There is no great mystery; it is just that the more obvious question was not explained in the Guy Martin programme.
From CM post the vehicle must have its own weight equivalent pushing skyward on the tyres. To enable grip for 1G needs about 1 1/2 G laterally at least. (Much as GP cars with 2G aero assisted downforce can corner way beyond the normal absolute limit of about 1G )
It is surprising how little the bikes lean upward, Note that all vehicles slope up at the front and are detectably steering up to counter the strong drift down.
Hopefully the lion never got bored or otherwise fed up. If it had a nervous wee on the boards, reducing the friction, the result could be intereting.
The probably Indian motor bike with leaf front spring and tank under the frame would ne 1930ish.
(I am still pondering what stock Seven roll induced oversteer would do here!)
