This is Mike Ryan's current (August 2022) advertisement on Facebook Marketplace for the Yamaha Vision 550-powered Phasar that Malcolm Newell built in the early 1980s.
To save use of a magnifying glass, this is what the blurb says:
Seller's description:
£2,895
"With provenance, this super rare and the last ever 'Phasar Foot Forward Motorcycle' designed and built by the late, great designer (Quasar fame) Malcolm Newell is reluctantly for sale and the only reason it is available is that there is a Quasar here that I wish to see restored instead. This bike was built for Malcolm's daughter and was ridden by him.

Lying stripped and dormant for many years, this Twin Head Steer Phasar comes with another Yamaha XZ550 shaft drive bike so there are plenty of parts to complete this project. It also has an SU carb conversion. All of the GRP mouldings are typical Newell quality and are in excellent shape just wanting prep and paint. What a futuristic shape! The red bike is another one but it is representative of the look of this one when finished.

This bike will not need a fortune spent on it and will be a very valuable historical asset when finished.
Your opportunity to acquire and to own something very special to take to the bike meets and shows when done."

(NB The main photo on the Facebook ad is NOT the blue machine advertised – it's another Newell creation, a red Moto Guzzi-powered Phasar).
