An almost new (20 miles max) KUOBA link for sale, taken off my wife's bike - http://www.koubalink.com/ttr250.html. Takes your bike down approx 2 inches and fits all models form 2003 onwards. The only mark on an otherwise mint item is that the lip seal on one side is slightly damaged from fitting and removal, this should not pose any problems as the link has a central grease nipple for maintenance purposes.
Would like to get £75 for it with postage. Let me know what you think.
Managed to get one but its 1mm smaller internal diameter. Not the end of the world but does anyone know of a suppler that does an OEM one? Size is 27x20x4
