Things that make me go ohh #9 Prototype motorcycles.
For every bike that makes it to the production line there's plenty that never see the light of day. Some of those quirky motorcycles that do make it aren't always the success they could've been (Honda NR500....)
Which makes this pic even more interesting. It's a Yamaha seven valve head that's bolted to two banks of four cylinders. A V8 with more valves than my maths can calculate. What happened to it, why have I only just found about this mystery machine?
I can remember some company making V8s by grafting two FZR motors together back in the 90s, the concept obviously never took off, shame.
