ASB has partnered with twinmotorcycles as far as parts are concerned. ASB business isn't set up for tooling, etc...twinmotorcycles is just outside of Amsterdam, Netherlands possibly better equipped, but couldn't say... only speculating as to what they are capable of doing. ask easyridernl...he works at twinmotorcycles.
Al at ASB has two 1125's, at least I think he did if he hasn't sold the one he listed. Maybe ask him where the support will be.
None of us really know, unless someone on the forum is connected that can give a hint or two as to what the future holds in parts support for the XB and 1125 line.
