A friend of mine, now passed, bought the 'Cibie' Z-1300 engined Phaser back in the early '80's. He knew Royce(?)Creasy & Malcolm Newell quite well. Wrecked it out in Oz where he'd emigrated to. Did hear a while back it had come back to the UK for restoration.
Seemed outlandish at the time, but the modern maxi scooters are getting ever closer to the FF concept.
