It makes me laugh when you realise everything engine-wise has been tried at least once before. Some of the pre-WW2 supercharged race stuff looks like it's from another planet, add in the early 60s Japanese stuff that revved to 18,000 rpms.
 
Yamaha had a hydraulic driven frontwheel. Quite simple with a hydraulic pump at the frontsprocket
