I wonder if he was tempted to sneak in "Feels a bit gutless compared with a Vincent"?
In 1950, there wouldn't be too many bikes where this didn't apply !
An Ariel 1000cc Squaffer, maybe, can't say I've ridden one nor seen reports of huge torque ?
Phils autobiography, great read, could probably say as to his whereabouts.
Not immediately to hand here though.
He sure worked on a lot of projects/developments.
And cast a wise eye over many.
That undamped rear suspension sounds a little problematic.
Was that ever improved ?
