yep, thats a rare one, an RE5 wankel rotary powered "superbike" from the 70s, massively overcomplicated, hugely unreliable, slow as feck, unbelievvably heavy maintenance nightmares and no spares left anywhere (cos they sold bugger all of 'em in the first place)
they had 3 seperate oiling systems, liquid cooling that (from memory) involved the water pump crapping itself into the rest of the motor, 'orrible 70s suzuki electrics and so the list goes on........until it reaches the styling which included the instruments being placed into a 'barrel-like' binnacle with a tinted cover that spun back round the outside to reveal the instrument faces behind it. the tail-light was in a similar shaped thing so it was at least as ugly at the back as at the front.....
i'm sure that they have their devotees........i just hope never to meet one
