theres a complete 750 on ebay at the moment for 1400 quid, which is pretty cheap cos its got all thee bodywork and hard to source bits with it, all you neeed theen is an 1100 engine.
theres also one for sale in the owners club thats eveen more complete with even the stock pipes on it, and he wants 800 quid for it, but its for sale only to club members. i guess it pays to be a member of an owners club if youre after something rare.
