the Hyosong gt 650 is basically a Suzi sv? 650 engine.
and from mem. the bike books a while ago had some of the engine cases and the webbing to support the bearings etc was of top quality.
and i think Hyosong started out in the early-mid 80’s casting / tooling gear up for Suzi and then bought their out dated patterns , patents etc and branched out into their own bikes while still working for Suzuki.
i’ll now have to go look at the specs on this quad thingy.
