninja 650r :? for sale here at 257,000 baht. The ER 6n retails for 4,699 pounds sterling in the U.K without A.B.S (244,000 baht) or here in Thailand with A.B.S. for 245,000 baht. One interesting point is that Kawasaki U.K offer the Versys, a bike not available in Thailand :? with optional A.B.S at 300 pounds sterling (15,600 baht).
