I've seen some builder's attempts at the BMW Custom Concept bike but nothing made/built has even come close to the origional renderings they teased us with. I currently have the screen saver picture of the one drawing, white tank, with the up-swept pipes and red engine block, single headlight. Humbly, I must admit, that this picture gives me a chubby. I was contemplating taking on this bike rendering as my next project after my HP2e is finished. Anyone got an opinion on the red engine block and up-swept pipes? Just curious that's all. Cheers inmates!
