My thoughts are, why would you!
I think people are sold on nostalgia; however they will probably tell me its less technologically advanced and therefore less likely to go wrong or I can fix it with a spanner or unaided by any diagnostic equipment. Having said all that I admit I have never ridden one, nor would I want to. I thought the days of good old British inefficient engineered motorcycles had long gone, however sad it may be. Why try and bring it back, isn't that what killed off the industry in the first place, no imagination and little investment in the future of our engineers and designers. So what do we do, go and by the bike for nostalgia.
'gets off horse'
just my thoughts
oh and edit: cheap, its a cheap motorcycle
