I'm afraid I really can't become exercised about this interpretation of a Vincent - after all there have been plenty over the years, but none as far as I can recall by a sculptor. Funny, isn't it how we cannot find it in ourselves to view this motorcycle as a piece of moving sculpture? Maybe the hyperbole is a little overblown and maybe practicality has gone out of the window but for my money it's a beautiful object just standing there. The fact that it is capable of movement at all, albeit with the hindrances all so readily pointed out is a bonus! The fact too that it is an aural as well as a visual experience transforms it into a sort of 'installation'. I suppose Mr Decker could have merely taken a mould from a complete engine and fabricated everything else from bare metal...it would have looked the same...but this work actually lives! Now of course all of us Vincent owners do not become artists overnight simply because we own and ride such machinery, in the same way that if we spin a piece of paper in a centrifuge and dribble paint on it we are automatically Damien Hirst. The mistake and possibly the reason it did not make its high reserve price was to place this motorcycle in a car/motorcycle auction at all, rather than in a sale of contemporary art.
Of course it may not be art at all, and just the product of a sculptor who's also a known motorcycle enthusiast indulging an engineered hot-rodder's fantasy. It's good to debate.
